P-01 Omega, slide stop hanging up..

[Thebillsman]

Ammo: Winchester 9mm 115g, box of 200 that allowed them to jumble around

This is my third time out and I haven't had an issue yet. However, today was a little different. I fired 200 rounds and had two FTEs and one actual jam on the last round of the day. I don't know if it was the ammo quality or the actual firearm. My prior two outings I used PMC and Blazer with no problems.

It was a little embarrassing.

I posted this a few months ago and most of the responses claimed it was normal but my slide hangs up a little bit on the slide release just before reaching battery. My 75 Compact has no such issue. I also noticed that the back of the round seems to get hung up on the curve at the top of the magazine.

Has anyone has any issues regarding their new P-01 Omega?

Edit: So I just thumb ejected all four of my magazines 10x each and it seems like two are different. Two of the magazines have a a wider opening at the top. The other two are pinched and seem to catch rounds that don't load at a perfect angle. Two mags came with my P-01 and two the Compact. Strange.

Here it is. If you look on the right of each magazine you can see that the mag on the left has a much tighter tolerance. If the round isn't loaded/ejected perfectly straight that lip will catch the round after 5-7 ejections.

The magazine on the right has a much wider exit and had no issues. These are both OEM magazines.

Just tweak the feed lips that are tight. You should be able to slightly bend them out. Take it back out and see if that fixes it.
   That very well could be what's causing your issues.

I file mine.. not bend.  hate to have metal fatigue. and then a break.  when?? SHTF scenario.. that would be really bad. thus the file a little at a time! same concept. just seems safer. to my mind. for whats its worth.

one looks like a 40 mag and one looks like 9mm

one looks like a 40 mag and one looks like 9mm

Looked that way to me, too.

Strangely enough, the mags that came with my SP-01 .40 actually have .40 witness holes on one side and 9mm on the other (and feed both types of ammo).

Interesting.. thanks guys

Alright guys, I'm still having this issue. My slide is getting hung up on my slide stop about a 1/16" before reaching battery. If I push inward on my slide stop it returns to battery smooth, but without the pressure there is a hiccup.

I don't know what to do. Is this a defective slide stop? I don't know if filing it will make a difference or is even safe.

Any input would be greatly appreciated.

What recoil spring weight are you using?

What recoil spring weight are you using?

I have not changed the spring. I believe the OEM spring is 18 or 20lbs?

[rhart]

I was just wondering if a stronger recoil spring would help. It looked to me like the recoil spring wasn't strong enough in your video - acted like a 14# spring. I believe some weak recoil springs (improper temper) have been known to have left the factory a time or two. If you had a spare spring laying around it might be interesting to test it out. At least you would have one variable eliminated.

Sounds like the slide stop is getting hung up on the magazine as the slide returns to battery.  Does this happen without a magazine inserted?  From your pictures above it appears there's some variance in the magazines you're using.  Can you narrow it down to one type?  Trying to eliminate some variables.

It occurs whether the magazine is inserted or not.

Based on your original post, not sure if you've pinpointed this return to battery as the cause of the files to eject or that last round to feed?  Seems unrelated.

I watched the video you linked.  Did the slide but return to battery during live fire?

Offhand I'm thinking either recoil spring/guide rod binding or barrel hood interference on something just before lockup.  I'd be surprised if the force of live fire doesn't slam it into battery.  Might be ammo issues... Winchester white box isn't one of my favorites.

I found that 2 out of the 4 mags did not feed correctly and every 5 rounds would release cockeyed and subsequently jam up the slide.

The slide always returns to battery. It never actually stops a 1/16" short, it just has a hiccup that hasn't happened with any of my other CZs. I just want a smooth return to battery and don't know if its going to take some filing or a new slidestop. If I press inward on the slide stop the slide returns smooth with no issues.
