kahr pm45 problems

captbahbah · 10-22-2010, 06:32 PM

Hi to All. Put 200 rounds through the gun: 50 rounds of Independence 230 grain ball, 50 rounds Of Magtech 230 grain ball, 100 rounds of Winchester 185 grain Brass Enclosed Base. Used both hands, RH only, LH only. One- shot drills, two-shot drills, five-shot drills, rapid and controlled shots at 50 feet, 21 feet and 7 feet. Head shots too. 3 failure to feed due to limp wrist. Other than that, no malfunctions. Gun is accurate. Recoil is snappy but manageable. Follow-up shots no problem. Pinky pinched at bottom of magazine and magazine well. Brass hit my forehead and face a handful of times. Called Kahr. They said it was my grip. Factory sights: front dot, rear notch. Will be putting on XS Big Dot like I had on my MK40. The slide rides on plastic rails! Called Kahr didn't really understand the explanation. Will have to inquire again. It works, though. I like the gun. Small size, big bore. I have a Glock 30. Big gun. I usually carry my S&W Bodyguard or Colt D/S. I just prefer revolvers. This gun may be just what I'm looking for.

Glad you like it. Kahrs are like S&W autos to me. Point too low, have to make an effort to keep muzzle up. 1911s,Glocks, SIGS all point naturally for me. So do my revolvers.

Limp wrist can cause failures. Brass hitting your face, well, more knowing people than me can answer but its more of an extractor/ejector problem. Frame rails can't be all plastic. Have to have steel inserts like all do. Even your G30.
Enjoy it.

Thanks. Extractor/ejector was my first thought also. I'll see. My next range session will make sure of my grip. If it still happens, I'll know. I suspect it can be an extractor/ejector problem. Was doing dry-drills with brass dummy rounds. With a round in the chamber, I rack the slide to feed the next round. When I do this, the round that was in the chamber does eject but the new round gets stuck inside the chamber and had to use a rubber mallet to move the slide enough to get that round out. Had to do this several times. Recoil spring problem, too? What a bummer. I really want this to be THE gun for me.

Sometimes hand cycling slows down the process enough to gum up the works. Actual live firing may not show the problem. If spent cases are not traveling the optimum 4-6ft behind/side then ejector angle, length or extractor could be the problem. On a new gun I doubt the recoil spring would.

Got back on the phone with Kahr. Gun designed so that trigger won't reset usless it is released after being pulled. Advised to use snap caps instead of brass dummy rounds for dry drills. Designed to function via recoil. Advised to run more rounds through the gun and the problem of brass hitting forehead, face should resolve itself. Can administratively unload with no problem. Will updated after next range session.

Please do.

Hi to All. Put 50 rds of Speer Lawman 230 grn TMJ through my pm45. Accurate. Three failure to feed. Two shell casings hit my face. To be continued.

captbahbah · 11-10-2010, 06:23 PM

I'm bummed out. After a total of 530 rounds, over 50 shell casings have struck my forehead a/o face. Suffered two small cuts on my forehead. Also, several slide locks, and failures to feed. Going back to my Glock 30 for now. Can't wait for them to get it fixed.

Thanks for the update.

Got my pm45 back from Kahr today. The Technical Service Work Sheet reads as follows: "Replaced trigger bar. (The trigger resets now when I rack the slide with the trigger depressed during dry drills. Why was I told Kahr made the gun's trigger so that it wouldn't reset when depressed while the slide is racked? Did they misunderstand my problem)? Replaced slide stop spring. Replaced recoil spring. Polished feed ramp. Polished slide stop. Polished ejector. Lubed. Test fired. Good." Promptly fired 100 rounds of 230 grain ball ammo. Still very accurate. Total of 34 shell casings still came back to hit my forehead/pate/right eyebrow. Had another person fire 10 rounds through the gun and he didn't have that problem. Maybe it is my grip. For some reason it still won't admin unload Federal 230 grn Non Toxic ball rounds but will with Federal 230 grn ball. Not too happy. Am going to put more rounds through the gun and report back.
