Title: Anyone use Pierce Magazine Extenders on Glock 40 Magazines?
Post by: 1911 10mm on July 04 2018 08:01:51 PM MDT
Anyone have experience with Pierce magazine extension on Glock 40 Magazine? This are supposed to add two rounds going from 15 to 17 rounds per mag. Just curious about reliability.

I use them on my Glock 20 mags.  My standard load out for EDC is my Glock 20 with a 15 round magazine, carried in a Vedder Lighttuck at about 1:30.  I carry 1 or 2 spare magazines with me, both Glock 15 round mags with the +2 extensions.  I have had no issues in reliability with them and would expect the same in a Glock 40.

I only use the Pearce extensions on my G-29 mags but have a few 15 rounders with the AGrip adapters sleeves.
I don't add the extensions on my G-20 because I carry concealed it at times...

I run them on my G29.

12+1 rounds of 10mm in a relatively compact package.

Thanks for the information. I have ordered three from Pierce for my magazines. Brand new Glock 40 and my vortex venom will be here today! If only my practice ammo would arrive!

I no longer have my 1911 RIA in 10mm as it was just a POS lemon. I sent it packing. Wonder if I can change my username?

That's unfortunate, my RIA Ultra FS HC 10 runs great

With Glock magazines, I've shied away from anything that isn't the current design 2-piece factory extension.  I worked with someone in my old department that put the Pierce on his magazines.  One time on a call, he bumped his gun on the vehicle pillar when getting back into the driver's seat.  His rounds went everywhere (it was actually kind of funny).

The original Glock + extensions sometimes had this issue.  The newer 2-piece design (Parts 7151 (indicated with a +) & 7165 (insert) - both required) won't move.  Direct from Glock, they are $5.00 & $2.00 respectively.  It will add two rounds for 9mm & .357 Sig, and 1 for .40 S&W & .45 GAP (although you usually can get 2-rounds in with the .40 once the spring settles).  Also, make sure you use the 11-coil (33601) spring.  The .40 mags should already have it, but just verify it isn't the 10-coil used in 9mm and the original .40 magazines.

I'm guessing most people are fine with the Pierce, I just wouldn't use them for duty use where they could be bumped hard.

I received them in and don't know how they would come off by a bump as they are a real pain to get off and back on a magazine! I just can't see them coming off by a bump.
