last week both my newly acquired Norinco Sig clones (NP22 & NP34) arrived and after a good cleaning then lube i put them into storage for a day when i have time to go to the range. today i took them both to try out. shot 20 rounds of 115gr. Blazer Brass through the NP22 and it functioned flawlessly (Except for the less than stelar double action trigger). i then loaded up 20 rounds into my NP34 and fired the first round. the pistol jumped quite a bit more in my hand; probably due to the fact the NP22 has the norinco grips replaced with p226 grips and the NP34 has the slick stock grips still on it ( P229 grips are in the mail for it). anyway, after the first round each round after would fail to put the pistol into battery and would need a light push on the slide to lock it and allow it to fire.

has anybody experienced an issue like this? is this normal as the pistol breaks in? any suggestions on how to fix it?
 
Will a round drop in the chamber with the barrel removed from slide?

Did you clean it as in is there a bunch crap in the way?

My best guess is going to be the extractor
 
it was covered in a thick greasy oil like every chinese gun i've ever bought. I wiped it down with isopropyl to remove the packing grease then with a thin coat of gun oil to prevent rust and some grease on the slide rails so it slides nicely. A round drops into the chamber nicely as well.
 
Can you disassemble it and post some pics?

I have had my NP34 for a few years and it has never missed a beat.

Added Hogue grips and a SRT trigger kit.
 
Just disassembled the pistol, the slide was really difficult to remove, it would move on the rails fine but felt like the slide was getting caught on the takedown lever. After a bit of trying it did come off and i found some weird wear marks on the takedown lever that looked like the twisted pattern of the recoil spring. After looking at the spring and guide, I found the spring had ridden up over the end of the spring guide. I took the spring off of the guide and found it has a very slight taper on it, im assuming the wider end is to sit against the slide and the narrow end sits on the lip of the spring guide. The end that was towards the locking insert is wider than the other end; this allowed it to pop over the flared end and get caught between the two pieces when the spring compresses. Flipped the spring around the way it should be so it cant do that again and it seems to be fine. We will see how it runs next time i'm at the range. I will also try different ammo to see if it just doesn't like blazer.

When I cleaned the pistol initially I left the spring on the guide and just wiped it down with a cloth. Didn't think twice to look at the spring closely because every other pistol I own the spring is reversible. Really shows you to closely look over Chinese guns for minor quality issues before you shoot them.

Since the grips are really slippery, it could be that the gun is moving around in my hand and absorbing just enough recoil energy to stop it from locking as if I was limp wristing it. As I said in the original post sig p229 polymer grips are on their way and should help the problem a bit.

I have exactly the same experience, lol 1. never missed a beat, 2. Hogue grips and 3. SRT
NP 34 is a great bargain given what you pay and what you get

PS. Limp wristing could cause this for sure (I saw it happened a few times when my 9 years old was shooting it. But it was the same thing with glock 19 - basically the kid wasn't strong enough to handle the recoil)
 
You would have to have some tiny girly hands/wrist to limp wrist a gun to no go into battery....

Recoil spring or extractor I only say that because I had a 226 and the extractor was to tight and would slow it down just enough that it wouldn't go into battery. Recoil spring because I've seen them get jammed up all to hell and back and cause all kinds of stupid problems

This is how it is in real Sigs.
