Yesterday We went to the local range and I took 4 fireams that I regurlaly like to check ocasionally for reliability. 2 were my glocks, they ran fine in 45, and 9. One is 15 years old and still runs like the day I bought it if nt better, G30. then my LCP which feeds anthing also, my wife got the chance to fire it for the first time and she loved it.
Now the problem, my keltec, pf-9, which has been reliable and always ran great. I had taken a box of old 147 grain hollow poits with me, the gun had previouslly ran with 115 grain FMJ's and HP's with no problems of any kind.
Not so with the 147's. every other round would not chamber. The gun went into battery, ejected the empty cartrage. But would not chamber the next round, I had to manually re-cock it each time.
Is this a magazine spring problem, or a recoil spring isssue. Finally it fired off the last few on it's own. But as soon as I went back to the 115's it fired a box with no problem. Thoughts?

None of the above.
It is a 147 grain ammo problem.

Early PF-9's were chambered with a very short rifling leade, and 147's will not always chamber in them. Later, the leade was changed in newer guns, but still.

It has been a long standing recomendation over on the KTOG.ORG site to avoid 147 grain ammo altogether in both the P-11 & PF-9.

I'm confused, did it not jam them far enough into the chamber, or did it not strip them from the magazine?

It didn't strip them from the mag. Thanks for that info, I remember now hearing that a while back, but have read so many good and bad 147 articles, I completely forgot untill you answered my dilema. Know I need not start messing with that little pistol. It realy is a gem for what it is. Thanks guys

huh. Mine eats 147's just fine, along with anything else. I handload them, both Gold Dots and XTP's.

The same barrel is in a P11.
I throated a barrel for 158 gr LSWC or XTP bullets at 1.169".
They feed just fine with the stock recoil spring.
