I have always preferred to have a hammer on and auto pistol. It is not a make or break thing but yes, hammers are my thing.
John Browning put hammers both internal and external on some of his designs but he actually preferred strikers and thought just the one safety was enough to carry a gun cocked and chambered, tho again he put grip safeties on some.
I do like a decocker especially the kind on the Sigs. I can live with a P-38 decocker but it takes longer to use.
I suspect Browning liked to have the slide totally enclosed which is why he preferred a hammerless.
He put a grip safety on the 1911 because the military at the time demanded it.
The first ones he summited did not have a grip safety.
He corrected the mistakes of the 1911 when he designed the browning Hi-power.
