New Glcok 20 owner here and I was recently at a gun show here in California. I noticed a bulk ammo booth that did not recomend Armscor 10mm ammo for Glocks. Any body have any experience with this ammo for Glock 20's :confused:

Welcome to the forum Stormbringer!! I have used the 9mm from Armscor and have been through almost an entire 1000 case without one issue.

Thanks for the welcome, I was waiting to respond as I did manage to put 100 rds through my Clock 20 sf and my second shot with the Armscor 10mm 180 gr. , the casing stuck upon ejection. I managed to clear the gun then fired the remaining 98 rds without a hitch. I saved the casing to show how why it jammed. It appears the ejector stripped the brass casing so it did not get a firm grip on it. I'll post a pic soon to show. For the most part the rounds went through cleanly after that.

I shoot my G20 some. It is hard on brass and the ejector is tough on the rims. Not sure why? The 10mm is a beast. I was considering it for my CCW weapon in G29 frame, until I started testing some JHP ammo. I have not found a JHP bullet that will stand up to the 10mm except the Hornady XTP and they penetrate like mad. I'm talking 30 inches of water and then thru the bottom of a steel barrel and buried in the dirt so deep I can't find them. 10mm is sort of like the 41/44 mags. good dangerous critter gun, but not at all suited for CCW.

Underwood Ammo makes some excellent 10mm offerings. TNoutdoors9 on YouTube has quite a few ballistic tests to show of it.

In those tests the bullets fragment due to the increases velocity, and I think that it what he was talking about.

The 180 grain did pretty well. I'll agree I wasn't a fan of the lighter weights
