Glock G45 Gen5 FS 9mm 4.02″ PA455S203

The GLOCK 45 Gen5 FS is a crossover 9mm pistol that pairs a compact slide with a full-size frame to give a shooter a full grip and improved control while retaining compact slide handling. It features the Glock Marksman Barrel with polygonal rifling and an nDLC-finished steel slide with front serrations and fixed 3-dot sights. The pistol is built on a polymer frame with an accessory rail and includes ambidextrous slide stop levers for greater versatility.

For a red-dot optic under $1,000 that complements the G45’s slide profile and sight picture, consider a Holosun 507C or a similarly sized micro red dot designed for duty or competition use.
