Ive read about people accidentily hitting an "extended" slide lock stop and locking the slide open while firing.. I however do NOT have extended controls on my guns...

Yesterday, I was shooting my g27 after doing a FULL DETAIL strip and clean and every couple of rounds the slide would LOCK open. I quick flip of the slide lock and back in action..

So, here are the details though.. my first inclination was that I must have installed the slide lock stop incorrectly (I do know how to do this and keep the spring wire under the top pin).. Everything fine yet it keeps happening.. (with 2 different mags)

So I go home and figure I will pull the whole thing apart and see what I did...

Sooo while setting up... I remeber.. Hmmm what did I do today different??! Then I realized, I started using a different grip.. I was doing a more severe "thumbs forward and held high up on the frame".. Moreso than I have ever done before and I was doing this on purpose this day as I thought it was a more "correct" way to grip it.

Now I did the same thing with my g19 but had no problems, but the g27 kicks harder..

Is it possible or likely I was hitting the slide lock stop under recoil yet not feeling it?? :dunno:

Thoughts?

If you're absolutely, positively sure you've reinstalled the slide lock properly... then I'd guess it's your thumb.

Try shooting one handed, where the thumb is strongly resting on the thumb rest. Or shoot two handed but extend both your thumbs away from the gun (perpendicular to gun if possible). Don't worry about hitting the target or anything because you're not doing this to test for accuracy or control, but to determine if it's the thumb that's in the way.

Do you have one of those high fingers on the side type of grips. :whistling:

I complain to shooters all the time about these competition shooting grips. They can cause malfunctions. Learn a classic weaver grip, or shoot one handed and see if it helps.

Not that high :supergrin: But where the lower finger is applying pressure upwards so they could be "pushing" up under recoil.

I will try the issue of shooting one handed to avoid the issue and confirm the problem.

That's a very common problem with that grip technique. You will learn to adjust slightly so you don't hit the stop or you will revert back to a standard grip. It's just something you'll have to work on and practice.

I'm old and cranky.

I think the both thumbs high and forward grip is stupid. Too much chance of hitting buttons you don't want to hit, or interfering with your slide.

Go back to your old grip

The interesting thing is that "more correct" comment. It's funny to see people quickly copy the latest fads. Not funny ha, ha. But funny as in, interesting.

You gotta go with what works for you, and be confident enough to buck the fad!

The only way to tell for sure is to videotape yourself. I know it sounds weird, but it will probably help your shooting in more ways than just deciding on whether or not you're hitting the slide stop. I have improved my recoil management lots since reviewing my tapes and you'll probably find room for improvement too. Humble pie is delicious.

It happens all the time, esp with the .40's. Video taping won't show anything unless you have a high speed camera to capture the movement during recoil and review in slow motion. Try a magazine left handed and I bet the problem disappears. Once you know for sure that it is your technique, you can address that.

It's common with sub-compacts for people to accidentally hit the slide stop and lock the slide back upon recoil, especially with an extended slide stop but also with the standard version. When I first got my G27 I was accidentally holding the slide stop down so the slide would fail to lock back, I changed my grip and haven't had that problem since.

I had the same issue with my 27. Take a pair of pliers and pinch the slide release down a bit where it goes over the frame. Some of them are too loose and easy to hit.

A high, thumbs forward grip provides much better control of the gun and allows for faster, more accurate shooting. Adjusting your grip to compensate for a hardware deficiency makes no sense. Fix the gun, don't break your grip.

 

[Bren]

Never mind

 

[Bren]

I'll have to take you at your word the slide stop is in right. Work on your grip.

 

[sixgun2]

Haven't read all the responces, however if it hasn't been mentioned try shooting left handed.
Good luck

I can't ignore that most posts like this include "after detail stripping... "

Double (or triple) check that everything is installed correctly, even if you know what you're doing, you can still make a mistake. Brain farts happen. If this didn't happen before your detail strip, I find it hard to believe that that would have nothing to do with it.

I agree with Bren, that it sounds like the tip of the spring is resting on top of the locking block pin.

Make sure it looks like this:

I agree.. based on my description your comment makes sense but long ago I learned this lesson the hard way and even at the range, I broke down the gun and the checked that the spring is "under" the pin... Like I said.. I learned this lesson the hard way years ago.

In this case however it was installed correctly and I even popped out the pin and put it back just in case I was losing my mind..

No doubt however, I was using a "new for me" grip with my thumbs very high... Ill go out to the range and give it a go with a reasonable grip.. Hope thats all it was...

Huh...any chance that you put the locking block pin in after the slide lock? That would cause your problem, as that pin provides the spring tension for the slide lock. With no spring tension it will just flop around randomly.

Yes. Happened to me with a G27 I've had and shot for well over 10 years. Changed the springs and was checking it out, just putting lead downrange, with ball and defense rounds. Locked back frequently half way through a mag with multiple mags. Wasn't until after I left the range I figured out it was just shifting in my hand half way through the string and I was hitting the slide stop release. Same grip I've always used with it. Dope slapped myself....went back a few days later and fired it again more "conventionally"....problem never recurred.

The heavier recoil of the G27 does make it more likely your thumb will jump up. However, the same heavier recoil makes if more likely a slide release lever with a weak spring will do it on its own. I have had both happen.

Im guessing this will be the same situation as me... or hoping at least! :supergrin:
