I have a G26 and large hands, so I found that Magpul makes "ranger plates" for glock mags. These things work very very well. Although they are not +2 rounds like some mag extentions but they feel very nice and comfortable. You can get a 3 pack for under $15 bucks and they fit most glock mags.........mine are for 9mm and 40/357. Just a thought y'all might want to look into.
