Glock mag question

I just bought a G 27 gen 4 and added the pearce +1 grip extension to the mags.

Over all I'm am very pleased with this gun. It's my first glock and it lived up to it's name today at the range. 100 + rounds and zero issues.

The extension is nice, however the +1 is a bit of an issue. I can get the 10th round in the mag, IF my thumbs aren't tired. :rolleyes: Seating the mag in the gun is an bigger issue. I really have to use two hands (one pushing from the top of the slide and one on the mag) to compress the mag spring enough to get the mag locked into place. Pretty awkward and SLOW.

Anyone else run into this issue?

I'm thinking loading 10 rounds in the mag isn't such a good idea if its under that much pressure.

So if I'm only going to load 9 in the mag should I get rid of the +1s and just get grip extensions that don't have the extra parts that the +1s have??:uhoh:

BTW I had no feeding issues with the last round. Its actually under quite a bit of tension.

Thanks for your input.

The mag springs will get easier with use. When I bought my FN 45 I was able to get the 1st 10 rounds in easily. The next 2 were all but impossible. I had to let the mags sit overnight before I could get in #13. I was able to get in #14 later in the day and #15 several hours later. I left the mags fully loaded for a few days until I could get to the range. It was a little stiff when reloading them the 2nd time, but was able to get all 15 in at once. After a few weeks they all load fairly easily now.

Doesn't really matter for the mag that's already in the gun. Just don't carry one of 'em for backup.

Let it sit loaded for a couple days and the spring should be broken in.

That's normal. I think new Glock magazines are hard to load to capacity as they were meant to be kept fully loaded. To break in, I usually load as many rounds as I can and leave it loaded. After a few weeks of being compressed, the magazine spring relaxes and I can load to capacity.

I also use Pearce mag extensions for my G27 and initially could only load 9 rounds. I kept 9 rounds loaded in the magazine and now I can load 10 rounds in the magazine+extension.

I went through the same thing with the 10 round mags that came with my 19C. After a few hundred rounds they are like butter. I could tell a difference in loading the mags letting them sit, unloading then reloading them a couple days later. I thought to buy a Pearce extension when I bought my gun, and the Arizona shooting occurred less than 2 weeks afterward so I had to take a back seat on getting some 15 or 17 round mags for a while, I wasn't about to pay $40 locally for a single factory mag.

I had a couple of the Pierce +2 extensions for my 26 when I first got it. I never was able to get the two extra rounds in the mag.

I have a number of Glocks and all the factory, as well as the Korean knock offs I have, all loaded easily to full capacity, even when new. The only time there was trouble was with the Pierce extensions (if I wanted the extra rounds).

Another issue I had with the extensions was, they pinched the hell out of my hands, both while shooting and especially while reloading, if I didnt watch my grip while doing so. I soon learned that the gun was easier to shoot with the factory mags without the extensions (its also smaller). It just takes a little getting used to, having your pinky wrapped under the mag.

Thanks for the info folks. I'll load them up with 10 and let them sit like that for a while.

All of the +whatever mag extensions I used on my glocks were actually +whatever-1 until the mags had been cycled several times.

Squeeze in all 10, try to get that last one, wash, rinse and repeat. :)

I intentionally download my Glock mags by one round.

So does Mr. Vickers. (http://vickerstactical.com/tactical-tips/magazines/)

It makes them much, much easier to insert with the slide forward. (Eg. Tactical reload in IDPA)

I use the pinky extensions, but no +1. They can be fully loaded with ease, but I usually only do that when practicing. It just takes time to break them in.

Dump the mag extensions, and if you really need to have a bigger grip frame, get a 19.

I tend to agree, except a 23 might be more appropriate seeing as how he has a .40 subcompact.

I don't think there is any harm in using extensions as they allow me to shoot my g27 as well as my other glocks.

With that said, you need to practice shooting without them, as that is probably how you are going to carry your gun. At this point, it's not comfortable to shoot without then, but my accuracy is improving. When I carry I keep a factory mag in my gun and a backup mag with the extension. In that format, the gun is much easier to conceal than a g23 or a g22.

Me either. I occasionally had issues when drawing my 26 and acquiring my grip. It was like my pinky got confused despite hundreds and hundreds of practice draw strokes and a couple thousand rounds. Toss in some trigger time on my 19 and it just compounded the problem. I finally just added a +2 extension. That added a fraction of an inch up front and virtually nil added at the rear. It didn't interfere with conceal-ability at all.

Whatever floats your boat or works for you...

Many double-column magazines can take extra effort to seat them against a closed slide, e.g., chambering a round and then inserting a full mag. This was quite noticeable with a Glock 30 I had, for example. When you need to reload, though, the slide will be locked back and you won't have this problem.

Have seen AR's do it. New tight is a great thing. Glock springs are tough new and having an extra finger groove does help when practicing. I have a 19 and 26 carry both but the 26 uses a flat plate for carry and extension for playing.

Guys if I wanted one of those glocks I would have bought one.

I like the size of the 27 a lot and the extension gives me a much better grip on the draw, and I have no issue carrying it with the extension. It hardly adds anything to the gun, maybe 3/4th of an inch to one side of the grip.

My only issue is seating the mag when I have 10 rounds loaded when the slide is forward. It seems from the posts that this is a very common issue with Glock mags and the spring will relax after some use.

Thanks for the input everyone. I've loaded up 10 rounds in each mag and I'll keep them like that for a bit. I also have one of those things that help load the mags. (It came with the gun, and so did a third mag BTW :)) I plan to use that to compress the mag spring of the fully loaded mag (over and over) while I'm watching TV to help the break in process.

Oh and BTW you can't do a tactical reload with a mag that is this hard to seat. (Which is why I have an issue with this) Yes if I was empty with the slide back not an issue at all, but that's not the only time I might decide to put a fully loaded mag in.
