Back to the pistol-cartridge carbines thing Updated

Ran across this the other day, and it includes this table comparing each cartridge from pistol and from carbine:
Terminal Performance Comparison

Load	Gun	MV (fps)	EXP (inches)	RW (grains)	PEN (inches)
9 mm 124-grain Speer Gold Dot	Pistol	1,182 (50)	.71	124	13.25
9 mm 124-grain Speer Gold Dot	Carbine	1,352	.45	107	17.50
9 mm Federal 115-grain JHP	Pistol	1,117 (59)	.57	114	14.50
9 mm Federal 115-grain JHP	Carbine	1,318	.50	70	16.00

.45 ACP 185-grain Speer Gold Dot	Carbine	1,279	.68	160	14.75
.45 ACP 165-grain Cor-Bon +P JHP	Pistol	1,264 (89)	.78	68	10.25
.45 ACP 165-grain Cor-Bon +P JHP	Carbine	1,633	NA	NA	5.75
.45 ACP 145-grain Glaser Silver Safety Slug	Pistol	1,362 (41)	NA	NA	7.00
.45 ACP 145-grain Glaser Silver Safety Slug	Carbine	1,617	NA	NA	8.00

Most of them the carbine gets ~200fps advantage except the Cor-Bon +P, which gained 369fps.

Update: Skidmark reminded me of this site: Ballistics by the Inch.  They take a bunch of different cartridges and loads and start with a 19" barrel, then cut it down an inch at a time and check velocity along the way.
They also take standard off-the-shelf firearms and check velocity through them.  Well worth looking at.
