Bought a G35. This magazine has the baseplate that fits flush on my hand. 13 is my max in that gun. Don’t get the G41 mag that’s made by Kriss and Magtek for 1/2 the price. Just because the G41 mag is listed for your G21 and the fit is sloppy doesn’t mean you can screw your OEM parts. The Kriss/Mag G41 doesn’t seat in my hand with ammo loaded, so you get funky feeding.
