Cm9 vs pm9

[Joe A.]

Has anyone had the opportunity to test the accuracy between the cm9 and the pm9? I know the pm9 with the polygonal rifling is supposed to be more accurate, just wondering if anyone has had a chance to shoot the 2 side by slide.

I have not shot the two side by side but I can tell you that you would be hard pressed to tell the difference between the two.

Your talking a very short barrel, with a very short sight radius. Both are mechanically the same except for the polygonal barrel.

I any given day I suspect it would be a toss up over which one shoots the best.

Both are reportedly quite accurate for such a small package.

I know it would be impossible for me to be able to tell the difference between the two.

Bingo! Even if there is a difference, it would be unperceivable and shouldn't be a factor in deciding which one to own.

Considering what these guns are for, CC, any small degree improvement in accuracy, if there was any would never be noticed.

y God man, there are millions of standard rifled barrels out there, Far more than polygonal barrels, IMO it is a nice talking sales feature kwhen ur on the utter side of the cunter, nothing more,Some say easier to clean,some say B. S..

every comment above IMO is dead on. Just sayin

Primary considerations when selecting a handgun for self-protection are, in my opinion, reliability, fit, and chambered in a caliber adequate to stop a threat. Accuracy is not a critical concern at the short ranges in which handguns are used for personal protection.

If the gun is so reliable that you would bet your life on it, fits you well so you can operate it proficiently, and is capable of stopping a threat before the threat kills you, the rest doesn't matter much.

After extensive research I can definitively say that the PM9 is exactly 1/1000 of an inch more accurate at 27 feet than the CM9, provided that the shooter does his part. :)

That's the information I was wanting to hear.:cool:

muggsy is right, my gauge isn't that close but I have photos of my one shot groups at 50 yards and it is amazing..

There might be a smidgeon of difference in bullet obfuscation resulting in a smidgeon of difference in gas pressure resulting in a smidgeon difference in muzzle velocity resulting in a smidgeon difference in energy resulting in a smidgeon difference in bullet penetration and or expansion. Hmm, a smidgeon flatter trajectory would translate into a smidgeon better accuracy. Sure glad I've got a PM9! :)

[CharlieR]

Shot my brother's CM9, and don't see any difference between it and my PM9.

[DavidR]

And I always thought PM9 was just Jocko misspelling CM9.

I have and have had many pistols with both barrel types and have never noticed a whit of difference in accuracy in any of them.

+1 And the pm9s are much better lookin as well. ;)

A fella who can't tell the difference is telling us a lot about his shooting ability. It takes a really good shot to wring out that last bit of accuracy in a polygonal barrel.
