Owners of the Great Lakes Firearms GL19 Striker highlight the optic-ready cut as the standout feature, with the RMR footprint considered a practical advantage for those who run red dots. The Galaxy Platinum finish draws consistent attention on the range and is described as durable in everyday handling.

The ambidextrous controls are appreciated by left-handed shooters, and the 4-inch barrel gives a familiar full-size feel. Some owners find the factory trigger adequate but note that an aftermarket drop-in improves the pull noticeably.
