There was quite a bit of engineering done apart from the trigger. IIRC it was 1983. I had a conversion done by Bowket on the FWB. It ended up with a .20" barrel from a Original 45, one of JBs barrel locks and full conversion which included modifying the piston anyway so a new latch rod,not silver steel
, was not a problem. It also got rid of the crappy plastic trigger
O ringed poly head, heavy piston, 5/32" port, one of his special 24 coil spring made by Wade, new guide and top hat. Smooth and low cocking effort. Standard stock
. Very low, contollable, soft recoil, so very quiet and accurate as hell.
Well, you asked
Wish I still had it
. He did quite a few to the same spec but 20ft/lbs with H&N Hollowpoints that were shipped over the pond.
All the spec. taken from my gun record log. I dont read it often. It makes me weep
