I'm the new owner of a Kahr PM45, here is my 1st impressions / experiences.
Recoil is not bad, less than the PM40. I shot 140 rounds today with no discomfort to my hand.
I cleaned the pistol prior to shooting, as per owners manual.
Chronological details of shooting:
-10 rounds Remington 185 JHP, no problem.
-20 rounds Fed. 185 JHP, 4 failures to feed (bullet about 1/2 way in chamber, corrected by tapping back of slide).
-25 rounds Fed. 230 gr. HS, no problem.
-40 rounds Rem 185 JHP, no problem.
-15 rounds Fed. 230 HS, no problem.
-30 Fed. 185 JHP, 1 failure to feed.
The Fed. 185 JHP is the only ammo that I had a problem with during the 1st 140 rounds, it has an agressive hollow point design (seen in pic.) compared to the other two loads which look more rounded.
I already feel comfortable with the 230 HS or the Rem. 185, since they worked without a problem, even though I have not completed the recommended 200 round break in.
Chrono results, 5 shot average:
-Fed 230 HS @ 781 fps
-Fed 185 JHP @ 856 fps
-Rem. 185 JHP @ 889 fps
Summary: I thought I might have a problem with recoil, especially with 230 gr. bullets, but it ain't so. Based on two out of three loads tried during the "break in" I'm thinking the PM45 is going to work just fine. I'm planning on carrying it frequently after I get a holster.
I did all my shooting at 7 yards. The last 25 rounds I decided to shoot slow fire (two hand hold, no rest) with the Fed 185 JHP. I was able to put all 25 rounds into 2.5'' at 7 yards, which I thought was acceptable for a compact, lightweight 45acp.
Here's some comparison pics. with the PM45, PM40, and Glock 36.
