PM9 - Ultimate break-in procedure?

[Scooter70]

As I said in my other thread, my PM9 (LDC w/NS) should be here soon. BTW, Jerry at Ordnance Outsellers is a great guy to deal with! I've read through this entire forum and have already gained a wealth of knowledge from you guys. Based on everything that I read, I decided to buy a brand new gun just in case I needed to take advantage of the lifetime warranty.

Anyway, my question is this: What do you feel is the ultimate break-in procedure for a new polymer Kahr? Other than a thorough cleaning and then putting 200 rounds through it, what else can I do to ensure proper operation? I've read that some people polished the feed ramp before they even fired the gun for the first time. Is this a good idea (based on past precidence) or is it overkill until I experience an FTB? Those of you who have perfect PM9s, is there anything that you did to make it that way or is it just luck?

The archives at GlockTalk don't seem to go back very far, so hopefully we can get some good discussion going to help others with new polymer Kahrs in the future.

Thanks,
Matt

Clean it, leave it a little wetter with oil than you would most guns. Shoot 100 rds, clean and oil it again, shoot another 100. May take a few more than that to get it 100% but once they are, it's a great CCW pistol and very accurate as well. If you still have problems with full return to battery, call Dottie at Kahr customer service and tell her you need a new recoil spring assembly. She'll try to tell you that's not the problem, but trust me, it is. The newer ones have a longer external spring and will take the gun back to full battery every time. I've had two of these guns, one a black stainless that took almost 500 rds to get to 100%. I sold that one but wish I hadn't. I carry a stainless slide model that I can't make jam, even limp wristing on purpose.

I'd clean it and shoot MORE than 200 rounds before calling it good. I believe my PM9 took more tha 200 rounds to be fully broken in. I wouldn't modify or polish anything just yet. I like to see how things perform in factory stock form and then evaluate. Polishing the feed ramp is simple though.

Shoot the heck out of it without cleaning. I'd recommend a light metal polish used on the barrel surface. Looks good too.

Mine's been perfect, all I did was clean and lube it thoroughly, then took it out and shot close to 400 rounds thorugh it without cleaning (added a little oil to the rails intermittently though).

Howdy:

Prior to my Kahr PM 9mm break-in period, I lubed my weapon (VA #59XX) with Microlon (www.microlon.com) a dry lubricant I've used for years. After 200 break-in rounds without any malfunctions I got bored because I was expecting problems. During my next outing, in the 350 round range, again bored, I limp-wristed my weapon on purpose and had several FTF (failure to feed) malfunctions. These are the only failures I had and they were self-induced!! My weapon is 100% reliable!

have the issues with the plastic Kahrs been dealt with?


it was my understanding that it was a toss up with reliabilty on barrel peening and other issues that are specific to the P9 and PM9.....
