A guy has one local for 550. From the pics it looks to be in good shape. 3 mags (i have not been able to learn if the mags are gen1 also)

He wants 550. Fair price?

If it has the Tupperware case and (2) NON-drop free mags, yes. I would take it.

Gen 1 is getting difficult to find. The NON-drop free mags are even harder to get
now-a-days. Glock traded owners of NON-drop free mags for drop free mags
when they first appeared. That took a lot of them off the streets. there are fewer
NON-drop free mags than gen 1 G17's.

I doubt the mags are original.

There are (16) iterations to Glock mags as well. If memory serves, the first two iterations are
generation 1.

Newer mags. Gun dates to the mid 80s.

If the gun is in nice shape, I would take it for a collection.

What are your plans for it? I collect Glock and do not yet
have a gen 1 G17. I mainly focus on G19's for collecting.
I'm at (13) G19's at present. All different in some way except
(2) gen 2's. Those are alike.

If your collecting the 17's, yes, take it in good condition at the price.
Offer 500 and see where it goes.

500 is highest I would go.  Unless you collect the Gen2 is a better older Glock and can be had for less.  Honestly I have no want myself for a Gen1 and would not pay more than 350-400 as they do not a huge appeal to me.

I'm a shooter not a collector so I wouldn't pay that much. 

I bought my first Gen-1 in 1988 for $350.00. I bought my second one in 2013 for $425.00. Your location may also affect the price.

Not my video, but a good video for Glock mag identification.

It's more or less a $550 price tag to simply say you have one.

As noted in other threads and Glock themselves, the polymer DOES get a bit brittle over time, so I wouldn't consider it a shooter.

If you have cash to burn and a desire to say "yea, I got one", then go for it.

Why does anyone want a Gen 1? Brand new Gen 4's can be had for almost the exact same price. IMO the early Glock pistols are inferior in every way. These are economy pistols to begin with, not collector items.

I currently own a Gen 3 G23 and G19 and Gen 4 G35 and G21. I paid $600 for G35 and the rest were under $550 new.

Thanks. I have that vid saved. Don't know why I was thinking (16) iterations of Glock mags.

I stand corrected. It's (17) iterations, not (16). That vid is very accurate as far as I know.

x2....I totally agree here.

i have a G19 from very early 1989 (barrel is date coded Jan 1989 and serial numbers all match).

The polymer frame on that gun IS indeed, harder, than a new gen 4 G19. However, it does shoot
fine without issue. But, the issue is this:

When you go paying more money for a used Glock for a collection (has makers mark), and the
frame ends up cracking; then, what do you have? A old plastic framed gun that's either:

A) unsafe to fire because of cracked frame -or-
B) send the frame to Glock and they replace it with a new gen 3 frame.
You then have a older MIS-matched serial numbered gun along with
loosing up to half it's value, depending on what you paid for it.

So, rationally and financially, the old Glock goes to collection -or-
I make it a shooter, not worrying whether the frame cracks.

And, if that's the case, I should NOT pay more than 400-450 for the used Glock.
But, I wouldn't want a gen 1 as my only shooter.

The "only" Glock I have that I would not want to shoot any longer is my old G19.
As I stated, it shoots fine, but, I had to pay near 500 to get my hands on it. I cannot replace
it's frame with a like frame; that is serial number and makers mark. I carry G26. So, it sits in the safe along with
it's (9) sibling G19's. The other (3) have guard duty.....

I do keep three (19's) hidden around the house. Call me paranoid.....or prepared????

So are baseball cards; just some cardboard LOL.....Peeps can collect most anything.

It's the best one I've seen. Told me that there was a LOT about Glock mags I didn't know.

I sold a G1 for $600 with original box, one original mag, and some holster wear. Had it on a FB gun group just right before the shutdown and was getting offers up to $700. So if you really want one it's probably not bad, I wouldn't buy it, but I'm more after shooters than collectors.

x2. Never knew how much effort Glock put into mag design and yet keeps them universal with all gens.

That's one of the reasons I'm hesitant to switch to Magpul or ETS mags.

I've got some of the ETS mags for my 17. They work in my 17 and 19.

This thread is timely, I've been thinking about a Gen 1 17.

During our local gun show last weekend, I saw a Gen 1 17 for 400.  Nearly bought it if I hadn't been there for a Sig 1911.
