Go over to the Gunfighters forum or CFDA,california fast draw association.I have to get some myself,i got me some fast darw holsters awhile back from Greg Custodio,he can tell ya anything you need to know too,thay have a fast draw every month in Los Banos.You can also get Quick Cals DVD on how to make your own.I always get to many things goin at once and need to prioritise a little more,i just like to collect too much..Greg is very knowledgeable about the shooting sports,he even has a write up on how to shoot and take care of those vintage BB revolvers from Hahn and Crosman,i have a few of them.He told me you just put a dab of oil on the tip of the co2 that goes in them to lube the seals and when you put the co2 in just hand tighten,pull the hammer back and pop a couple shots to seal it good for shootin,it's the action of the hammer and such that seats them down,to many people like myself at first would try to crank the co2 down as hard as they could,then i learned the right way..You can find what you need at CFDA...
