New pm9 feels wierd.

[jocko]

I've

It really does, doesn't it. Seems like that would be visually obvious, the rod would be all sloppy. But I don't see anything else that would contribute to this issue. New one for sure, never heard of a too large guide rod hole.
We need answers here, I hate unsolved puzzles.

seen some holes to big for my guide rod to work right

I stopped reading at page 2 so for give me if I'm repeating stuff. I had the same issue with the slide catching on the guide pin. In my case the cap on the end of the guide pin was hanging on the edge where it goes though the slide.
See pic below

I talked to customer service because this was happening when shooting it. The solution was to make sure the open end of the spring is positioned at 12:00. What I noticed is if it was at 3:00 or 9:00 it would push the guide rod to one side or the other causing the cap to hang on the slide. I also had them send a new guide pin and spring. The spring was way too long but I did use the new pin. It's been flawless ever since.

Wow! This is a new one. I have never bothered to check this. I just take the spring and rod and cram it in place without thinking about it and have never had this happen. But I have had the cap work its way loose and fall off.

yes that looks very familiar and your story makes sense because sometimes my gun would run right for a while after taking apart and replacing. i guess those times i got lucky. but as i said upon shooting it would go back as it was.
well it should be with kahr by now? i will check here directly. maybe they will have a simple fix? yes it does seem as if the hole is too big, almost. i think that they need the extra room so that the pistols off center barrel can function properly(in theory).

I hope they have a solid for sure cure for you. I think we should all make sure they know we're kahrtalk members whenever we send stuff or order stuff. They have got to be wondering where all these knowledgeable people sending stuff in for repair are coming from.
I think you are correct about needing the extra room for the barrel to pivot, I also think that the cure that Bigcube mentioned is a cure as the top of the barrel would most likely be the pivot point and always stay close, that's usually where the wear marks are on the barrel. BUT, I also don't think you should have to install that spring that way to work either. That spring could easily rotate during the firing sequence and roll around to a point where your issues act up again. Anxious to see what they tell you.

Can't say for sure, but you may get a whole new slide and possibly a new barrel and spring assembly.

i would like nothing better than to get a properly functional gun. it would take several hundred rds. with zero issues before i would consider it as a "lone carry".this whole episode has got me seriously thinking about a small, hammerless revolver.

I have read this again and again with nobody taking the cue. I had the same experience with my PM40. I have $100 worth of replacement parts I can't use and had to go back to my old parts to get the gun to operate. T H E --S P R I N G S --A R E --T H E --W R O N G --S I Z E!!! Stop making excuses for the need to compress, etc. If the shorter length and number of coils was good enough for the gun before, functioning okay until the spring got fatigued, it is still the right spring. Don't send me something that takes a team to get it together, only to find it won't shoot.

As far as I can tell, when a Kahr PM model needs a new spring, you have to send it back to Kahr, because they aren't capable of supplying the right parts, and the guns are so temperamental that everything has to be custom fitted by an expert at the factory. Once they work, they're great. All this swapping out parts, when the thing was actually working okay, is a bad idea. My PM40 is going back to Kahr for a complete rework. I bought it used, and it has obviously been used a lot. It has older generation parts in it, so I will let the factory figure out how to upgrade it.

I just tried the other spring. Here is a pic of the 2 side by side

It will fit. It may compress some with use, it is a little over 1/4" longer. I had trouble getting the gun apart with the new spring in it. I needed to rack and dry fire a bunch of times before the slide would come off something was catching on the frame. It was also more difficult to feed the pin though the spring when placing it behind the barrel lug in the slide.

Bigcube,

You may have seen these FAQs at Wolff Gun Springs, and I'm sure at_liberty has.
All things being equal -- wire diameter, type of wire, and size of coils, the most important thing is number of coils. If you lay the two springs side-by-side and orient them the same way, the new spring should be longer. It's going to compress and take a set. That's how they are designed. Look at the Wolff FAQs. They explain this.
In your picture, it appears the right spring has an extra coil... one more than the left. If this extra coil is removed -- not too much -- the spring may work better, BUT I have no idea if the wire diameter and so forth are exactly the same.
We have seen instances where the replacement was too long with several coils too many and Kahr said the spring should have been shortened to the proper number of coils before leaving Kahr, but that you could do that yourself.
I may not know so much, but Wolff designs the darn things and I think that they know what the heck they are talking about. People beat a path to their door for some reason. They are pre-eminent in Gun Spring manufacturing.
This is very good information:

humm. I guess it is how one counts but I count the same amount of coils on each.. All new springs will be longer than used ones.

[wyntrout]

I don't think the bases or the closed ends are perfectly aligned/oriented. It doesn't look like the right one could be too much of a mismatch, being almost the same length.

something tells me that over at the SIG SAUER,XDM OR GLOCK FORUMS that they are not having ,nor ever had ,nor ever will have , this conversation about their ******* GUIDESPRINGS!
#@!*@# KAHR!!!!

Just put it on the block here, don't aggravate yourself. What's the starting bid?

[predestyned]

Gun came back today from KAHR. Here is what the work sheet said:

Action taken:
Inspected gun.Replaced recoil spring assy.Polished parts as needed.Lubed test fired good.


I HAVENT HAD A CHANCE TO SHOOT IT YET . FEELS GOOD. HOPE IT RUNS FLAWLESS .WILL LET YOU KNOW.
