Here is another Glock 21 SF that came out of police service with its gear intact. It has a Streamlight TLR-1 light and Ameriglo night sights, so it is set up for low light work as it stands.

The seller rates it Good and says it is in 100 percent working order, with some scratches and dings. It comes with three magazines. The pistol is chambered in .45 ACP, holds 13 rounds, and has a 4.61 inch barrel and a black finish. The SF frame is slimmer than the standard Glock .45 grip. Dry fire practice at home, with the pistol unloaded and ammunition in another room, builds a better trigger press.

Used pistols with a mounted light are handy for a nightstand, but they need a holster that fits the light if you plan to carry. Kydex holsters for the TLR-1 are common and not expensive.

The photos in the listing show the condition, and I would study them before buying. A few marks on the slide are a fair price to pay for a duty-grade light and sights. It is sold used and as described. It ships to your FFL dealer, and the background check is completed there.
