SO EARLIER THIS WEEK, I EXPERIMENTED WITH SHOOTING THE 5.7 X 28 CARTRIDGE: My first impression was how small and light a box of 50 cartridges was. I first shot through a Ruger 57, which was very unsatisfactory as the trigger safety was hinky. Sometimes it worked, sometimes it didn’t.

I switched to an FN57 and it was better, though it stovepiped on the first shot. After that things were smooth, and the gun was certainly low-recoil and accurate. I doubt it’s the cartridge’s fault, and those were rental guns at the range, which have probably seen a lot of use. Still, not the most auspicious introduction to this new caliber.
