This is a SAI g17 slide that will fit any WE and TM Glock 17. It also comes with any outer barrel I have listed at the moment, at no extra charge. And it will come with standard glock sights, with no sight screws. It’s worn a bit, and it is full metal, but the top is cracked a bit, otherwise it works perfectly, and does the job well. Price is not firm so hit me up with offers for sales or trades.
