Man that thing packs quite a wallup. It's pretty snappy. Moreso than the .40 S&W I've shot before. A little less that the .357 mag revolver i've shot. Overall, about as muck "kick" as a .45, but a whole lot snappier. It actually seemed a bit quieter than my 3.9 in barreled sig 228, but that may be because after the 1st shot all i could hear was ringing... (no ear protection, as it was just 2 mags worth, moreso for a function test) One funny thing is that the freakin brass flies at least as far as my AK does. Minimum 30 ft away and 20 feet in the air. For a pistol, that is quite impressive. Go external extractor, course the 1600+ fps muzzle velocity probably helps. I asked this in the other thread, but i was curious if anyone knew about what the 7.62 x 25mm is equivalent to. Maybe .357 sig at least?
