Is it my little finger or the Mag?

[greenego]

I went to Norris and shot the Kahr PM9 I recently purchased. The outcome was, the gun was flawless with the six round mag, but had problems with the seven. With the seven round mag the gun did not chamber properly. The slide also didn't not lock open after the last round. If the mag is not the problem, it must be they way I am gripping the gun with the extended mag. I must be putting a little downward pressure on it with my little finger, causing the mag. not to be seated. Anyone else have this problem?

Yea I had the same problem when I put an extender on my PM40 mags. When I took it off the problem went away.

The first round chambering prob is common: you using slide lock release to chamber first round?

Do it. In the manual, and often necessary for a good while, especially with the 7 rounder since more pressure on the spring.

Far as not locking open, compare the tops of the followers in each mag...look the same? The 7 rounder SHOULD lock open. Does it lock open when you hand cycle the slide?

Another possibility is the mag lock...they made them from polymer for a while and then metal. Could be that it's not holding the longer mag firmly enough for the lockback to occur, but that's doubtful...most common symptom of that is that mag drops during firing.

You shouldn't have to worry about pinkie pressure..mine works okay...

I have two of the 7 rounders, we can test in your gun on Oct 11th if you're going, or if you're really hot to test, can mail you one or something, lemme know.
