The GLOCK(R) 19 Gen5 Semi-Auto Pistol - 9mm is probably the staple compact carry firearm that all are measured by. Sized between the sub-compact 26 and the full-size 17, the 19 is a happy medium. It's the choice firearm of many law enforcement agencies worldwide and a very popular concealed carry firearm. The G19 comes with the same popular upgrades of all Generation 5 GLOCK pistols like the GLOCK Marksman Barrel and overall elimination of leaf springs, which have since been replaced by new coil spring designs for increased longevity and reliability. The slide release is ambidextrous and the magazine catch is reversible. The slide has factory serrations on the front and back.
