Early Glock 20 question

[kdkdlsjiei93]

I have a Glock 20 that I bought in 1991 when they first came out. It's probably been fired about 100 times using range rounds right after I got it, no problems that I recall. I used to hunt and shoot rifles and shotguns a lot when I was young, but I've lived in the city in SoCal since I've had the glock and don't care much for shooting at indoor ranges.

Recently met someone who owns property in rural area of North San Diego county and he offered to let me come shoot at his range. I bought some modern higher powered 10mm ammo, double tap 180 gr, Winchester Silver Tips, Swamp Fox 180 gr. In the process of looking for ammo, I started reading some of the gun forums and saw people talking about using stronger recoil springs with hotter loads. I notice that the later generation glocks come with a captive spring/guide. My gun came with a non captive spring, I'm not sure what weight it is.

I was wondering if I should get a stronger spring/guide before shooting this ammo. Also wondering what other changes have been made to the glocks over the years. Are there any important modifications that I should consider making on my 1991 Glock 20?

Finally, does anyone know of any public outdoor ranges for handguns and/or shotguns in North San Diego county or thereabouts. Now that I've started reading and thinking about guns again, I have the urge to do some shooting and I don't want to impose on my acquaintance every time.

You have a rather rare Glock there. Would love to see a pic.
The stock weight is 17 pounds. You could get a newer Glock captured recoil spring, or go with an aftermarket guide rod and spring. 20 pounds should be plenty.
Wolff round wire springs fit any aftermarket guide rod. I would recommend a captured steel guide rod, the un-captured ones can be a PITA to get in the gun with a 20 or 22 pound spring.

An aftermarket spring is unnecessary. Call Glock and tell them your guide rod is uncaptured and they will send you a new captured one.

Thanks

Thanks for the replies. I would post a pic, but I'm one of the few people who don't own a digital camera. There aren't that many differences externally from the modern guns. The grip doesn't have finger impressions or the little dimple where your thumb rests. Also, the bottom part of the frame underneath the barrel looks more squared off and doesn't have any grooves for mounting accessories. I guess there are probably more changes in the internal parts.

As for the spring, I think I may try out an aftermarket Wolff spring. Even though it's probably not necessary, I'd kind of like to have a steel guide that's a little more permanent than the plastic one. And maybe I'll try Reaper's advice and see if Glock will see me a free one too.

That Wolf guide rod & spring is nice ( if your going to shoot a lot )

The factory spring is the way to go IMHO.

First, check your current recoil spring, and you can do this Armorers test yourself.

Unload the Glock and recheck again that it is clear.
Hold the Glock straight up at the ceiling and pull the slide back and 'gently release it'. If the recoil spring needs replaced the slide will not completely return to a fully closed position.

Recoil springs ( factory ones ) are recommended replaced at 3-5M rounds. So if you have not really shot this Glock, the spring still could be good to go. But I would still call and get a new one bro.

you're on the right track


if you're going to fire a lot of full power 10mm, i would suggest an uncaptured wolff heavier spring system. my friend's new G20 is already show damage to the polymer where the slide smacks the "U" shaped area near the takedown lever. he's been firing nuclear loads with the stock spring system. the heavier springs work fine with the low power loads too, so you don't have to keep changing them out.

i put the wolff uncaptured system in my G29. it really does reduce the muzzle flip a lot. i use the heavier weight spring with light 10mm loads too with no probs
