I went through several brands of plastic framed pistols, each one seeming to do better for me than the previous ones till the ones just previous to the CZ P0 guns.
I bought a P07 in .40 S&W after having repeating failure to fire issues with the previous brand of plastic framed guns (not naming brands in this thread so as not to start discussions other than on CZ P07/P09 guns).
That P07 sold me on the idea of buying another one. The second one was a P09 in 9MM. I'll attach a picture of my P07 grouping ability. Oh hell, might as well put the P09 9MM group up, too. Or partial group. With the P09 it took me 3 shots to realize they were tearing the same hole in the paper. So I just took a picture of those three rounds as the group just got bigger.
Seems both these guns "like" light bullets. Oh, the P07 is one of the older "DUTY" model guns.
With the .40 S&W P07 group, the flyers were my fault. I knew it when the gun went off, that I was wandering off POA.
P07 group. Thirteen shots (Nosler 135 grain hollopoints in front of a near max charge of Blue Dot) at 12 yds.
P09 group. First three shots from the P09 9MM (Precision Delta 115 grain hollowpoints in front of a near max load of Blue Dot).
