I pulled apart my vortex I got from my son that the trigger never been apart. crappy trigger, loaded with heavy lube of some kind inside. cleaned it up an removed the safety parts ,installed my best my highly polished worked over latch,trigger sear,saved the old parts for some other day reworking them. no safety for this setup as It,s not a light trigger but breaks like glass with no slack . no lube an it don,t seem to change with a consistant pull . they don,t wear out they wear in I couldn,t ask for more crisp trigger .
