Glock wrapped the barrel with a highly durable and reliable polymer frame to provide a long service life. 

This lightweight polymer framed pistol weighs just 29 ounces without magazine and the Safe Action trigger maintains a consistent and reliable trigger pull for added confidence.

This Glock pistol checks a lot of boxes for home defense or personal defense users with a strong steel barrel, durable polymer frame, compact design and simple operation. These features make this Glock a powerful, smooth drawing pistol that easily adapts to any users hands by changing the backstraps. If you are looking for semi-auto, striker fire pistol with the power to handle any situation with confidence than the Glock 21 is a great option.
