SPF - Glock G21, 45ACP, Gen3. I installed extended controls for slide stop release, slide lock and mag release. I also installed a set of Truglo TFO (tritium fiber optic) sights, yellow rear and green front. Unknown round count but I have put about 300-400 rounds through it. It's in great shape. Comes with Glock plastic case, manual, 2 13 round mags, gun lock, cleaning brush and mag loader. $600.00. Not interested in trades at this time.
