Break-in question

[mpgo4th]

On the very first fired round in my new cm9, the slide failed to remove the spent brass completely and hung up. I racked the slide and fired 50 rounds trouble free. I've run 115, 124 and 147 JHP as well as cheap and expensive fmj just rounds with no problems. I'm over 100 rounds now and have had zero problems since the very first round. I feel that this gun is good to go for carry and I trust it 100%. I keep reading about people and watching videos on YouTube about people needing to run 2 or 3 or even 500 rounds before they feel it's ready for self defense. Maybe I'm wrong but two 50 round boxes using three mags and I can't think of any reason not to trust it. Not really a question just wondering how everyone else feels about it.

Your going to shoot it anyway right????????????????? Then the 200 rd. count is meaningless. Just for giggles, shoot the other 100 rds. You'll thank me later.......................................

Many folks are completely comfy after 1 box, I know some that don't even shoot that much and figure they are good to go.
It's all about your confidence, not anyone elses. I'm one of those guys that wants 500 perfect rounds or we start over and figure out what's up. That has actually reduced some due to ammo cost and time constraints but I shoot as much as I can until I know it runs.

Course Murphy follows me around like a pet project so I may be more concerned than others.

I think your probably good to go but as beretta said, sure don't hurt to put another 100 through it when you can.

Of course I'm going to continue to shoot it. That's what I do with all of my guns. Any carry gun I own gets shot like a range gun too. Maybe more. I was only pointing out that I'm comfortable with mine already as some are never really satisfied. In no way was I implying that it's good to go and now I'll just carry it forever without shooting it again.

Your thinking good. You'd be surprised how many folks never or hardly ever shoot their carry guns.

Usually when I go to the range the carry guns are shot first. I don't do anything to prep them, just shoot them the way they been carried since the last trip. Use the ammo in the carry mags.
Then shoot practice ammo and reload with good stuff for the ride home and the forthcoming cleaning.

Go forth with confidence, your plan is sound.

It's probably not scientific, but I feel a lot better about guns that work 100% with the first 20 rounds or so. I expect to have problems with any new firearm, so I'm never surprised with problems until after I've shot 200 or so rounds through them. In my experience, if a pistol does 100% with the first 2 or 3 magazines, it's very unlikely it will not show any addition problems with the next 200 rounds or so. If it stumbles occasionally with the first couple of magazine, it's likely it will have the occasion problem through the first 200 rounds or so.

The catch is, of course, that even after firing the "break in rounds", whatever that count is, we still have to consider what we're actually going to carry. I usually fire 200 FMJ rounds through anything I plan to carry before trying out my carry ammo.....but I do not fire another 200 rounds of that super-expensive stuff to continue the "break in"! I'll fire at least 20 of those SD rounds unless that particular gun seems to have problems during those 20 rounds.....then it's time for a decision. Having said that, I have not yet had a pistol that completed the "break in" of at least 200 rounds that failed to function (within 20 rounds) my chosen carry ammo. Of course, I am using pretty standard carry ammo; no weight bullet weights, no super unusual bullet type, etc, etc.

I'm not into counting rounds before I'm OK with a new gun. I carry the gun when I'm comfortable, confident and competent with it. That usually takes a couple hundred rounds at least anyway. I carried my Seecamp after maybe three mags. It all depends on the gun. I'd carry any HK with no practice, (although I would anyway). Depends on the gun, depends on how I feel I can shoot it... the three "C"s.

I agree with you totally. I the few problem children I've had always acted up in the first 20 or so rounds. Some got better with break-in, some did not. Only once did I give up on a gun. The manufacturer actually replaced it and the new one was worse. Not to start a brand debate but I no longer buy, own or recommend their.

I tend to be the same way.

Ah come on, give us a hint!

200 trouble free rounds and I felt good to carry. I have gone to the range monthly and shot 50 rounds out of both of my carry guns, a PM9 and a CW380. I do some dry fire practice with both guns on a regular basis and feel that you still need to fire live rounds on a monthly basis. To buy a gun and stick it in your pocket without regular practice is foolish. JMO

From what I've seen, there are many people who have never fired their carry firearm...................................which is a very scary thing.................

[mpgo4th]

It rhymes with Morris

Morris? Have to think on that a while.......I can think of one toward the end of the alphabet.....

Even though dustnchips goes beyond break-in, that is what I would consider both the minimum and adequate regimen.

Since I am new to Kahr Talk I will give some background.

The second time I fired a handgun I qualified as Expert in Navy boot camp. The first time was when I was 5 years old and my grandfather held his hands around mine while I pulled the trigger on a little Smith 38 Special revolver.

Since then I have reloaded and fired in various disciplines (IPSC, NRA Handgun Silhouette, local bowling pin matches etc.) something on the order of 30,000 rounds of handgun ammunition and another 10,000 rounds of centerfire rifle ammunition. I have also fired around 10,000 rounds of rimfire rifle ammunition, 3,000 in the last four months.

I knew very little about Kahrs until a few weeks ago when I decided to acquire a readily concealable handgun. I did some reading and settled on a Kahr, either a P380 or PM9. After seeing a CM9 in a LGS I decided that the PM9 was small enough to comfortably conceal with light summer clothing. While I would have been confident with a 380, I am happy that I found a serviceable 9mm.

I may still end up getting a P380. We'll see.
