Would you consider this a malfunction?

[Circle_10]

hi, just registered on here. i had something occur with a taurus 24/7 the other day, i had posted my question regarding this on the general firearms section on the forum i normally frequent - ak-47.net (i'm an AK buff)
i got about a half dozen responses but i thought i'd check here also because of the number of handgun afficianados.
I copied and pasted my oroiginal post since i'm lazy and didn't want to type it out again.

"so what do you think about this?
I was out with my taurus 24/7 in .45 ACP today, now i've put close to 300 rounds through it with no problems, but today i had something strange occur....
So i was shooting, and i emptied a magazine and reloaded it, when i popped the mag back in i found that the locked open slide suddenly closed and chambered a round on it's own without me hitting the slide release or tugging on the rear of the slide. i had never had this happen before, and i noticed that i was holding the pistol at a sort of sideways angle when i reloaded that time
i actually duplicated this several times. it seemed to always happen when i pushed the mag in a certain way while the pistol was tilted sideways....
now i'm going to assume this would be a problem with the slide stop/release?
because i'm pretty sure pistols aren't supposed to chamber rounds on thier own just because they happen to be tilted sideways.
it's a pretty minor problem that only occured under very specific circumstances, but i'll be honest, it actually bothers me quite a bit that the pistol is apparenly capable of chambering a round without requiring a deliberate action by me to do so.
any thoughts? sound like a problem with the slide stop or could it be caused by something else? improper cleaning maybe? (as unlikely as that sounds)
--------------

so does anyone here think this sounds like cause for alarm? the replies i got on AKnet suggested that it does happen if you really are slamming a mag in during a reload. several people said thier glocks and 1911s do it fairly often and one said that his USP does it a lot

BTW overall i like the 24/7, as my copied post said, seems to fit my hand very well (way better then a glock for instance) no jams or anything in a total of 300 rounds (although i have been cleaning it between sessions, so i haven't conducted any kind of "torture test".) the sights are still attached, but i'll probably apply some loctite just in case. accuracy i can't really tell you about because i'm still on a learning curve with shooting .45 acp so most of the accuracy problems are my own fault

Have had a few guns that do that. Not a big deal at all.

I had a pistol that I could make do it when I wanted to. It didn't start out that way, but it developed the feature. I actually kinda liked it. It was one less step I had to take in a reload.

My Makarov does that if I smack it hard enough. Unfortunately, if I smack it that hard, it also tosses a round out the ejection port.

 

[pbhome71]

My Glock 19, and HK USP does that, if I slam the mag in hard enough.

I posted about the same thing happening to my Colt Government XSE .45 a couple of weeks ago and was told to try a different mag.
Seems to happen only with a fully loaded mag.
I would rather release the slide myself but at least it fed and ejected everything properly......drf

There are several things in a 1911 pattern pistol that makes this an uncommon occurance. One is the plunger pressure against the slide stop.

However some other pistol designs do not have a similar setup, so when the enpty magazine is removed the only thing holding the slide stop in the locked position is friction. In that type of pistol premature slide release is common.

Circle 10, yesterday after I read your post I duplicated what happened to you with my other handguns and was able to cause the same thing to happen on every gun I tried only when I forcefully jammed a fully loaded magazine into the grip with the slide release locked open

So I would think you dont have a problem unless all of my guns have the same falure...

Guns tested were a
Ruger .45 P90
H&K P2000 .40 S&W
CZ P-01 9mm
Kahr P9
Colt XSE .45 which I also had the original question about....
I hope this helps.....drf

Asked the same question myself about a Glock a while back, which brand seems especially prone to it. It is as others have said no problem and seems to happen with aggressive mag insertion and non-vertical alignement most easily - it's just the slide stop being disengaged by the force of inserting. I can either make the Glock do it or make it not do it pretty much at will - not that I'd rely on the difference under stress so I always work on slingshotting the slide no matter what. This may be more because I have short thumbs than because I think this method is technically superior to disengaging the slide stop, but hey it works for me.

If you could make IPSC "race guns" do this everytime, you would be elected to the gunsmithing hall of fame on the first ballot!

Actually some pistols are designed to release the slide when a loaded magazine is inserted, but your Taurus isn’t one of them.

Normally, the slide stop locks the slide open after the last shot when a shoulder or ledge on the follower pushes the stop up and into engagement with the slide. When a loaded magazine is inserted the follower no longer pushes on the slide stop.

Over time and use the engagement surfaces between the stop and slide burnish and become smoother. Thereafter if a loaded magazine if forcefully rammed home, the jarring may be enough to cause the slide to release. This I think, is what happened to you. A stronger slide stop spring in your pistol might prevent it from happening, but it will make it harder to deliberately push the stop down with your thumb or finger.

thanks for the responses everyone, it's good to know this is not something to worry about. just wanted be sure as i had not experienced it with any other semi-auto pistols before.

Welcome Circle_10! I have a Taurus PT-92 that does that same thing. For me it's not always when I'm forcefull so much as when my thumb bumps the release when I've pitched the gun too far over to speed up my mag release. I found mine won't do it so much when I make sure that the slide release lever is clean and oiled.

 

[stevelyn]

Smack any of them hard enough and they'll slam shut. It's a slide stop or slide lock. It locks the slide in the open position. It DOES NOT lock it securely.

 

[Glocker]

so do so don't. i would say thats normal on that gun, just remember to keep finger off of triger always remember you can always call the company that makes the gun and ask what questions you have, they will answer your questions.

I've found that my CZ75B does this with fully loaded magazines. Doesn't happen if not full.

The mag body swells a bit and if I ram it home hard enough, It will release the slide. I just learned to not slap it in that hard. A good solid push instead of a whack seems smarter to me anyway.

My FN Forty-Nine did this when new, but stopped after about 1000 rounds. Probably just the mag springs getting a little worn.


No big deal with a modern pistol.
