The Glock 19 Gen4 is designed for function first. This design philosophy means that the gun parts fit together more loosely than most, making it not as accurate as competition-level pistols.

The Glock 19 was released as a “compact” variant in 1988 and has evolved through several generations, terminating most recently with the Gen5 introduced in 2017.
