Slim is the right word for the Glock 36. It is a compact single-stack .45 ACP with a 6-round magazine, a 3.78 inch barrel and a weight of about 1.25 pounds. The finish is black.

This one is a law enforcement trade-in. The seller thinks it was a backup sidearm or a plainclothes officer's pistol, and says it shows signs of daily use but remains in very good shape overall. It has tritium night sights and one 6-round magazine.

The slim grip makes the G36 easier to carry than a double-stack .45, and the .45 ACP round gives you a heavy bullet in a small package. The trade-off is capacity and recoil. Six rounds is not many, and the small frame will move more than a full-size pistol. Spend some range time with it.

The seller notes that most officers fire their pistols mostly for qualification, so the wear is usually from holsters and handling rather than rounds fired. That is a common pattern. It is sold used and as described. It ships to your FFL dealer, and the background check is completed there.
