Hi all! I have a P99 that I don't shoot often enough. It has probably fewer than 600 rounds through it.

I removed the slide, recoil string, and barrel to see if it needed cleaning before shooting this weekend, and when I reassembled it I must have screwed something up. It won't fully go back into battery, and it won't remove. The slide is stuck on something. It will go from between 1/4 inch forward and 1mm before battery back.

Is there anything I can do or is to the gunsmith with me?

Any advice greatly appreciated!

My answer to computer problems is reboot it.

Do the same with your P99. Field strip it again and check to make sure you have the guide rod in proper place, etc. Here is a decent video you can watch as well.

That was a good video, it showed me what I did wrong. I think I had the spring assembly backward. Yes, I'm a dumbass.

Unfortunately I can't pull the slide off the frame at all. Something is stuck inside.

Thanks for replying, and the video is useful.

Yup, make sure the mag is out, pull the trigger and see if that frees things up, (it likely should) re-field strip the weapon and reassemble...

No luck.

Thanks for responding.

I'm afraid I will break it worse trying to brute force it. I guess it goes to the shop.

Does it look like it could be off the rails on one side? If so some gentle taps with a soft mallet might free it...

nope, rails on the front and back are aligned.

I suspect the spring is caught on something or just misaligned.

I put a few drops of oil around the spring and other openings, maybe if I let it work in it will spring whatever is stuck.

This may not help if the recoil spring is causing it, but try removing the striker assembly. I accidentally put mine back together without the RSA or barrel (I can't remember which) and the striker got caught up on something. Once I removed it, the slide came right off.

EDIT: Forgot to mention that this can be done with the slide still on the frame. I'd recommend locking the slide back to take any spring pressure off the striker assembly and be careful.

That was certainly informative. And it appears you could take out the striker assembly even if you can only get the slide partially back (although I don't know how you'd hold the slide back will doing the removal operation).

It's possible, but takes some dexterity. You can grip over the slide (like you're racking it). Use your thumb to push against the frame enough for the backplate to clear the frame. With your free hand, depress the detent and use your thumb to slide the backplate off a bit. You only need to move it 1/8 in for it not to lock back up on you when you release the detent. Once the backplate is out of place, you can use your free hand to remove it completely.

It sounds complicated, but it's really not that hard once you get the right grip on the pistol.

I didn't know it was possible to assemble the slide with the recoil spring on backwards. That must have taken some force.

The same amount of force will be needed to push the slide back enough to allow you to lower the take down catch.

Update, local gun store got it fixed for a reasonable price ($35 bucks).

Thanks for all the input, folks.

Thanks for the update. Was the recoil spring on backward? Did he tell you how he got the slide off?

don't know

I paid my money, said thanks, and got out of there with what was left of my dignity for doing something so stupid, so I don't know.

ko_kyi,

:) I have been there :)

You are not stupid, but actually very wise.

I recently tackled a gunsmithing chore on a CZ 75. Since it wasn't my carry gun, I decided it was worth the risk. Without going into detail, I messed the job up really bad. I decided I was already in it deep enough, so I ordered new parts and after much much frustration, finally got it right. But then, I wasn't totally convinced it was Ok, so I sent it to a gunsmith for verification. He tuned it some, but said I had done a good job. It should have been a $50 modification. Please don't ask me how much more I spent:eek:. However, I now know how to break down a CZ 75 decocker and put it back together. :)

Fixed the jam

I took my P99 out of the box for the first time yesterday. After cleaning, I did the same mistake, put the spring on backward during assembly. The gun jammed as described.

The slide was stuck, will only move slightly. I finally was able to release the jam by pushing on the spring back into the chamber area. Once the spring was pushed about 3/8 inch in, the slide was released.

I thank you for 2 things:

1. You posted the resolution to my problem - excellent contribution!

2. I'm not the only one who has done it, now I don't feel quite as stupid :)

I haven't looked at this thread in a year, what are the odds that you post and I check the thread on the same day? Whoa.
