What would you guys suggest for one of those 30 or 33 round extended mags for a Glock 30s (. 45acp)? I be seen the crappy aftermarket ones at gun shoes but I would never trust those as they look like plastic and tin metal.
I wouldn’t - Glock never made 30+ round magazines for .45. The only reason they made them for 9mm is because they made a fully automatic 9mm machine pistol version of the Glock 17 called the Glock 18 for European police and military sales and a 30+ round magazine was required for that.
All the 30+ rounders for .45 are aftermarket and I’ve never seen one that didn’t have problems or wasn’t crap in some way.
I use Glock 33 round mags for both my Glock 19 and my Kel-Tec Sub 2000. Glock is the best no question about that.
That being said, I also have some made by SGM Tactical. They are used in a Glock meltdown video on YouTube by Iraqveteran8888 and never failed.
Glock is best, but I have both.
Magpul recently released a 27 round and 21 round Glock mag too. I have the 21 round and am waiting on the 27 round to become available.
For the G21, the Korean made ones are good, the Scherer ones are junk, in my experience, per my earlier post.
