Thread: Glock 21SF Mag Catch Just Fell Out!

I've had my Glock 21SF for about 6 months now. Have shot about 50 rounds through it. I was pushing the mag release to release a full mag and it fell out but the button was pretty stiff. Couple minutes later when I was messing with the Glock, the mag catch just fell out. I did a google search and it seems like this is pretty common with the ambi model 21SF. Anyone else have this problem. I thought these things were suppose to be indestructible. Calling Glock today to see what they have to say.

Well I just got off the phone with customer service at Glock. Very very helpful. Turns out that they are seeing this problem a lot and have discontinued the ambi SF frame. They are sending me a prepaid fedex label and will be replacing mine with their standard SF frame at no charge.

Oh man, i had the same issue awhile back. They didnt send me the prepaid label. I have to ship it to them for 64 bucks. :-(

what about the serial # on the new frame? It wont match?

Hmmmm....Gonna hafta check mine out. My ambi-mag release is also very stiff.

I had my doubts about the design when I first checked them out. I'm glad I held off.

I usually hold off on buying the first run of anything. Glocks are good guns, but they've had their fair share of teething problems with new models. That being said, I'd like to see them stick with the ambi release, to appeal to more buyers.

I'm on my third Glock 21SF.

First one had that big stoopid Picatinny rail hanging off the front end (and ambi magazine release). Didn't realize it before I bought the pistol, but there are hardly any holsters for a G21 size gun and that schnauzer looking rail.

Second G21SF had the much more svelte Glock rail, but also had the ambi magazine release. Put a few rounds through that pistol, fit in my holsters and everything, hated that damn magazine release. There has never been any need for it and it has never worked correctly. My biggest peeve with it was that trying to eject a full magazine just about took a 2lb hammer. That whole ambi-magazine release they cam up with is/was a cluster frack (gotta remember where I’m posting here). Glad to hear that they are discontinuing it and going back to their proven simple design. Never did get to get a magazine release to fall out.

To get the third G21SF with the Glock rail and old normal non-ambi magazine release I really had to go out of my way. Called all over this state and the Vancouver area looking for one and finally had to get one off Gunbroker. Came in from a New Mexico FFL as a Kalifornia gun with a white label and two 10-round magazines. Sucks, but I got the Glock I wanted, just had to jump through a few hoops to get there. Not too hot, not too cold, just right. Great gun and I love it.

Now, I won a certificate in the ABC House match earlier this year for a Bar-Sto barrel. Ordered it for the G21SF and waited (they're not kidding either when they say the wait will be 14 to 16 weeks for a barrel). Got the barrel here a few weeks ago and although it is a semi-drop-in (80% drop in, 20% need to be fitted) mine is in the 20%, so off it wet to Bar-Sto to get fitted. Gun will still need sights (Henie Straight 8s) and I should have the big G21SF dilemma concluded.

So the pin fell out and it didn't explode.. you did get a dud.

Had mine for 2 years, so far no problems. Mag release works fine so far. Sorry to hear so many are having issues with there 21sf.

That's right: My 21SF had a problem so the ambi frame was switched out at the factory for a non-ambi one, which has a new and unrelated number. They have a record of it, and it makes no difference to me anyway.

As a lefty, I run into ergo issues from time to time with firearms, but a mag release isn't usually the problem. I just use my index finger. I use the slide release with the left index finger as well.

Sounds like they're going to take care of you, Glock customer service seems to be one of the best in the business.

I've got a non-ambi 21SF and absolutely love it.

Little update on my 21. I called Glock again before I sent the gun in and asked them if they could switch the frame out for one with a standard rail rather than the picatinny. They let me know that they've also discontinued the picatinny rail and my new frame will have the standard rail. Awesome!

You should have bought an xd, metal mag release that's ambi.

Heaven forbid, you didnt need your 21sf to protect yourself, when this happened, because you couldn't hold your gun one handed, without the mag falling out of it
