chances are its ready to rock as it is. i'd say take it to the range, put three or four hundred (thats alot) of rounds through it. if it fires them all with no hiccups, id say your all set. as for checking for wear, look at the magazine lips for excessive wear, and check out the feed ramp. if both look good, and it shoots well, then you have yourself a damn good gun.

3rd gen? Well, I guess it depends on the obvious wear when you get it. Some haven't seen 500 rounds. I guess some depends on the price you paid also. Of course we know it won't be in pristine condition, but you'll have to take it to the range, break it down, and figure out what shape it's in. Personally, I wouldn't buy anything in anticipation of your Glock. I'll bet it's okay with everything as is. Clean and lube it like you would anything else. Then send us your range report of the G17 you got for a good price off Gunbroker! Good luck with it, right now spend on ammo to test it.

You already have night sights and mags covered. If the gun works, which it almost surely will, you're good to go.

Cool, Thanks for the replies.

Not to be nosey but what was your final bid? Just curious.

$395, I hope I didn't get took.

Just bought a 2nd gen. G17 (1989). Shipped it off to Smyrna for a parts upgrade. Wow! They turned my A- Glock into an A+. They replaced the "weekend" rear sights with the new adjustables. Here's the run down on the new parts: firing pin assembly, firing pin safety, extractor, trigger assembly, mag. catch, slide stop, slide lock, spring, recoil spring, locking block and new case too. Hellz yeah. The only thing out of pocket for me was the $53 for overnight shipping.
