Kahr PM9 Break in issue

[1911Tuner]

A recommended break-in period in order to get the gun to function is a myth and a misleading notion. It shouldn't be required. It's a machine. If it's built correctly, it'll run. It doesn't have a choice.

Send it back.

Kahr

factory technician I worked with when my PM 9 was at the magical 400 round break-in and mine was getting worse instead of getting better and with light strikes being the end all said this...."the PM 9 should run any quality manufactured ammunition regardless of JHP nose configuration".

I tend to agree with Larry Seecamp (I am paraphrasing) who says break-in on a handgun is bunk. It should wear out with time, (the rest of the analogy is mine) not get better with age as in a good single malt.

What's the update??

I wanna be clear at the outset that i follow 1911Tuner's posts like religion on this board, so (gulp) am loath to even whisper to the contrary, but i've certainly had my share of all types of autos where it took a good couple hundred rounds for things like the slide stop to be smooth and workable with just the thumb of the shooting hand, or the mag release to be an easy shooting thumb press for a release. they're not only machines, they are machined. and (teaching fish to swim here i know) that machining is done to a spec that has a tolerance so (example only) a spec might say .001 to .004 mm gap between slide and rail. a quality machine job will be done to the tightest tolerance the spec permits taking for granted that over time, operation will work it back to the other side of the spec and...as you say...eventually deteriorate beyond the acceptable parameters of the spec. back in my days as a ground pounder in Uncle Sam's Maintenance Crew, we used to run from new 1911 'cuz the inevitable sand and dirt would jam them. in those days, a little rattle twixt slide and frame meant a gun was "good to go"....nowadays, when i'm spending $1k or close to it for a gun, and have grown a bit to old to be crawling in as much dirt and sand as i used to, i want my guns machined nice and tight.

to 420, we're not talking about "flinging" here, if you look at the pics vsix posted you'll see we're talking about the ability to get the round out of the ejection port *AT ALL* as its jamming b/n the back end of the barrel/feed ramp and the back of the chamber/striker housing

I can't tell anything about whether or not the round could clear the port from that picture. All I can tell is that it is in the upright position and there is a round beneath it. The wording in the OP post suggests that he would expect a loaded cartridge to clear the weapon by racking the slide as if to load an empty chamber. I was just pointing out that I would not expect the round to clear in that position and was asking if I should.

I can't say that I've tried it often, but I have the feeling many, if not most, pistols will jam if you retract and release the slide with a loaded round in the upright position and have another round following in the magazine. If you don't take some action by tilting the gun, or by removing the magazine and allowing the round to fall out of the mag well, there is no place left for it to go.

i would call kahr. the polymer models seem to have the issues, my steel framed model k-40 and all the ones that i have shot in the past have been excellent i don't know what is up with kahr and there ploymer models.

loath to even whisper to the contrary,

Hey! Don't whisper. If it worked...shout. It's not that sometimes a couple hundred rounds doesn't improve one, and it's not like it never, ever works. Nothing "never" or "always" does anything.

It's just that, if we keep accepting this sort of thing, there's no reason for the manufacturers to take the necessary steps to effect an overall product improvement...and we keep throwing our money at guns that are assumed to be OUR responsibility for makin'em work. The notion of burnin' up a half case or more of what is gettin' to be expensive ammunition...in hopes that it'll straighten out a problem that shouldn't have been a problem...is a bit unrealistic. With the CNC machining in today's gun industry, there's no reason that we can't have the best firearms that we've ever had...but it seems to be headed in the other direction.

My para

My para carry nine was not good at first but after about 200+ rounds, it was flawless. I could live with that, very few auto's do u buy where they just tell you to drive it like you stole it and instead of being alittle gently with it for x number of miles. Call it break in or range time. My kahr didn't need any break in at all, I just figured kahr and many other mfg-ers use the x number of rounds for break in to possably avoid one sending it back with 20 rounds through it etc . Might be wrong there also.

Most all of the polymer kahrs today were excellent.
