[Review] Rock Island 1911: GI Midsize

Quick!  Rock Island Armory…what’s the first thing that comes to mind?

For me, it was…cheap 1911s.

And it’s TRUE.

But in the best possible way.

Follow me as I put their sub-$500 GI Midsize 1911 through the ringer.

Rock Island Armory (RIA) manufacturers their 1911s in the Philippines and passes on the savings to us.

When I ask people about RIA…words like “affordable” and “best-bang-for-the-buck” always come up.

I’ve handled them in stores since it seemed all the local gun shops around me had them.  But my first chance shooting them was at SHOT Show 2017.

And boy was it fun…especially with their 6″ competition 1911.  Plus…they had one of the nicest crews out there.

But since I’m mostly in California…I had less choice to choose a test gun.  So I went with something out of the ordinary…a plain Jane GI (government issue) that faithfully reproduces what was issued as the WWII sidearm.

Except I chose the midsize which swaps out the full size 5″ barrel for a 4.25″.

Who Is It For?

If you’re looking at a pretty faithful reproduction of the first generation of 1911s…you can’t go wrong with Rock Island.  The midsize is the original “commander” size.

Or if you just really want a 1911 but don’t have a lot of cash…the GI is a great place to start.

Fit & Feel

Of course, when most 1911s are much more expensive (check out our Best 1911s article), you’re going to have to cut some things.

The parkerizing (black coating) was great and I couldn’t find anything that was too thick or too thin.

But you can see the machining marks at some angles…like at the curve of the slide top.

And personal gripe…it doesn’t have a bushing to contain the barrel and recoil rod so instead they have a thicker barrel that requires a paperclip to remove.  Lots of YouTube videos on it though…

And since it’s a GI model…they have GI sights.  Low profile and easy to draw out…but not the best.  Still…lots of options to switch them out afterward.

How about the trigger?

On this RIA…it was awesome.  It averaged 4 lb 11 oz and with a glass rod clean break.  Note…the other RIA’s I’ve tried at gun stores were not this good.

Not saying that they polished up my trigger or anything…but it was better than my $1000 Springfield after I did a quick 1911 trigger job so it could be luck of the draw.

How Does It Shoot?

The .45 ACP round has some kick (Best .45 Ammo for Plinking and Self Defense).  And when you have a shorter barreled handgun…you’re going to feel it more.

So I expected it.

It wasn’t excessive…but it wasn’t fun either.  I don’t think I could shoot more than 100 rounds in one range session.

Now how about the accuracy?  I shot some Armscor .45 ACP along with some American Eagle at 10 yards off a benchrest.

Here were the results of the Armscor:

And the American Eagle:

Pretty respectable and definitely minute of badguy.

I had 3 other friends shoot it and they all had it go towards 7 o’clock…so it wasn’t me flinching.  If you need to brush up on some handgun…check out our Ultimate Guide to Shooting Accurately.


I’d estimate recoil was 30-40% more than a full size 1911 shooting the same rounds.  You’re going to feel it.

And for two of us (hi Ryan)…we experienced some “biting” from the GI hammer and beavertail due to our very high grips.  It’s just what happens from the design.

And afterward…I realized the hammer was indeed hitting the top of the beavertail.  It made a decent dent in the metal itself.

Reliability was great after a 50 round break-in.

For the first few mags, I had some double-feeds.  But once I loaded up the mags (a mixture of factory and Mec Gar 8 and 10 rounders), and left them overnight…the 2nd range trip was flawless.


The box is pretty bare bones…and I might have gotten an extra mag for testing.

Rock Island 1911 with Magazines
Rock Island 1911 with Magazines

Action Type: Single Action

Barrel Length: 4.25″

Capacity: 8+1-Round

Cartridge: 45 Auto (ACP)

Finish: Parkerized

Front Sight: Fixed

Length: 8″

Weight: 2.38 lbs

By the Numbers

Reliability: 4.5/5

Some reliability issues in the beginning but fine after 50 rounds and magazine break-in.

Accuracy: 3/5

It’s not the barrel or the handgun…it’s the standard GI sights.

Ergonomics: 4/5

I love the feel of 1911s and this captures that.  The shorter barrel is also easier to move between targets.  But the hammer bite kind of sucks.

Looks: 4/5

Great parkerizing and you have to really nitpick to see the machining marks.  But remember…it’s under $500 for a reliable 1911!

Customization: 5/5

It’s a 1911 so the sky is the limit.  Check out our Gunsmithing section for ideas.

Bang for the Buck: 5/5

Again…it’s a reliable 1911 for under $500!

Overall Rating: 4/5


So…am I purchasing the RIA 1911 GI Midsize ($495)?

No…but if I could get one of their full-size Tactical models…I totally would.

For about $100 more you’ll get a rail, better sights (fiber optic), and a more robust beavertail (bye bye hammer bite).

With the test of the GI Midsize…I’m sold on the quality and reliability of RIA.  And also learned that midsize is not for me.

Do you have a RIA…or are you planning on getting one now?  Let me know in the comments!  Check out more of our favorite 1911s in Best 1911 At Any Budget.

I have the GI series Compact. For me,it is just right, even though I have large hands (xxl gloves). Sights are right on for me, although I will go with some easier to use sights in the future. 150-200 rounds in a range session is not unusual, and just starting to feel like I need to stop. Haven’t experienced ant slide bite, myself. Overall, definitely sold on this pistol, and is my full time concealed carry.

I’ve always been a revolver guy, decided a few years ago to get a semi auto. Bought an eaa witness. Loved that gun after I put adjustable rear sight on it. Bought a RIA gi 1911 couple weeks ago on sale from dunham’s. Just because I wanted a ww2 look alike. Sold the eaa and a beretta 92fs to buy a RIA tcm combo and a midsize within a week. Straight out of the box I got dead nuts accuracy. 3 inch groups at 30 yards. Never had a .45 before. Deffinately a rock island 1911 guy now.

Hi Eric. Altho I have a Beretta 9mm, two of my friends have the 1911s, & would like me to 'man up' to the .45 cal., from the 9mm. My two initial concerns are the recoil & the issue with the sights. My Beretta fits my hand so fine, & the recoil is minuscule compared to the 1911s I’ve fired. AND, w/a laser dot, sighting/aiming is no issue. Both friends tout the stopping power of the 1911`s, & state that the cost of ownership is not that much more than a 9mm. Right now, the Rock Island Armory 1911 GI… Read more »

I have had three 1911 .45s over the years, two were Colts. My full sized RIA GI is my favorite, I have had it about 4+ years now with no problems. It came from the factory shooting dead-on windage so I have never touched the sights. I have heard much about hammer bite over the years but with at least 40 years of firing 1911s I have never had this happen to me, and I have big hands! I love my RIA GI 1911, I have put several thousand rounds of most of well known brands, ball & some hollow… Read more »

Ive had a full size GI model for a bit over a year now. Excellent gun. Put in a Wilson Combat spring kit, extractor, firing pin, and magazine; not for any particular reason, just because I wanted to upgrade it a bit.
