Uzi Eagle slide self-release

Hi, Uzi Eagle owners,
I have UZI Eagle 40 S&W and at the last shooting my neighbor pointed me to some "abnormal" behavior of my gun. When I insert a new fully loaded magazine "slapping" it in, the slide returns by itself, sending the first cartridge into chamber. When I insert magazine slowly, with no push, it stays in the open position and I have to release the slide. Honestly, I didn't see it as a problem and the gun is shooting well, but this guy - shooting instructor, according to his words - says that it's a defect. I cleaned my gun well after every shooting and this is the only issue I've ever noticed.
Did someone have a similar experience or explanation? I used Winchester cartridges bought in the gun store (not Walmart variety, if it means something).
Advice?
Thanks
Mike
 
Not familiar with Uzi Eagle but there are many guns that will do this. Some Glocks do it some don't. A lot of guys who shoot competition consider it a bonus if the gun will do this.

I would not worry about it.
 
I'd prefer that the gun behaved the same way all the time, regardless.
That is, developing a reloading technique that assumes the slide will drop, which some people do, will catch you out if it doesn't
 
Some pistols will do this when the mag is inserted too sharply.

I would guess that you are starting the mag into the gun then getting a running start at "slapping" the base to seat it. This is jaring the slide stop out of its notch and causing the slide to close.

The good news is it only happens when the mag is fully inserted so it will feed the first round

Its not the perfect reloading technique as you lose control of the mag between when you start it into the gun and when you slap it in. A better method is to start the mag into the well, then just open your palm and drive it in

If that is how you are doing it, then look closely at the slide stop and the corresponding notch in the slide. There might be wear that is letting the parts slip

Tend to agree but most guns which do this do it everytime you slam home the mag with force so it id not hard to train for consistency. If the gun does it it will do it all the time or at least that his been my experience. :eek:

A lot has to do with how you slam it home. Many guns if you lock the slide back and hit the butt/heal of the gun with enough force the slide will drop. If your reloading style mimics this action then your slide will drop on many guns. This is why I don't consider it a defect. YMMV

Glocks seem to do it more than others. On the Glock the recess for the slide stop lever is fairly shallow so it is easily overcome. IIRC the 92FS will also do it with regularity.

So to the OP check the slide stop for wear. If it looks normal I would not stress it. If you know how to detail strip the gun call IMI and see if they will send you a replacement.
 
Agree with the guys.
A lot of IDPA Glockshooters depend on the "auto close" for a fast reload without having to slingshot the slide or find the tiny slide stop. I have heard of them intentionally rounding the engaging surface of the lever to ensure it.

My S&W Plastic M&P will do it reliably, my SA would until I put in a bit stronger recoil spring but does not now. Fortunately it has a prominent slide stop lever lik all 1911 pattern guns. My CZ75 will do it sometimes, which is probably the worst situation, you don't know what to expect on the reload.

A friend's PM&P does it too, but just occasionally the slide will close before a round is in line with the chamber, resulting in no bang but a loud curse.
 
I do have to wonder, if you are jarring the gun so hard it overcomes the engagement notch and spring tension, are you really doing the right thing? And, is it harmless?

What "stops" the mag on your gun? Usually its the mag catch locking in, but slamming the mag in could override this. It could cause damage. Not saying it will, but it might, depending on a number of variables.

Competition shooters do run their guns hard, and if something fails, what's the penalty? Loss of a match?

Have something fail, when you need it in a life & death situation, and it has a much stiffer penalty!

Also, are you certain you aren't doing it? You might be bumping the slide release without realizing it?
