Well, my G20 didn't blow up

[Lennyjoe]

I took the new G20 out tonight to shoot it for the first time.

First 100 rounds were 11.0gr of Blue Dot under 180gr Speer TMJ and WLP primers. Also had in a new 20lb recoil spring. There was a little bit of a bulge in the brass but nothing critical. The brass was chucked about 15 feet away from me. Accuracy was ok but that's cause I haven't shot a Glock in quite a while.

Second 100 rounds were with a 22lb recoil spring. Brass went about 8 feet away. Same looking brass. Slight bulge but nothing spectacular.

Also shot 15 rounds of 175gr Silvertip and put them all in the head at 15yds. Group was around 3". All with the 22lb recoil spring.

Last group was my heavy loads of 180gr Hornady XTP's over 9.6gr of 800X and CCI mag primers. The brass wasn't bulged as much as the Blue Dot but still had a bit of a hump there. The 800X load didn't recoil as bad as the Blue Dot. I found that odd.

For now I'll shoot it with the factory barrel but next week (payday) I plan on either getting a Storm Lake, KKM or a Jarvis barrel for it. Still doing some research on the barrels and availability but for now I have found this;

Storm Lake is $129 + $6 shipping
KKM from Glockmeister is $164 + tax and shipping
Jarvis barrels are $190
Bar-Sto barrels are $200 + several weeks wait.

Ok, so why did you think it would blow up? I shoot my 20 with double tap all the time and have never had a problem. Whats the prob? The G20 is the best 10mm auto out there bar none.

Get a Federal Arms G20 barrel.

SS too and a tighter chamber with more case supprt.

Don't see very many case buldges anymore - UNLESS I push it and go MCNETT on my loads

Of all of my glocks, you can run a 357 sig, 40 cal, and 10mm barrel in there.

As a reloader, you can actually light load 40 cal to near 9mm recoil so you can have it hot or soft

Guess you didnt see the sarcasm in my thread name huh.

I knew it wouldn't but with all the threads lately on the G20 I figured I'd start this off with a bit of sarcasm.

Get a Federal Arms G20 barrel

I've searched around on the web for them but have come up empty. Who's supplying them? I checked on TopGlock as well but didnt see any.

Get a chronograph and a 6" barrel, lots of fun for the reloader. I've got a 6" KKM and it works great.

 

[boldkharma]

Sorry, I'm so sensitive to that kinda talk........

 

[Lennyjoe]

Does getting a 6" barrel include a slide as well or is it gonna look goofy having 1.5" hanging out the front?

Well, my G20 didn't blow up

It must be defective.

Not at all.

Competition guns look that way too.

No big whoop.

Lets see what you say after you've accumulated some brass than's been thru the gun 4 or 5 times, or more

I've .45ACP brass with over 30 loadings on them I don't worry about them blowing out. They all split at the mouth eventually when entering the sizing die, if I don't lose them first. Reload 10mm for a gun with poor case head support, no thanks, not my cup of tea, especially in a plastic gun.

Wally, what does the plastic have to do with anything? You don't really think that the frame has anything to do with case support, power of loads one might use, etc., do you?

If I did a lot of 10mm reloading for Glocks, I'd probably get a KKM barrel. I'd keep the plastic frame.

Hey Lenny,
You may want to look at EFK Firedragon Barrels.
I had a .40Smith conversion barrel for my old G29 and it worked great!!
They do require some minor smithing, though!!
TopGlock has 'em for $140.

Check out the gun zone's collection of KaBoom! photos. It truly has no effect as to if the case lets go or not, but it does affect the consequences!

http://www.thegunzone.com/index2.html You'll have to use the search function on some variation of kaboom.

I think it very wise to get a barrel with better case head support if you reload for Glock .40S&W or 10mm.

[michiganfan]

Mine hasnt blown up yet but I know I take my life in my hands every time.

 

[Lennyjoe]

I think I'll stick with a stock length barrel. If I want to go to a 6" then I'll see if I can find a longer slide for the unit.

denfoote, thanks for the heads up on the barrels.

As for the kaboom issues. Factory ammo isn't an issue but us reloaders that like to try different loads should look into a fully supported chamber. Thats why I'm looking at getting an aftermarket barrel.

 

[Lennyjoe]

If anyone cares, I just ordered a Storm Lake barrel for the Glockster. Stock length.

Expecting a slightly used G20 357 sig Federal Arms stock length barrel myself - while we're talking barrels in the mail

 

[Lennyjoe]

Sweet. I was thinking of getting a couple of conversion barrels (.357 Sig and .40) but would rather buy the pistols instead since I'm paying LEO cost on them.

Okay but I can still my Glocks for $399.99

Wally: Next, I guess you'll tell me you're getting your legal advice from Ayoob!!! Get a better source. You could put a Glock slide on a wooden frame, and it'd work just fine. Let's try a little brain exercise for a moment: What part do you think the frame plays in containing chamber pressure? Think really hard, now; this isn't rocket science.

All series or just the mini's?

I can get the G17,19,22,23,26,27,31,32,33 for $399

The G20,21,29,30,36 are $474

A better source? Pictures speak for themselves.

What part does the frame play in containing chamber pressure? None. Once the case head ruptures, it is no longer chamber pressure you are containing (you already *failed* to contain the chamber pressure; that is the point), its "inside the frame" pressure you are containing... at that point, the frame material becomes very important. A little brain excersizing and rocket science indeed...

I'm with Lennyjoe; were I reloading 10mm Glock brass, it wouldn't be brass that came out of a factory Glock barrel. Hopefully I can post pics of my very own G20 soon.

Most of the series except for the 34 and 35.

I depends when I am looking. When you know several FFLs, it really helps on your pricing. Being in the gun of the month club helps too.

 

[Lennyjoe]

Good point.

The only other Glock models I would be interested in are the 29 and possibly a mini in .357 Sig.
