I took the PF9 to the range today. All bad. I fired 20+ rnds of Fiocchi 124 gr and still having the same problem. Switched to RWS 124 gr hardball and it is jamming on the top of the chamber. Same problem I had with the 115 gr.
I called KelTec and they are sending me new recoil springs. If that does not fix it, then it gets shipped back to the factory.
I took my very neglected Marlin 700 with me and it salvaged the morning. I slapped a 3x9x32 scope on it the other day and sighted it in at 50 yards with 36 gr mini mags. 1st 3 on paper low and right. Adjusted the scope and next 12 were in the 10 ring. I used the top of the lower cross hair post, duplex reticle, at 100 yds and got 7 out of 10 into the 10 ring. Darn good little $80 gun.
It shoots better than my Ruger 10/22.
