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...

Even cheaper at BudsGunShop
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.
