HIGH-TECH-Arrived-Gun Damage

[Easterner9504]

Received G:HT today Pistol damage has some interesting twists.

.45 ACP 2D pi+ Unchanged from basic GURPS
.40 S&W 2D+2 pi+ Basic was 2D so now more powerful than .45 ACP
.45 GAP 2D pi+ Equal to .45 ACP despite smaller case
.357 SIG 3D-1 pi A 9mm equal to .45 ACP (17 vs 18 max damage)
10mm 3D-1 pi+ Pretty powerful, odd it never caught on
.50AE 4D pi+

How exactly does .40 & .357 come out so good in GURPS
