I understand that. I was wondering what makes a 9mm a carbine 9mm versus standard 9mm.I would assume, specifically designed for "longer barrels", hence carbine, versus the normal for pistol barrels
It’s a real question. I’ll be sure to make a batch of popcorn for your entertainment. Movie style or extra butter?
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.I understand that. I was wondering what makes a 9mm a carbine 9mm versus standard 9mm.
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….Carbine length barrels increase velocity.

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

A load optimized for performance in a long barrel would probably not perform as well in a short barrel.Wonder if this ammo would beef up the potency of the many micro-nines on the market?

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