| I have these on my G-18 mags, and they have been 100%, but they are basically play mags. What's the opinion on using these for duty or CCW? I'm considering adding 6 rounds to what I carry on my belt and possibly a couple of rounds to my reload with CCW. Are Glock extensions the only ones worth considering or are there others that are GTG? |

I loaded up a G27 mag with a factory +2 extension one day. About an hour into carrying, the rounds blew out the bottom of the mag body. The extension pushed straight off the bottom with the pressure of a full mag inserted into the gun. This mag was brand new and purchased new with the mag extension installed by the factory. So, no, I didn't fuck up the install.
I've used G26 +2 mags without issue. But the G27 +2 mags were a no-go for me. After realizing how the extended baseplate could be pushed directly off the mag body with enough pressure, I've stopped using them. |

I'd be a little leery about the mag extensions that add capacity, even the Glock extensions.
At one time, Glock did not recommend them for LE duty use because they were too easy to damage. I don't know if this is their current stance or not, just a little tidbit learned in an armorer's course probably 10 years ago. As to why they don't recommend them, I have firsthand knowledge of that. We used to have a guy who worked at my PD that carried a G17 with the Glock extender. He was walking in the Station one day and smacked the extender off of a door frame, not very hard, either. Extender came off, ammo everywhere. Apparently, according to what we were told in this armorer's class, this was a fairly common problem with the extenders in LE service, which was why they didn't recommend them anymore. Now, you don't say if you are using them for LE or for CC. If you want to use them, go for it, as long as they prove to be reliable for you. But, please bear in mind that they are more fragile than magazines without them and that the possibility exists for them to break or otherwise come off, leaving you with only the round in the chamber. I'd recommend against them, based on my experiences, but you are free to make your own choices. Bub75 |
| If you are going to get extensions use ones that are popular for USPSA. While it is a game, it is a game that doesn't accept equipment failures. Check out Dawson, Arrando(sp?), or Taylor Freelance. I use Taylor Freelance, and I don't see anyways they are coming off. That said do not drop a fully loaded one onto steel from chest height. I watched one that was installed on a Korean mag tube, and the bottom of the mag broke off still attached to the extension. |

Thanks for the replies. I'll put extensions on a couple of mags and torture them a bit. Will see how they hold up. Not going to put those on any working mags yet. That's the right way to go. I'm not trying to convince you not to use the +2 extensions, just to try them out a bit first.

| Every magazine I buy, gets a Pierce +2 extender put on it. I've never had any issues what so ever with them. I only keep one magazine without, that's for deep concealment days, other than that, they've all been flawless. Many days in the back yard practicing speed and tactical reloads, dumping them in the grass and dirt, they run flawless at the range the next range trip. |

So far I've had no problems with the Pearce PG-39 extensions on my Glock .40 and 9mm mags. However, they are supposed to add 2 rounds in .40 and 3 in 9mm to the capacity of the mags. While I can fit that many in, it feels like I'm compressing the spring too far to do it and I worry that the base will fly off. It takes too much force, IMHO, to get the last round in so I only load +1 in .40 and +2 in 9mm.
I'd bet the the failures folks have experienced are a result of over stressing the mag to get the advertised capacity. My advice, at least for the PG-39, is to download by one and be happy with the extra round or two that you get. It will make it much easier to load a full mag on a closed slide, too. ETA: with the PG-39s on my 19 mags, my fingers get pinched between the mag extension and the frame of my 19. It is easier to use Glock 17 mags for extra capacity. |

Arrendondos, no doubt.
The +5s and +2s are tough. I drop mine hundreds of times per week. The feed lips or follower on the mag fails before the extensions do. By the time you buy an OEM kit and increased power spring, you are close to the price of an arrendondo +2 kit. The arredondos are also very easy removed- way easier than the factory floorplate, for cleaning. |
