Glock 19 vs. Sig Sauer P365 XMacro Comp: Best Compact CCW?

We pit the Glock 19 against the Sig Sauer P365 XMacro Comp in a battle for the best compact concealed carry gun.

    The Glock 19 has been a staple of concealed carry for a long time, achieving high marks for its compact size, good capacity, and outstanding reliability.

    But when Sig recently released the P365 XMacro Comp, we got the idea they were gunning for the championship.

    Bearing that in mind, I pitted these two heavyweights against one another to see who would come out on top.

    So follow along as we look at specs, features, ergonomics, range performance, and a whole lot more to determine who is the ultimate concealed carry champion…

    Both camps have enormous followings; who will you cheer for?

    Glock 19 vs. Sig Sauer P365 XMacro Comp: Fair Comparison?

    You might say this isn’t a fair comparison out of the box…and you’d be right.

    So, I altered a few things to make it the closest match-up possible.

    Since the XMacro Comp already has an integral compensator, I added a Radian Afterburner Compensator and Ramjet Barrel to my Gen 5 Glock G19 MOS.

    As both pistols support a red dot, I ran the Romeo Zero Elite on the Sig and a Crimson Trace RAD on the Glock.

    For this comparison, I chose a few categories I could compare the two firearms and test them to determine which one offered more.

    At times, there was a clear victor, but other times…it was tougher to call. At least one bout was a straight-up draw.

    To address my partiality…I have carried and shot models from both companies for years and have enjoyed products from each of these firearms giants.

    That said, I left feelings aside and ran both of these models side-by-side in an effort to see how each performed in the chosen categories. The results are simply my opinion.

    Now, let’s dig into the specs…

    Now into battle, we ride…keep reading as we run through each category to determine a victor…


    The G19’s reliability has been proven for many years — a Glock version has been around since 1988.

    Many law enforcement agencies and military units have fielded the weapon around the globe.

    The XMacro hails from the P365 series, and while that might lend some strength to its reliability overall, this gun is somewhat of a departure because of its integral compensator.

    That said, I have experienced nearly flawless performance from both guns during testing.

    With the scales nearly even in that regard, the Glock takes this round because of its long track record.

    Winner: Glock


    Glock has not been the most ergonomic gun, but they have tried to improve the platform over the generations.

    For my big hands, shooting a Glock without an extended backstrap is a recipe for slide bite.

    The grip is square-ish and a bit thick, measuring 1.26 inches wide and over 2 inches from the backstrap to the front. For me, the length of the grip is just enough to accommodate all my fingers though my pinky crowds the magazine a bit.

    Glock, thicker than a Snicker

    The XMacro has a square-ish grip, too though a more svelte overall size, with a thinner grip (1.1 inches) and accommodating beavertail. Its grip is also slightly longer, giving my pinky room without crowding.

    The distance from the backstrap to the trigger is pretty close in both guns, though there is more bulk on the Glock and the Sig makes up some distance with the forward-angled trigger bow.

    Both guns are well textured, and I appreciated the inclusion of forward and rear serrations for manipulation.

    Winner: Sig Sauer


    To determine accuracy, I carefully shot 2- and 3-shot groups from 7 yards using the same ammo in each gun.

    I also used red dots on both. The use of red dots may have favored the Sig because the Glock had an advantage in sight radius or the distance between the front and rear sight.

    XMacro left – Glock right

    Regardless, I believe the longer barrel in the Glock resulted in slightly better accuracy.

    The XMacro groups were bigger than 1 inch on average, and the Glock’s groups were 1 inch or less.

    Winner: Glock


    An entire segment of the gun industry is dedicated to customizing Glocks. Notably, black was the only choice for a long time, though things changed with the release of the 19X, which came in an FDE color.

    That said, there isn’t a great deal of customization available from the factory other than choosing your sights.

    Most Glock customization consists of adding aftermarket parts, accessories, and upgrades.

    On the other hand, Sig doubled down with modularity in the P365 series. Besides the options available at Sig Custom Works, shoppers can build a completely custom P365 with a builder on Sig’s website.

    There are a plethora of options for frames, slides, triggers, colors, and coatings, not to mention the Fire Control Units (FCU) they sell, allowing you to “roll your own.”

    I confirmed with Sig the XMacro components will ultimately populate this builder as well.

    While there is no doubt an enormous aftermarket for customizing Glocks, this round goes to Sig, who offers much more variety to the customer upfront.

    Winner: Sig Sauer


    This category isn’t too much of a contest. The Glock 19 has a capacity of 15+1, but the Sig comes in strong with a capacity of 17+1.

    Winner: Sig Sauer


    Red Dot Capability

    There are several benefits to having a red dot, so I’m pleased that both the Glock and the Sig are optics capable. However, that makes this round even.

    Winner: Draw


    Glock triggers are often fussed about, but I think they are fine for a striker-fired gun. I think the Gen 5 Glock trigger is definitely the best they’ve made.

    However, Sig’s trigger has a couple of advantages in my mind. First, it doesn’t have a trigger safety, so the surface is smooth and consistent.

    This may seem like a strange preference, but if we hold to the fact that our trigger finger discipline (and adherence to other rules) are best practices, I believe this makes a trigger safety redundant.

    I prefer the flat trigger bow of the XMacro, as well as the forward angle.

    Incidentally, the press, travel, wall, break, and reset of both triggers felt fairly similar overall though the Glock has a much louder break.

    Winner: Sig Sauer


    I had no idea what to expect when it came down to testing the felt recoil mitigation both compensators offer. When I tested each gun separately before, I recalled a significant difference allowing faster follow-up shots.

    I was uncertain if the greater mass of the Glock with the Afterburner or the smaller Sig with integral comp would rule the day.

    The only way to compare was to load up magazines and fire both in controlled pairs.

    While both compensators absolutely worked well on both guns, the Glock with the Radian Afterburner was a little bit quicker to target on recovery from recoil.

    Glock 19, left, and Sig, right.

    We recorded some slow-motion footage of this, but it might be hard to tell the difference without personally feeling and seeing each sight picture.

    Winner: Glock

    Bang for Your Buck

    Pricing for the Gen 5 G19 MOS is around $620. In order to make it competitive with the Sig, we added a the Radian package, which costs between $370 and $390. That means, in total, Glock sits at $990+.

    On the other hand, Sig Sauer’s P365 XMacro Comp comes in at $799.

    Concealed Carry

    From the outset, the G19 is just bigger than the XMacro. Perhaps most important — it’s thicker.

    The grip is slightly shorter on the Glock, and that’s an advantage, but the difference in width between the two guns (XMacro is .16 inches thinner) makes the Sig hug closer to the body for concealment.

    Using a PHLster Floodlight IWB holster, I wore both guns and turned different angles while carrying in the appendix position.

    On me, the Sig had less printing than the Glock when I moved around.

    It’s noteworthy that the Floodlight was a little big for the XMacro, so the overall footprint could be trimmed down even more with a model-specific holster.

    Winner: Sig Sauer

    Final Verdict

    I had a pretty good idea which way some of the rounds would go, but a few actually surprised me.

    Out of 10 categories, the G19 won two, while the XMacro won seven, and one was a draw. For this contest, the Sig Sauer XMacro came out on top.

    Keep in mind I am in no way saying the Glock 19 isn’t a good choice for concealed carry; it is!

    I simply believe the XMacro offers more in a few different categories.

      I have a heard time trusting a company that decided they didn’t need trigger drop safeties because they made their triggers light enough. Then, when they obviously did thier math wrong and the p320 started going off on its own, had to recall them and put in a lighter trigger and change the disconnect. Sig doesn’t seem to have a problem dangerously beta testing on its patrons They eventually end up with a solid gun, but you never know if you could be a victim of their thirst for innovation. Glock on the other hand hasn’t changed anything to both their advantage and detriment.

      Totally agree with the outcome but that can be due to biases on my part and other shooters mileages may vary i.e. according to day, product preference due to any number of reasons i.e. weight, colour, design, overall quality, manufactures reputation, and on and on. I really appreciate unbiased comparisons so that you much.

      Sean, first off I do really enjoy your articles. I have to say I feel this is not a good comparison article. Glock does not innovate they just keep making the same bland gun in different sizes. Its the aftermarket companies that do the innovation to make glocks better. I buy Sig because they are constantly coming out with new great guns and improving the current line up.

      This comparison should have been a g19 to a P320 xcompact. Put dots on them then compare. To take a g19 and do all the upgrades and then compare it to a stock gun just doesn't make sense.

      Let's see an article on PSA rifle and add actual quality components and then compare it to a DD stock rifle. It's just not apples to apples.

      Once again you write great articles and I appreciate your input.

        We weren't sure how this comparison was going to shake out when we started, but tried to make it fair. Your points about innovation and aftermarket support are certainly not lost on me. The Macro is something different enough that's it is honestly tough to compare with a lot of current options.

      Sean, you have the most magnificent whiskers ever! I'll take the Xmacro when they mate it with an XL slide. No compensator on a carry gun for me. I don't want gas and debris blowing up into my face when shooting from retention. I'm really annoyed with Sig because they made such a big deal about their modular FCU, but now they won't sell the parts to build a gun around the FCU. Tell me again why the modular FCU was such a Great Leap Forward? The only way to get a Sig P365 X-macro with an XL slide is to buy two different pistols and swap the slides. The marketing department at Sig has triumphed over the engineering department. In the meantime, I'm running a Springfield Hellcat Pro that came with five mags from the factory, is exactly the same size as the Xmacro, and cost ~$300 less. Sig is not showing me the value proposition and I'm not showing Sig any love at the gun store. Bravely onward!

        I'm not sure that the FCU is a great leap forward, but it certainly presents some options to the consumer not previously offered (incidentally an undercurrent of this review). I'm delighted Springfield is keeping you covered and I understand your position. Glad you've got what works for you.

        Bull, they already DO mate with the XL slide. Sig is selling all the different grip modules as aftermarket options right now. They also include 3rd party grip modules by Wilson Combat, and other makers, that are very tempting.
        You can buy the X-Macro grip module you want for $79 and use it with the P365, P365 X, or P365-XL slides. Takes all of 2 mins to swap the FCU from one grip module to the other.
        How is that a bad thing?
        FWIW, these parts sell out very quickly; if you see something you want ... might need to move fast to secure the item.

      I enjoyed this video and its presenter. And depending on your experience as a gun owner and concealed carry practitioner, these reviews can be quite useful. However, I always chuckle at the overall notion with many of these comparisons because so much of the evaluation criteria are purely subjective. The same goes with most "Best ______" articles. They're helpful but only up to certain point.

      Personally, reliability is my prime concern and I find the disparaging comments about Glocks curious. As a former federal agency Firearms Instructor, having watched thousands of shooters on the line using Glocks (of various denominations) for decades, the pistols have performed as outstanding pieces of engineering. The SiGs may also live up to that standard and time will tell.

      There was an old adage floating around years ago saying the best gun was the one you liked the most. I still think there is a lot of truth in that idea...

        Brian, thanks for your service and kind words. As an instructor you know what it is like to get a group of students with varying levels of experience. We have that on an enormous scale and do our best to present the information accordingly.

        I feel the same about Glock, carried one on duty for many years and can report similar performance. But, as you said, most of this is subjective.

      Hi Sean,
      I purchased a P365XMacro and am disappointed because it shoots down and to the left right out of the case. I’ve had others shoot it with the same results.
      I asked a local gun store about this and was told to start beating on the sites. I went to other shops with basically the same instructions.

        Howard, I say this as a former law enforcement handgun instructor, most of the time low left shots are caused by anticipation of recoil. Do your level best to isolate your trigger finger from the grip you've established. Let each shot be a complete surprise. Since there is a wall on the trigger, press it back to the wall and hold it, then break the shot when you're on.

        Try using just the tip of your finger in the trigger too.

        If all that fails, try using a rest of some sort to stabilize yourself and/or the gun. Do everything you can to eliminate yourself as a contributor to inaccuracy. If you're still coming up with the same issue, you might want to reach out to Sig.

      Nice bogus test! Why didn't you just test them straight up, like most of us use them? I admit to being a Glock fan-boy. I carry a G30. Where I live, (Commiefornia) capacity is not an issue. Anyway 10+1 works pretty good. Plus I carry 2 G21 13 round mags (Legally grandfathered for extra need.) What would tip the scales for me, in your test, to the Glock is one category ACCURACY! The only stat that really matters in a firefight!

      There is simply no comparison here. The Glock is a Volkswagen, the Sig Sauer is a Porsche. Or Ferrari. Sig may cost more, and it is worth every penny. Ask the Army, Navy, Marines and Air Force why they all picked Sig for their weapons. Pistols, rifles and machine guns. Sig is the best.

        Steve, I take your point but I think there's still room for comparison when the Glock is still chosen by many special operations units and countless police agencies. Preference is one thing, but Glock has some impressive numbers in those area. Whether they continue to hold that grip may be another tale.

Then I would also have to wonder why when the SEAL's send 33 of the "Most Elite Snipers In The World" to USMC Scout/Sniper school only 3 made it through the course. Oh well another burst bubble.

        String, this is a good point. In most scenarios I'm not firing anywhere near my face but I'd be curious to test your concern on the range (in a safe fashion of course). I think the benefits of the comp outweigh the risks currently, but I could change my mind after testing.

      For my needs the Sig P365 XMacro Comp. Hands down,beats the Glock. Value, capacity and how it fits my hand. My little finger barely makes it on the Glock. I too have slightly bigger hands. Having to add the compensator is a modification that does not have to be done from the stock Sig.
