    I already had the Gen 1 for my Glock 20/21 (I utilize the system for my Glock 20). I love the increased capability with having an actual magazine retention/release button, compared to just relying on friction to work and gravity NOT to work with every shot fired from my system. I also love the rigidity in the brace on this system, versus the Gen one which is just rubber, even though I did love how it would just eat the recoil. Absolutely LOVE IT!!!!
