    Add some power to large frame Glocks

    I bought several of these, for my 10mm and .45 (more on that in a second). Got 20 rounds reliably in the 10mm with 400 rounds down flawless. It’s not listed to work with g21/41. And it doesn’t. Unless you are willing to modify the follower for the 45 acp which I did. Got me +3 45 acp. I’ve put 300 rounds through that too without an issue whatsoever. 16+1 in a 45acp is awesome

    Glock 20 mag extension

    I could only get 18 in the mag. So that’s +3. Awesome product though. Doesn’t come with floor plate. I may grind the tab off factory mag plate. May take a little messing around with to get it right. All in all great product.
