@Sxynerd; have you had any issues with the glock mag extension? I am most worried about dropping a partial or near fully loaded mag and having the baseplate hit just right and send the bullets and spring shooting out the bottom. I don't know why they don't include that extra security of the raised nipple on the mag insert. Many times in a competition, I may need to drop a mag after 1 or 2 rounds fired and I fear the above scenario.
Also, I just got my arredondo mag extensions. Extremely happy with their method of installation. And for an extra quarter inch of mag length, you get +6 9mm instead of the +2 from the factory mag extension.
Anyway, I fall on the glock love side. Of course, I love me some Walther PPQ/P99 and also have much love for the Sigs. Hell, I love most guns. Even that butt ugly Chiappa Rhino!
I'm leaning towards a G21 because I want a .45 but don't necessarily need something that big. I'm going to do some research and hold a few before I make a choice. There are definitely too many to choose from.
Check out the G21SF or any Gen4 G21. The SF has a slimmer/shorter frame for smaller hands, and the gen4 glocks have multiple backstrap sizes. After owning multiple Gen3 glocks, I've completely fallen in love with the upgrades of the gen4.
