I have to say that I'm extremely impressed with it, free hand I could keep a 2" group at 25' (which for me is pretty good I guess). The dealer recommended I use CCI mini mags so I bought 400 rounds of those & I decided to try the Winchester SuperX (figured it had a higher velocity thought it would be ok) so I also bought 300 rounds of these. Well the CCI's worked flawlessly, chambered/fired 300 rounds no problems. The Winchesters on the other hand was a different story. I guess being on the range it wasn't such a big deal but out of 200 rounds I had 8 times in which the gun did not eject the spent casing after the 1st time I could actually hear the difference and new that I needed to manually eject. I'm pretty sure this was ammo failure & not gun failure because it never happened with the mini mags. I will say it was nice not having to spend a fortune on ammo for a nice day at the range. Hope this answers some questions and anyone thiniking of getting one, I would recommend it.
