I've subscribed to Gun Test for several years. Highly recommend!!
Gun Tests staffers are currently testing a Ruger-57 chambered in the 5.7x28mm round for the October 2020 issue of the magazine. The 57 is pitted against two other 22-caliber handguns, a Rock Island 1911 chambered in 22 TCM and a KelTec PMR30 in 22 WMR.
Our First Look at the Ruger-57 showed it had good accuracy and speed overall. Also, our test team’s notebooks listed a few specifics about this newish semi-auto handgun:
