PM9 non-interchangable barrels/frames

[Atilla]

I realize little guns are neat freaks, I didn't clean it yet from my initial range session, partly to keep track of what parts go in which gun!!!

My CZs on the other hand, don't mind a little (or a lot) of dirt, grease, cosmoline, concrete, ice, choc milk shake, pizza sauce........

[jocko]

they both look like the blunt nose in photo #1. Am I seeing things???

The two dimples and one dimple basically mean nadda. Many today are that way. Why I cannot answer.

Ur gframes are really different, no doubt about that. theyhave cvertainly made somechanges .

How about the photos that u showed here, u snd to Kahr in care of Jay and ask the sae questions ur asking here.

I have an early PM9 VA 45xx and the framelooks identical to yours and the slide has one dimple.

My later PM9 which is also blunt noxe but made about 6 years ago, has the cut out and the one dimple. The barrels like u say are different. Strange but I just never looked at them before, always thinkin the blunt nose PM9 were all identical nad interchangeable, and it is evident they are not. both of my PM9 are flawless also. Mine eqarlyoine was in the barrel recall but I did the polish work myself as that was all that kahr did back then on any barrels that were sent back.

Your photos are excellent, khar should seem um to give u some insight..

both recoil springs in these two kahr shold be identical (same 13 coil count). check that out. Ur early version might still have the 3/8" flat part on the recoilassembly that goes up against the barrellug, where as ur later versionhas the 1/2" soze. kahr made a change about 6 years or so back to the 1/2"size, Whiy I cannot tell u asback thenmy OM9 worked fine with the 3/8" flat part on the recoil assembly, but any new onesthatI bought camein the 1/2" size. Court the outter spring coils. they should be the same coil count. One may belongerthan the utter due to more rounds out of one over the utter but the coils are the same number. U might just reverse recoil assemtply kand see if u can now rack the slide and lock the slide open on the one that u couldnot do before.

U gotta start somewhere to try to eliminate what might be staring u in the face but yet one cannot see it.

Thats a great point, Jocko.

If the recoil spring is mis matched to the barrel 'vintage' ... it could be reaching near the lock up point (of the spring) before the slide reaches the slide stop notch. That would also explain the difficult hand racking

[jocko]

don't confuse what I just said. the 3/8" and 1/2" recoil assebly willwork perfect in any of the kahrs you have. ther should be no difference. Why kahr wkent to the 1/2" size Ican only theory was that mabye that back portion of the recoil outter spring was trying t ride over that 3/" flat peace. It is the outter recoil sprng count that really matters. Both should be 13 coils.

Being my early version is like yours and I did change to the 1/2" size when I ordered a new replacemtn recoil assembly, as they no longer offer the 3/8" size anyways, so either will fit in either gun, just that today all of the older style blunt noxe slides and todays nedw beveled slides hav ethe 1/2" flat back part on the recoil assembly. Confusing I know, as I am probably not saingit right, .

COUNT YOUR COILS first..

and trust me. a new recoil spring is stouter than hell for hand rackings. We have seen some report here that they cannot even getit in the gun. let alone hand rack it or lock the slide open. But after a hudred or so rounds the springs takes its designed set and all is well.

U mighttake both outter springs and sit them on a flat surface and see if there is a height difference. Now take the shorter one and put it in the gun that won'tlock back and retest etc.

OK, here are some pics.

That's a kick in the pants!!...never had an issue with anyone I've dealt with there. It does sound like the recoil spring is too long

FWIW..took mine down and I also have the thicker 2 dimple version.

Differing recoil springs in PM9

Here are my recoil springs, short one with 11 coils on main spring from 2003 model PM9, other one more common 13 coils from 2010 PM9. All I have gotten from Kahr so far is an offer for a new slide lock (or slide lock spring?)> I really don't think they are paying attention, I have never seen anything about PM9s being so different that barrels, frames, and recoil springs are not interchangable. There is NO way the 13 coil spring will work in the 2003 Model.

[CJB]

I'm trying to figure out how the blunt nose slide is there....on both guns.

Jocko, isn't the second dimple to denote the new slide cut for the rear sight?

[jocko]

first 11 coil I have ever seen. It could have beenback then the spring theu use dto put in for what they called their lady jPM9. It had a milder recoil spring

I have a vitage PM9 in the same ear 3 u do and the 13 coil spring will indeed go in the gun. I have no idea how the 11 coil got in ur kahr, It could have been shortened also

If u feel that in ur gun the 13 coil willnot work then buy the 13 coil and cut off a coil at a time and test out. No doubt u can cut off enough to getit to work, andmaybe the gun will function Ok also. That will be ur job to test out. The only kahrs I ever heard of wass the lady P9 which they no longeroffer and it had a sorter recoil spring and more than likely what ur showing is tht spring to.

answer that as I have two pm9 blunt nose, one has onedijple, one has two, both take the new style sights. Why some have two dimples and some one I certainly do not know. I thought also the blunt nose slide version was not in production in 2010 but again Idon't knw that eiher for they still sell the Kahr Black Rose version and it is the blunt nose,

[Atilla]

Jocko,

what about the differing barrels and frame without the cutout for the beefier barrel on the newer PM9? Is your 2003 model the same way (thinner barrel and frame?

I'm still waiting to hear back from Kahr with a more thorough explanation. I really don't like the S&W Shield for pocket carry but am considering trading this 2003 one in on one. The other, newer PM9 is fine.

[jocko]

mine (both_) are just like urs. My 03 model is like yours to a tee that is why I feel the 13 coil will work OK. Sometimes they are a b!tch to get in place but once done and then shooting it a few hundred rounds and it will lock back OK At first it might not, but with +P ammo it will do it. If ur cool with it the 11 coil one, which kahr no longer offers just cut one back to fit and be done with it, ur not gonna hurt the gun. Evidkentley it was working Ok when u got it, and who knows maybe the prior owner cut it back . I really did not know the inside of the frame and barrels were differet until ur photo showed it as I never really laid the gun parts on a table to look at them. There is nuttng wrong with the 03 model because it is different than the newer model really should mean nadda either. My carry PM9 is the new style blunt nose and that is the only gun I carry. The used one I just bought about 6 months ago that was made in 03 ,I just bought it because the price was a steal and it works fine and I use it as my range gun and no reason to carry it when I have the brother PM9 thatI have done alot of cusotm work to it... But both use the same recoil spring set up for me anyhow. In looking aththge photo I think the back flat peace on each assembly lookslike the 1/2"size and if so kthat tells me that 03 model has had a recoil change by someone.

[Atilla]

Just to follow up, Eoin sent me a new mag catch/release on the advise of a gunsmith at Kahr. Surprisingly the mag catch must have held the mags up high enough to make the slide lock much easier, at least when cycling by hand...will see at a range tomorrow how that works out.

Still no way the newer 13 coil recoil spring will fit in the older frame and still allow the slide to lock, and no answers on that as far as replacement parts.
