i have a 3 or 4 1389's Allan inc the green pistol grips to go with them -i need to put a 2289g together at some point
i think i have a few new green stock and backpacker fore arms and some black ones
the high pressure valves i'm not a fan off as they wear the gun out faster than the low pressure set up
power wise i can get as much power from the lp higher volume valve as the hp low volume one ,and the hp valve runs out of steam about 12fpe so in the US the low pressure high volume setup is used more but at the cost of more pumps
