Editor’s Note: The Ruger MKIV 22/45 is the latest iteration of an excellent target and plinking pistol design that has been around for decades. Exceptional ergonomics and great reliability are complimented by modern features such as a rail for mounting optics, a threaded barrel, and a simplified takedown method. These guns feature a standard 10+1 capacity of .22 LR, and all have cold hammer-forged barrels to ensure that the gun will last for years to come.
