About a year ago, I picked up and held a Kahr P45.....and I knew at some point, I would own one. The grip and compact size seemed like it would make the perfect carry gun. After shooting it, I am definately in love with this little cannon.
I ended up trading a standard Kimber Pro Carry towards the Kahr. It was bittersweet, but also having a Pro TLE to keep in the stable lessened the sting somewhat.
I've read alot here (and some other forums) about the issues alot of people have had with their P45's, and after studying the gun and putting a hundred or so rounds through it, I made some observations on the cause of some of those issues. I had only a few mishaps in that first 100 rnds, but I'll share my thoughts:
Before I went to the range, I broke it down, cleaned and lubed it. The fit of slide to the frame is pretty tight, but the chamber and extractor are what caught my attention. I put several rounds into the chamber (with the bbl out of the gun). With the round in, I spun it with my fingers, as if tightening a screw. The fit was pretty close and some rounds would not spin. I also tuckeded a few rounds under the extractor to check the tension. Again very tight. You could tap the slide gently on a bench and that round would stay seated. Combine that with how tall the extractor is, and there is quite a bit friction to seat a round betwen the extractor and the breech face. It's nearly twice as tall as the one in my Kimber Pro TLE.
During my 100 rounds (mostly 230gr ball, with a mag of Hydrashocks thrown in), I had 4 instances where the slide would not go into battery all the way. I think this is largely due to the fit of the extractor and/or the round rubbing against the chamber wall on its way in. I had one FTE on a final round in the mag, where it looked like the case didn't quite make it out of the ejection port. Again appears to be the extractor. I also paid attention to the bullet presentation from the magazine to the chamber. The top round is pointed directly into it and it looks like the feedramp gets very little contact if any during the feed cycle, maybe mostly when there is a nose dive coming off the mag.
While disapointed that even a few failures occured, I do feel these can be overcome during the recommended break in period. I know many here have strong opnions about that, but I'm not going to discuss that here. I had similar issues when I got my Kimbers, but I was able to eliminate all issues with a Wolff high power recoil spring. I checked, but there doesn't seem to be anything available for the P45. I'm willing to bet another lb or two of spring force would eliminate the issues I saw.
Anyone know if high power springs are available for the P45?
As for general impressions shooting the thing, the recoil was pretty manageable, although I'll have to work on my weak hand in the 2 hand hold. I noticed a little extra force was needed to keep it seated over my strong hand. Shots grouped very well at 7 yards and I found the bar and dot sights easy to acquire for sight picture.
The biggest adjustment for me is the trigger. I have done all my training thus far on 1911's and the Kahr's DAO trigger has a looooong pull and a loooong reset. Force was fine, but I found myself using alot more finger to move the trigger back and forth, which initially pushed my shots low and left.
I'm really happy with the P45 and I can't wait to get some leather so I can carry it.
