Can a Glock 17 fire the first generation of Speer G2 147gr rounds?

[Tony617]

I am still using my first generation of Speer G2 147gr 9mm as range ammo since it does not do well in 4" barrels. My new Glock 17 has a 4.49" barrel. Can I use it for self defense now? No big deal if no one knows the answer since is makes good range ammo.

What about it doesn't do well in a 4" barrel?

Do your own test. Make some ballistic gel or do a Paul Harrell meat target.
In any case, it's likely to be ok for defense use. I've yet to meet a person that could tell you whether a bullet is expanded properly when it's lodged in their shoulder. Or brain.

"Gold Dot G2 ammo is simply unsuitable for use in a compact or subcompact pistol"

Good info! Thanks for posting.

Speer released an updated G2 version 147gr but have not tried it. I am using Federal 147gr HST rounds for self defense.

I run Speer Gold Dot as my carry ammo. Shooting a Glock G45.

I still have some older non-G2 Speer Gold Dots in 124gr and 147gr. I was talking about the first generation G2 147gr made in 2014 did not expand properly from a 3" or 4" barrel.

I think I will use the G2 9mm as range ammo only. I don't want to cast ballistic gel or anything like that to test like 8 boxes of G2 ammo.

This is my answer as well. If I have any apprehensions about ammunition performance I just don't use it in my carry guns. Best to just put it to use during practice and carry something with proven performance.

Hmm. Interesting. I know the "old" gen Gold Dots tend to do just fine. I wonder what went wrong?
