Just picked up a Gen 1 Glock 17 yesterday for a great price. When I first saw it I knew it would need a little TLC, but for the price I couldn't pass the opportunity up.
I don't know too much history on this particular gun except that it's an older model with serial number starting in AX###. The box has a label with something about 1987. I'm pretty sure the gun was carried by a police officer but don't know to what extent it was used. The gun had holster wear that was immediately apparent as well as ugly swirling scratches on both sides and top of the slide. The gun smelled old like it was sitting for years with gummed up/dried old lube in the deepest internal parts. The action was dry as a bone but the slide cycled surprisingly smooth. Trigger pull was also lighter and well worn-in compared to all my newer Glocks. It has the best feeling trigger of them all. There are a few scratches on the plastic grip. Upon field stripping it, the gun appeared as if it's never been cleaned but was overly lubed in all the wrong places quite some time ago. It was a mess.
So today I completely detail stripped the gun. The firing pin was totally caked with gummed up old junk. The extractor had build up behind it that wouldn't scrub off with a toothbrush and CLP, so I had to scrape it off with a small screwdriver. The trigger assembly didn't want to lift out because it was so gummed up in the frame. For being so neglected, the barrel is in excellent condition though. I don't have any doubt that the gun would still have functioned well in this condition, but it's unacceptable condition for me.
I used Kroil spray and a toothbrush and rag to soak all the parts and scrub all the old grime off. I thoroughly cleaned the slide, firing pin channel and extractor spring channel. I scrubbed around then blew it all out with compressed air. I didn't know how to rid the frame of the old oil smell so I threw it in the dishwasher along with the slide, mag tube and gummed up trigger assembly for a full cycle. They came out smelling fresh. There was still some residual junk inside frame and trigger assembly so I took care of that with Kroil, Q-tip's and a toothbrush. I cleaned every part spotless on the entire gun, lubed it properly and reassembled.
The gun functions very smooth now. I used a small piece of 2000 grit sandpaper and lightly sanded the slide. The scratches sanded out very quickly and now the slide has a nice uniform appearance. If I couldn't get the scratches out, I was going to send the gun to Glock to get the slide refinished but I actually like it how it is. The older used appearance of the gun gives it character and it's gonna be a shooter. The Gen 1 grip is the most comfortable I've ever felt; it's too bad they changed it to the newer texture and finger grooves in my opinion.
Upgrades I'll probably do to the gun are night sights, extended mag release and extended slide stop; other than that it's perfect for me. Good thing for having 17 round mags to bring the gun to it's full potential also. I plan on taking this thing out later today to try it out.
Here's a couple pics of it all cleaned up:
