THIS IS A WORK IN PROGRESS!
Multiply the SR weapon's damage figure by 4/7 to get an approximate number of dice. Apply the stage 3 procedure from Adjusting Damage (GURPS High-Tech, page 166) to convert this to dice+modifiers. Or use this table:
SR4 | GURPS |
1 | 1d-2 |
2 | 1d |
3 | 2d-1 |
4 | 2d+1 |
5 | 3d |
6 | 3d+2 |
7 | 4d |
8 | 4d+2 |
9 | 5d |
10 | 6d-1 |
Convert armour penetration (AP) values thus:
SR4 | GURPS |
-5 | 0.2 |
-4 | 0.25 |
-3 | 0.3 |
-2 | 0.5 |
-1 | 0.75 |
0 | 1 |
+1 | 1.5 |
+2 | 2 |
SA weapons have a RoF of 3. BF weapons have a RoF of 10. FA weapons have a RoF of 30. Super machine guns (HVWs) have a RoF of 36.
Range, ST, Bulk and Rcl can be roughly assigned by weapon class, but should be subject to GM tweaking as seems appropriate.

Hold-out Pistol | pi- | 55/1,200 | 6 | -1 | 2 |

"+", "B" and "M" have their usual meanings.
Reduce Rcl by the weapon's RC value.
