The best trigger ever made is the old steel short tang 31 and next is the long tang. Only problem is they are very complex and most gunsmiths will not attempt to repair or convert to release. I had Allems do it at the grand in 1985 but doubt that guy who actually did the work is still around.All the oldtimer gunsmiths are gone
Most gunsmiths would not do them as they were dangerous they would fire with out the gun being closed and difficult to unset as release for the forearm is forward on the right side. I am not sure but there was not a disengagement in the design or some thing missing that is in a model 12 or 870 there were some made but I was always fearful of using one.
