Well I wanted to put some info on these out there since there is little about them. I received two Mecgar plus 2 extension from G&R. These are for the full size guns but will work for the compacts also in 9mm, 40s&w, .357 sig. I am completely happy with the end product. I added two rounds of 40 S&W while keeping the same size as the factory finger extension. If I had a 9mm I feel that the extension would give you 3 extra rounds. The mag extensions fit perfect, drop free and lock the slide back 100% of the time so far with factory springs. They match the grip of the gun very close but just a tad bit off. Range test yesterday included 146 rounds. They were each 100% with Federal 96 rounds of 180 grain walmart ammo, and 50 speer gold dot HP 180 grain. Hope this helps anyone interested in these extensions. Thank you Grant!
