This guide will show you the standard and optional magazine capacity of every Glock pistol currently on the market. This list does not include pistols that are labeled "law enforcement only" or training and instruction Glocks.

Each Glock handgun comes with a standard size magazine but may be compatible with larger magazine sizes to increase the number of rounds the gun can fire before needing to be reloaded.
