The Buckmark is a large and heavy gun.
I like the discontinued 422/622/2206/2213/2214 series of handguns, though the black finish is not durable.
The Beretta 70/71 pistols are perfect for your needs but are pricey.
Ruger standard and Colt Woodsman pistols are also large and heavy.
The K22 is a good shooter but heavy, I would prefer to carry a 10/64...and usually do.
