Like no other pistol, Glock pistols permit almost unrestricted compatibility of the magazines within a caliber. Standard magazines, for instance, can also be used for backup weapons. Compact and subcompact Glock pistol model magazines can be loaded with a convincing number of rounds - i.e. Glock 26: up to 33 rounds. The innovative polymer frame of the Glock pistol does not require grip shells. As a result, it has considerably more space for the magazine body and enables double-row staggered cartridge configuration. For this reason, Glock pistols are superior in firepower to conventional pistol models of the same size. Glock magazines have a stiff metal tube encased in the proven Glock high tech polymer. This resists deformation - even when dropped from great height or exposed to extreme environment conditions. For Gen 4 and Gen 5.

I ordered and recieved five extra 13 round magazines for my Bud's purchased Glock 21 .45 ACP. They work well and I am very pleased with the transaction.

Paired this with the X grip for my Glock 30s and I love the way it feels! Functions well and looks clean.

Brand new 13 round Factory Glock mag for my Glock 41. Replaced a few of these since they notches where it snaps into the catch have visibility worn a bit and I want to avoid any future trouble. Perfect price and service from Buds as usual!
