CM9 bbl. in a PM9

[BEARDOG]

Just another point to this, I remember a few months ago we went through this same thing over slide stops, Kahr said the MIM was different then the machined and would NOT interchange....Then a few members chimmed in and said that was B.S. They have done it and it worked fine.

That said I wouldn't drop $140 on a barrel either that the manufacturer flat out tells me won't work. But if i had a PM9 and a CM9 available I would bet they would swap just fine

Here is a interesting ammo velocity comparison from Jeff Quinn with a CW45 and a P45 as you can see he found that the standard rifling in the CW45 was slightly FASTER! ??? Go about half way down to the chart.

OK. That's the second actual test report that we've had on the forum saying the conventionally rifled barrels shoot bullets faster than the polygonal barrels in these Kahrs.

I can't say this "officially" but I have it on high trusted authority that if your PM and CM are both new models the barrels will in fact interchange.
If your PM is the old style or what we call the blunt nose it would be shorter and would not work.

Bawanna;

Possibly your "high trusted authority" can "officially" contact Jay @ Kahr Arms and explain to him why the CM9 bbl. will interchange with the new model PM9, which I have.

Any follow up on this?

Can two users, one CM, one PM post some shot of barrels? This isn't making sense to me, unless its the part upper inside corners of the slide that are different radii perhaps?

If they do it isn't much. 10ft/sec = 6.8mph. You can run faster than the difference. Doesn't really matter in a SD gun. You point it, pull the trigger, it goes bang and the BG is slowed down. He won't care much if it's 7mph faster or slower.

I had forgotten all about this one, thanks for reminding me.

I haven't been contacted by Jay or anyone else at Kahr Arms advising me that a "high trusted authority" has told them that the two barrels will safely interchange.

End of dicussion! The only diff between the PM9 and CM9 is cosmetic and accessory options. The CM9 is not some cheapened product, like a Kel-Tec posing as a Kahr. It is a bargain PM9!

thank you, I knew u were good for something. I need tomake note of that in case I need ur help again. Thank u.

Nuff said... and nuff seen. You can get enough views of the inside of the CM9 slide to observe the shape, and the quality with which the metal was cut.

Good job

yes indeed JFOOTIN has found his nich in life, he gets my vote for THE MAN OF THE MINUTE REWARD"

bot any longer thanb that though, .This was a heavy debated topic awhile back with nobody believing anybody,but I think this video puts that topoic to a nice resting place.

CM9 bbl. in a PM9

There are actually 2 videos on this out on YouTube. Pretty interesting...

He wants to sell his unused CM9 barrel for $75 (a couple of weeks ago) becuse the PM9 barrel in the CM9 was working great for him.

Here are the Youtube links:
