Plenty of duty pistols are measured against the Gen4 Glock 17. It has a 4.49-inch barrel, a 17-round magazine, and a textured grip with interchangeable backstraps. This used example has night sights installed.

Night sights make a difference when the lights are low. The glowing dots help you line up the pistol without a flashlight, and they are easy to learn. Check the sights when you receive the gun and compare their brightness. Tritium vials fade slowly over the years, so older sets may be dimmer than new ones.

The Gen4 uses a dual recoil spring, which smooths the cycling and cuts recoil. It also has a reversible magazine catch, so left-handed shooters can set the gun up for their hand. Together these changes make it a friendly pistol for new shooters and a reliable one for experienced hands.

When it arrives, check the slide, frame, and barrel for wear. Seat the magazine and test the lockback. Fire a few magazines to confirm the pistol feeds your chosen ammunition. The price reflects a used gun, but the design is proven and parts are easy to find. It is sold as described, in used condition. The pistol ships to your local FFL dealer, where the background check is completed.
