I've owned/own a few.
Had a beretta storm a little over 10yrs ago, in 45acp. Worked great, accuracy fell off around 75yds.
Built what was the first cz 26 semiauto subgun conversion as a carbine, it's 7.62x25 tokarev. Never really played with it past 50yds. Ended up selling it.
Built an uzi semiauto carbine from an smg parts set, still have it. It's sighted at 50yds, but life got busy right after I finished it, so all I know is out to 50. Seriously considering sbr'ing it, so it can look like an uzi should.
I have a brugger & thomet tp9 sbr, with suppressor. It's sighted around 25yds. Got it while building the uzi, so haven't gotten to do a lot with it either. Shot a 3-gun match or two with it, 20yds and less.
While I have had a like for the uzi since I was a kid, the tp9 is so short, and light, there is no comparison. The uzi is quite heavier than it appears.
Always wanted a Thompson, since I was a kid. Shot a couple. Maybe one day......
