Glock 20 upgrades

[strokesdmb]

Are there any upgrades that you can do to a glock 20 in regards to performance? I'm new to glocks so any input/advice would be appreciated. Thank you

Since you're new to Glocks, I would suggest you run the G20 in stock form, right out of the box for several hundred rounds. It is an incredible handgun.

You might consider getting some particular sights that fit your eyes and work for you.

I do change out the slide release to an extended model because that's a personal preference.

Have fun.!

(Consider reloading if you're going to shoot a lot)

If you don't like the trigger pull, look into the ghost 3.5# trigger connector

The glock 20 is fine the way it is. But shoot it a few times first. But if i was going to up upgrade it, I would first upgrade to a match barrel. Then i would change out the stock sights to something like night sights or sights that i like. Lastly ,it would be a 3.5 trigger connector and maybe the 25cent trigger job if i wanted to smooth out the trigger.

But instead of buying upgrades I would buy more ammo that is always a good idea. Can never have enough ammo.

My first thing is sights. I hate the stock ones. But go shoot it a bit and see how you feel about them first...

What's a match grade barrel gonna do for the guy?

Better and constant grouping compared to a stock barrel?? Not saying glocks barrels are bad but the camber is a little looser for more reliable. where a match grade barrel will have a little tighter tolerance which helps with precision. A drop in match barrel is less constant than a match barrel that needs a gunsmith to be fitted.
Some people would say, it is not necessary for a glock, which is true. But there are many reason some people to want to upgrade their glock for whatever reason they believe. It not for me to judge it is their freedom to choose.
So the OP asked for what upgrade he could do to his glock20 i listed a few. But there are people that say match barrels for glocks are useless and some will beg for differ. But i rather have normal rifling than the glock hexagonal rifling for target shooting. But if it was for defense only i would most likly keep the stock barrel.

But if there is any knowledge that I am missing please feel free to fill me in.

check out this video of hickok45 playing with a glock 20. and he swaps out his barrel just to show a comparison.

As a former Glock 20 owner, the only thing I feel that's a necessity to change out is the recoil spring. I suggest a steel captured guide rod with 24 pound flat wound recoil spring from ISMI. As it sits, the stock recoil spring is too weak for stout loads. Fantastic gun, though. Miss mine.

After you run the weapon for a while, you will decide what upgrades you need.

On the subject of an aftermarket barrel; these are usually Lonewolf, KKM or Stormlake. Others exist but in practical reality, these are good enough. The only three reasons to run a stainless KKM barrel (for example) is you reload 10MM and want to shoot lead instead of plated or jacketed bullets. Glock barrels will run lead BUT it has to be a Brinnell Hardness of 18 or more. Hardcast lead to that standard costs about as much as plated Berrys or Raineer boolets...

The second reason is if you reload and shoot thru a stock barrel, as gts408 pointed out, the chambers on GLOCK barrels are about .008 thousanths larger diameter than an aftermarket Lonewolf or KKM (for example). Glocks are built for war and built to feed any-old-crap you pick up off the ground. This is a good thing really. But the case expands and has to be resized FULL LENGTH before reloading. This puts 'some' stress on the case. When shooting thru my KKM barrel (for example) the case cannot expand as much and is much easier to resize full length. I can easily tell the difference when I come back from the range with a bucket of empty cases; which ones I fired thru the stock glock barrel and which cases I fired thru the KKM. Much easier to resize on the KKM rounds. Not really a big deal but something to know.

A third reason is case support. This is only an issue if you're reloading 10MM up at the top of the envelope. Say 1300 FPS and 180 grain doing 700 foot pounds. High pressure in 10MM is easy to obtain; so is over-pressure and the stock Glock barrel (not so much the newer G20s) has a relief (ramp) for feeding the round at the 6 O'Clock position. This small area is unsupported and hot rounds can give you a piece of brass that gets a BULGE called a GLOCK SMILE. Way over pressure can rupture that back part of the case. Aftermarket barrels like the KKM have much more support so Hot Hunting Loads are safer.

The stock Glock barrel will run any hot commericial ammo you can buy, without problems. It's the custom handloads that push over the top that can cause trouble sometimes. I recommend www.underwoodammo.com

Kevin, the owner of Underwood really does a good job and his ammo is powerful and at reasonable costs.

Remember the stock GLOCK barrel is more reliable in the feeding department. So if you're traveling down thru town at night after the big earthquake, have the weapon in stock form.

My G20 has a stainless pin set (like a chrome clutch cable..haha) a set of TruGlo Tritium sights (for my bad eyes) an extended slide release and a 4.5 pound disconnector. (not the Ghost. Get the Glock factory one).

She runs 100% with my 175 Grain Winchester SilverTip Reloads and my pre-ban magazines with my Orange Floor Plates. (Orange floor plates tell me at a glance that these are rebuilt and have new wolff +10% springs and new followers; ready for action). Just my way of keeping track of my magazines. hahah.

Lately I've been reloading some Nosler 135 Grain hollow points and WOW....what a hoot to shoot. A loud CRACK and ZIP at 1530 FPS.....

Damn, I love it so.





The mag pouches (SHTF pouch) carry Five 15 round magazines and are available at Glockstore.com (when they catch up and can answer the phone).

A stock Glock can probably group 4-5" at 25 yards in a ransom rest, I am doubtful many here can shoot better than that offhand. Hickok 45 swaps out the barrel so he can shoot his lead reloads, not because of any accuracy gain.

i was talking about just the gun, gun vs gun. But if you want to talk about a normal person shooting offhand with a stock barrel vs. match barrel it gonna be hard to be constant so that is a whole different story. what about a stock glock in a rest Vs. a glock with a match barrel in a rest. Not "A glock can 4-5" @ 25y in a ransom rest but off hand i doubt anyone can." How does that prove anything, that stock barrel is as good as a match barrel. The only thing you proved is since the gun can do 4-5" at 25y, and offhand i can't do anything better. So why upgrade to a match barrel you ask? For you that is acceptable but for others it may not. Just because a gun works, doesn't mean a person can't upgrade their gun to make it easier for them to shoot. Isn't that why a lot of people upgrade their guns.

Your right, hickok45 switch barrels for his heavy cast bullets. Which could be another reason for the OP to get an aftermarket barrel. But watching the video i believe it made his shots more constant than using the stock barrel. But we can agree to disagree.

[Gts408]

An aftermarket barrel is not going to make the gun easier to shoot. People can dress up their guns however much they want, but understand what makes a gun accurate is the shooter.

The person shooting is the one in controlling the shots no doubt about that. I'm glad u know that. But hey if your gun is accurate enough that's good for you. But for people that buy triggers, match barrels and upgraded sights to make it more precise for them. Understand that. But hey it is only a glock.

If it were me, I'd put around 500 rounds thru her, then a $0.25 trigger job, trijicon HD sights, gtl21 or tlr2s, kydex holster and mag pouch, and put 5000 rounds thru her, then she's perfect. Oh, and maybe some grip tape (talon/skateboard tape/ maybe even stippling because she's a kicker!)
