That is sweet - those are nice - I really like the Coyote tan colored one - nice to see the EOtech match it too
I am new to rifles - I'm not really sure what to expect out of a "good" group. I haven't shot my PS90 past 50 yards, but I got a 1/2" group at 50 yards w/ the EOtech. I guess that's not too bad, especially since the trigger is kinda heavy. I read about some of these 9mm carbines getting 4" groups at 100 yards.... Like I said, though, I haven't gone past 50 yards. The group doesn't touch, but a 3 round group was about a 1/2". I don't know if that qualifies as a tack driver, but I guess its ok. The PS90 is not known to be a tack driver anyway. I have seen some complain about large groups with the PS90, but I think they may have rested the barrel on something, and also were using the crappy stock sight.
