Crushed striker block spring

[jt.ipa]

I searched and couldn't find anything on this problem. While dry firing my CM9 the sound of the striker became muffled all of the sudden. When I stripped the slide I found the striker block to be stuck in the depressed position and when I removed it the spring was completely crushed.



I ordered a new spring but I'm curious what may have caused this. Perhaps it wasn't seated properly from the last time the slide was reassembled? I keep my guns clean and I have between 500 and 1,000 rounds through this all stock two and a half year old pistol with 0 malfunctions. Thanks.

Sure never seen nothing like that before. I can't see how the heck it could have happened.

Just curious, what exactly did you disassemble? Did you mean a basic disassembly or did you remove the Striker. If the latter it seems maybe it wasn't reassembled correctly.

[jt.ipa]

The striker has been removed in the past (detail strip) and I would tend to agree with you that it must not have been reassembled correctly. Exactly how it was incorrectly reassembled I do not know because it's a fairly straight forward process.

[Bawanna]

And this is the striker block spring, not the striker spring itself which is on a guide rod?

I'm baffled.

[jt.ipa]

That's correct, the striker block spring is what got crushed, everything else is fine. I guess the lesson here is be careful if you mess with it.

I'm leaning toward assembly error though not necessarily your fault. Doo doo happens. At least you broke an inexpensive part.

You should always test the striker block for proper operation before putting the slide back on the frame. It should spring out when you depress and release it... and it should keep the striker from going forward until depressed.

I have a lot of spare parts, but probably not one of those springs... tiny and easy to lose!

I dunno how it could be mis-assembled, yet work for a while, then fail. I cannot imagine the orientation of the parts that would allow that. I can see the spring being all stretched to one side or such and failing, but not working ever.

Could this be a crud issue?

And I ageee, in the time I've been visiting KahrTalk, I have no recall of this issue

[Bawanna]

Something just ain't right. It's a simple little hole with a simple little spring, I can't see anything to bugger up that spring like that.

If there was crud in there it would be obvious and I doubt anyone would ignore it.

I seldom take mine down that far. I do the rattle test each cleaning. I depress that striker block and shake the slide to hear the striker moving back and forth, if it rattles good to go, if not you got crud to clean out.
I do this even more with Glocks.

I'm just not grasping this. You sure your dog didn't get hold of it an chew up, that ain't likely, it's so small he would of swallad it.

I shall continue pondering. Might tear mine down again to see if a light bulb goes off, I am usually a bit dim though so probably won't be much help.

It looks like the spring was dislodged during reassembly and crushed by the block. Try dipping the bottom of the spring (end that goes into the block) in a slight bit of gun oil, CLP, etc when placing it in the block; it will help hold it in place as well as provide a bit of lube for the spring channel. If I recall correctly, both ends of that spring are closed and it wouldn't matter which end goes in the channel...

After slide assembly, function test the block before replacing the slide. Push the rear of the striker forward, the pin should not protrude from the breach face, then press the striker block and push the striker forward again to see the pin IS protruding and lastly, push it one more time with the block released to assure the pin is not protruding.
