PM9 Trigger question

[doctorxring]

.

I just got a new PM9. The trigger feels different than
my P40 Covert and my P380. Not as smooth. I can
feel a little "wash boarding" as the striker spring
compresses on the trigger stroke, which I don't like.
Not the glass smooth stroke of my other polymer Kahr's.

Should I just go ahead and call Kahr and send this
pistol back, or is this something that can possibly work
out with shooting it ?

thanks, Chris

If I was you I'd shoot it. First I'd go to the tech section and read the prepping your new Kahr thread if you haven't already. Also check out the lube chart in the same place.
Racking the slide and pulling the trigger before the first range session might just smooth it right out.
If not a trip back can always be done later. I think it will get better.

I'm with Junior. Prep it right, rack it as much as your hand can handle, shoot it like you stole it, rinse, repeat. It should smooth out for you.

kahr, they wil ltell you what the forum just did. shoot it a few hundred rounds. They won't take it back for what you might feel is different than the other kahrs you own.

Now maybe if you want to , you can take the upper slide apart and with some fine 600+ grip auto paper smooth everything that moves and check for any burrs etc. That trigger bar and that trigger bar return spring is more likely your culprit You can see that buy looking down inside the grip ont he right side of the grip. U can if you feel like it with a #6 torx tool take that side plate off and again with some 600+ grip paper smooth that trigger bar up where the little spring rides along that triger bar, Also put a dab of grease right there where the spring and trigger bar sits in the spring slot. a drop of olil in the trigger area won'thurt anything either..

MORE ROUNDS DOWN RANGE WILL CLEAR UP THINGS ALSO..

Ditto all said so far ...
Plus, Make sure you're not dragging your finger excessively on the trigger guard as you squeeze the trigger ... it'll feel exactly as you describe. ;)

Thanks for these comments !

I took the slide off and the trigger pull is dead smooth with the slide off
when operating the trigger in the frame.
Could it still be the trigger bar/return spring ?

thanks, Chris

I'd say probably not. It's dragging up in the striker area someplace which is really really good. You can get into that area with little risk if needed. Either take it apart or blow out the striker channel with brake cleaner or gun scrubber and see if that helps. Sometimes debri gets left behind but I hear of that less and less. Mine were both squeaky clean new.
Personally I'd stay out of that trigger bar and spring area and not touch that screw that holds that plate on. Too easy to mess up the threads.
It should still get better just with shooting.

likely NO, u have already eliminated one possability, so I would venture to say it is in the striker assembly. very easy to dissamble, there are threads on taking tghe slide apart. follow closely and you willnot loose any parts. I think I would go with Bawanna stated first to see. Get a sgood spray cleaner and that little hole on the bottom of the slide up by the breech face feeds directly into that striker channel just spray the heh out of it and then with the nozzle in the hole pull back ont he striker itself and that even opens that front area up more, fluids willcome out the back and the breech hole. this willclean that channel up perfectly, and now see how it feels. . If it doeksnt help, you might have some fuffness in the striker channel area that with some rolledup 600+ grip paper will smooth it out OK with no damage to the slide. The less you mess witht he right side back plate the better you are for ure. There realy is no nee dto take that palte off other than what I suggested might be ur issue, which is evident it is not in that area. You might also witht he slide off and very slowly working that striker back see if youcan feel any washboarding..

Well I got home from work today and took the slide off
the frame again. I have isolated the source of the "feeling"
I am experiencing. With the slide removed and laying in
my hand, when I compress the striker spring by pushing
on the striker sear with a screw driver I can feel the spring
compressing. The striker is sliding smoothly in the cut
in the slide, the vibes are coming from the spring somehow.
I'm not totally fluent in this design, but I would bet a dollar
to a donut it's the unsupported end of the spring rubbing
in the hollow of the striker assembly somehow. I don't
see how this could smooth out by wear. This a bind of
some kind going on here.

I took my P40 Covert slide off and compared. I cannot
feel the spring compressing, only the striker housing
sliding back and forth in the slide.

I'd have to agree with what the guys are telling you. Prep it. Shoot it. Be patient and give it a chance to smooth out. If it is still a problem, you have a 5 yr warranty.

I agree Gary. I'm going to shoot it this afternoon. It's not anything
that really impairs the pistol, it's just not the usual Kahr refinement.
I'd bet there are a number of Kahrs running around being used with
the trigger running just like the one on my PM9 and the owners never
knows the difference, thinking that it is normal. In isolation from
other Kahr pistols, you would think that. I've fired 5 Kahr pistols
now and this one is the oddball.

I ordered some new striker springs, a standard and a 5 lb version
from Wolff. When they come in, I'll strip the slide down,
look it over, and try a spring change. If it's still binding, I'll call
Kahr and talk it over with them.

I'll post any resolutions on this thread. Thanks to ALL who came in
on this issue. One good thing from this issue is that I really learned
the details of how this pistol operates. I feel certain that it can be
resolved with just a part change or two.

good shooting, Chris

doctorxring:

I like that "wash boarding" term, a very exact descriptive term, better than gritty.
If you ever have all those trigger parts out I suggest you buff all the obvious sliding surfaces.
I have found, with a 1 inch buffing wheel in a dremel type tool, it is very difficult to screw up anything.
I spin it up inside an open grocery bag and apply some nu finish car wax to the buffing wheel, as it has a mild abrasive in it.
The bag keeps it from striping my wall!!
Be aware of the wheel turning direction so it dosen't grab on the sharpe edges and just buff the sliding surfaces.
Go for shiny, not smooth, straight or flat and you will be amazed at the improvement.
just sayin'

the bag thing is a damn good suggestion. I have spend some good timeon the floor looking for small parts that my dremel tool caught and pitched..
