The big difference I see is when lowering the hammer on a loaded chamber. The opportunity for an AD due to a thumb slip certainly exists. I know that for a fact...
That's what the crossbolt safety is for.
Yep, have always been partial to the presafety Marlins, but 11 year old daughter showed me that the safety has it place. Kids especially can let that hammer slip when lowering. Luckily were practicing an unloaded rifle.
