Glock G34 Gen5 MOS 9mm Luger Long-Slide, nDLC, Night Sights, Ranger Proof Trigger Shoe, 5.31 in GMB Barrel, 2x 17-Round Mags
This Glock G34 Gen5 MOS stands out as a full-size, long-slide 9mm with thoughtful upgrades and Gen5 features. It wears an nDLC-finished, solid (non-windowed) MOS slide over a 5.31 in Glock Marksman Barrel with polygonal rifling and an improved crown. Night sights and a Ranger Proof skeletonized trigger shoe set this example apart, while ambidextrous controls, a flared magwell, and front slide serrations round out a well-sorted configuration.

Upgrades include a Ranger Proof skeletonized trigger shoe. Trigger pull weight is typical for the G34 configuration and may vary.
Chambered in 9mm Luger with a 17+1 capacity, this pistol includes two 17-round OEM Glock magazines. It was manufactured in Austria and bears Austrian proof/inspection marks on the barrel, including an AT mark on the barrel hood.
