Buying a police trade-in with a weapon light already on it saves you a separate purchase. This Glock 21 SF comes with a Streamlight TLR-1 and Glock night sights, plus three magazines and the box.

The G21 is a big-framed .45 ACP with a 13 round magazine and a 4.61 inch barrel. The SF in the name stands for short frame, which slims the grip so that smaller and medium hands can reach the trigger and controls with less strain. It is a good pistol for anyone who wants .45 power without the blocky feel of the original.

The seller grades the pistol as Good and lists the bore as 7.5 out of 10, with the condition also at 7.5 out of 10. There are scratches and dings, and the seller says it is in 100% working order. It is used and sold as described, so study every photo for the exact marks.

A pistol with some holster wear and a light mounted has probably done its share of work. Put fresh batteries in the light if you plan to use it. It ships to a licensed dealer near you, where you complete the background check.
