    I squeezed 16 in my mag yesterday on accident. Has anyone tested to see if 16 rounds in a g20 mag will be reliable

    Well, if it's just for fun at the range, you could go for it, but the truth is those mags are designed for 15 rounds. Getting the extra one in is a clue that maybe the spring is not up to specifications and should be replaced. If it's for self defense, definitely put a new spring in there.

    I did put a plus 2 ext on it could that have weakend the spring. the 16th round was super hard to get in and almost squeezed out but like i said didnt keep track of 1-15 i was just putting them in.

    the Arredondo floorplates will get you 5 more rounds...making a factory mag a 20-rounder. I use these in 45 as well, for 17 rounds in the spare mag. they work well, stay put and are reliable. not cheap, buts its likeley a one time purchase.

    Tne Arredondo kits simply rule!

    I have them on my GLock 21 (17+1) and 35 (20+1) mags, and have a few kits in reserve for use with my GLock 20 mags as well...

    (3 mags so equipped ensures you will never run out of ammo, even with 3 Texas counter rotating stars and a bad day of front sight focus!) :)

    Dang what do you guys think your going to need 20 rounds of 10mm for? the end of the world?

    Sucks we can only get 10 round mags here in CA but 20 just seems like over kill and more weight to lug around.
  9. If mags held 20 rounds each, some people would want 25. I went through 20 years of police work and my .357 magnum never held more than six. But times change. Fifteen rounds is plenty. My G20's heavy enough and I can imagine how heavy a 21 must be.

    Interesting. I got a couple of the +2 kits from the Glockmeister and they are awful tight. I usually end up just putting 1 more in there or just putting in 15. When I need some rebuild kits, I might try some of these +5 kits.
