Speer Gold Dot G2 Carbine 9mm

[Ziggidy]

I recently received notification about this ammo and never heard about Carbine 9mm ammo; specifically

Speer Gold Dot G2 Carbine 9mm Luger Ammo 135 Grain Hollow Point​

What is the difference and what are the benefits? Can you use this in a handgun, any dangers?

Cost is $1.12 per round!!!

I would assume, specifically designed for "longer barrels", hence carbine, versus the normal for pistol barrels

I understand that. I was wondering what makes a 9mm a carbine 9mm versus standard 9mm.

 

[Ziggidy]

It’s a real question. I’ll be sure to make a batch of popcorn for your entertainment. Movie style or extra butter?

 

[Ziggidy]

They make 9mm for carbine so not make .38 spec for carbine? .357?

Carbine length barrels increase velocity. JHP bullets designed to perform well at normal handgun velocities may overexpand and underpenetrate at increased carbine velocities. I’m guessing that this carbine specific ammo addresses that.

Makes little difference for FMJ ammo, obviously. Just a little more penetration at increased velocity.

Thanks! Appreciate it.

They also may use a slower burning powder to reach higher velocities out of a longer barrel. I did some experiments years ago with, umm... un-named powder in 40 S&W in a Kel Tek SUB2000 and achieved better than 10mm handgun ballistics. Probably not the best idea in a straight blowback firearm but it was interesting….

Do they list any kind of velocity? If do, do they specify a barrel length?

 

[Born2vette]

Interestingly they do not specify barrel length with their muzzle velocity. For comparison, 9mm gold dot 124gr has a listed MV of 1150 out of a 4” barrel and 9mm + p Gold dot LE 1220 in 4”

I read somewhere you should not use this carbine ammo in a handgun. No specific reasons given.

Wonder if this ammo would beef up the potency of the many micro-nines on the market?

A load optimized for performance in a long barrel would probably not perform as well in a short barrel.

I understand that. I was wondering what makes a 9mm a carbine 9mm versus standard 9mm.

I would expect slower burning powders that would take advantage of the longer barrel's longer dwell time to deliver higher velocities. They would likely perform poorly out of 3.5 or 4 inches
