All I can say is that this little pistol continues to amaze me. I got my CZCustom PT-9 OR plate on Saturday, installed my new Holosun 507k-x2 red dot, practiced a little dry fire on Sunday and Monday, was at the gate this morning when the gates were opened.
Very windy, but from 4-5 o'clock direction, clouds brewing, rain on the way. Set up at 25 yards, looked where the dot was relative to the iron sight zero, moved the dot a few clicks and was done in 10 rounds, all with IMI 115 JHP ammo. Grouping was a little bigger than I expected, but I went to the 100 yard range anyway. The first ten IMI rounds sprayed on target 1, so I loaded 5 rounds of Atlanta Arms 115 JHP and shot a good group on target 1, so I put up target 2, and proceeded to shoot two good groups with the AA 115 JHP, as recorded in the video below.
https://youtu.be/JY6otR_nV6AI fired a few more AA 115 JHP rounds after these, but couldn't match this 10 shot result on this very windy day. My friend had his CZ Custom bull barrel 75 in 9mm there, so I shot a few rounds with it, but the open sights were not good for me due to my eyesight limitations. The gun itself is very, very sweet. If he puts a red dot on it, I'm sure I will be able to shoot it fine.
The little Holosun 507k-x2 sight allows cowitness of the stock sights, fits the slide width perfectly, and it fits and looks good on the subcompact pistol.
A great day with the little P-10S OR subcompact.
