As reported, I lost my Kahr virginity recently to a slightly used P9.
Finally had a chance to devote some range time. Have one seven rd mag with a Lakeline follower plus Pearce pinky rest and one seven rd mag as it came from the factory. Wanted to compare results between the two mags.
The prior owner claimed that the gun had approx. 250 rds shot thru it. The gun was dirty & dry. Cleaned it & lube/greased it before this range trip.
Results:
1) Happy as a clam to report that using 115gr FMJ ammo the gun sent 65 rds downrange without a hiccup of any kind. No need to test hollow points because FMJ is my carry preference.
2) No problems sling-shoting the slide forward using either mag. I did do my best not to ride-the-slide, however. The slide release is a bear to use on my P9 and could easily wear a groove in one's releasing finger.
3) The Lakeline mag follower does indeed do it's job keeping the rounds in line. The stock mag which I stuck into my pocket numerous times did take a top rd nose up attitude and it would have surely popped out given a little more pocket time. Once inserted into the gun, slide dropped, both mags ran flawlessly. Surprisingly, when shooting the stock mag I didn't find the need for an additional pinky rest.
4) I did my best with four rounds to limp-wrist the gun (kinda dangerous to do with such a short barreled lightweight gun) holding on lightly with only the right hand trigger finger and right thumb but the P9 cycled without fail. No more of that.
5) The mag release is too light for my taste. It needs a stiffer spring or bigger internal catch I think. One of the holsters that I have covers the trigger guard completely and the mag release. On two occasions the mag popped out from just the pressure of the holster -- not good! Another holster which does not cover the mag release didn't cause any problems. Is the light mag release a generic issue with Kahr P9s?
6) Accuracy was extremely good. I could hold a quite small group when concentrating. Shot from approx. 8 yrds -- a defensive range. The trigger system was easy to use. I have semi-auto and revolver experience so no big deal adjusting to the Kahr. I did try a couple of quick double taps and that will require more practice on my part because I got the shots off but the second shots were way off the group.
Conclusion: so far so good. Reliable light weight package that needs a mag release tweak. Will strip it down for a fluff & buff, install the second Lakeline mag follower, and take it back to the range for more fun. I like it!
