I recently bought a new Colt Government series 80 that has the firing pin block. A lot of folks remove it and put a shim where the lever goes in the frame. I like the idea because the trigger has to be pulled to fire the gun. From what I have read, the drop test is one of the reasons for the aluminum trigger. less inertia when dropped. I do carry cocked and locked often and think the firing pin block is a good idea for me. I wouldn't carry my 1908 vest pocket chambered though.
I hope your new gun works out alright for you. I bet it does!
peace,
gordon
