Glock 10mm ammo question

[STI]

I'm picking up a Glock 20sf this Tuesday and I'm planning to only shoot the hottest loads I can find. I have heard good things about Underwood ammo so I will be trying out some of their different loads until I start reloading. My question is, in its stock form, can the Glock 20 take the consistent punishment of full house loads, or should I change the recoil spring, barrel?

Unless you plan on saving the brass to reload, I wouldn't change a thing. Stock form will handle it just fine.

I do plan on reloading, but I will put at least a few hundred factory rounds through it first.

Probably need a recoil spring for 100% reliability.

I've ran hundreds of Underwood, Buffalo Bore, and my own reloads (which are hotter than both brands) through my G20 with the stock spring. Haven't had an issue.....

You'll be fine.....

looking for the "hottest loads possible" I assume you are looking for hunting type loads were penetration is key. For that a heavy hard cast will out perform hollow points etc.

The 200gr Underwood is about 1250fps but the Double Tap 200gr is 1300fps 750lbs

On my Glocks I had to switch the barrels to more supported Wolf barrel, as the "Glock smiles" we're dangerously big! This doesn't happen with all Glocks but with both of mine it did. I also added a stiffer recoil wolf spring and stronger magazine spring. The wolf barrel needed the stronger springs to feed as reliably as the stock barrel.

This^^^^

I run hot loads without issues with the stock 17 pound spring. I also have a longslide that does have a 22 pound spring in it but that heavy slide needs that extra spring tension to cycle. When you're shooting hunting loads pick a recipe (handloaded) that you want and be prepared to swap springs.

This guy on YouTube has dozens of 10MM videos and ammo tests. Here is one to get started.

Memo: DoubleTap isn't as fast as they claim. Just saying.

This morning I reloaded some 175 Grain Silvertip with 9.2 grains of Longshot into new cases. Should run about 1250 FPS which is perfect for my G20SF.
With the stock spring.

I just bought a 20SF not to long ago and it has quickly become my favorite gun. I've shot Load X 200gr XTP, Underwood 200gr XTP Underwood 180gr GD, and LAX 180gr FMJ. I'm definitely sticking with Underwood. Great ammo at a great price.

I've used the stock spring as well as a 20lb Glockmeister spring and had zero problems with either.

Ok thanks guys, I feel better now.

Only thing I've heard of is the stock barrel shouldn't shoot just plain lead ammo without frequent cleaning due to the rifling Glock uses. I suspect the issue is overblown but don't know.

all i shoot is underwood 180gr and 200gr threw my 20sf. probably have 500ish rounds threw it and no problems so far, good ammo.

The gun will handle any round that is safe to shoot without worry.

If you want to reload, look at getting an aftermarket barrel.

I left my Glock 20 stock and it worked fine until I tried shooting reloads with coated bullets. I installed an aftermarket barrel from Storm Lake with conventional rifling and it works fine with the coated bullet reloads. If you use jacketed bullets, you won't run into this problem. With coated bullets I can see some keyholing of the rounds and greatly diminished accuracy with the stock barrel. Other than that, the Glock 20 is reliable and there's no need to replace anything.

I love my Glock 20. I've shot 1000's of rounds through it and it is bone stock.

I put a G20SF on layaway at ammo bros, can't wait till I try some of these different ammos.
