The Gen 4 Glock 21 is now a reality.  The Glock 21 is one of the more discussed models from the company:  on the one hand, it gives the shooter 13+1 rounds of the powerful .45 ACP to handle whatever threat may present itself.  On the other hand, the gun is noticeably thicker than other Glock models, creating problems for many shooters with small to medium sized hands.
With the Gen 4 treatment to the model 21, Glock will hopefully satisfy all of their fans who like the cartridge developed some hundred years ago. Â One of the major changes to the Gen 4 pistols is the modular back strap system that allows the owner to custom fit the size of each gun to his or her hand. Â While the “Does size matter?” argument will never go away, Glock has certainly made a credible effort to make the 21 comfortably useable by most shooters.
