Besides selling glock parts we do full glock gunsmithing/customization. Here is a slide we did for a customer that we are sending off today. He had the slide cut for a low mounted doctor sight, and front cocking serations added. The serrations match the rear serations and do not run through the glock logo. I think it looks pretty damn nice (with the exceptions of my fingerprints on the slide which are not visable except by the camera, my photo kung fu is limited). The customer is so excited. I guess he's got plans to add a threaded barrel and a suppressor to this heater.
