I am a fan of just about all guns, but...
Strangely, I just can't get into Hi-Powers. But, I dig 1911s.
Can't get into Ruger autos, any cowboy-ish revolver, or pretty much any revolver with a long barrel (meaning anything not a snubby).
Not into the target guns with all the fancy grips and counter weights, etc., or fancy race guns for competition.
Just about anything else will float my boat. I like wide diversity in my collection, and I have nothing against the guns listed above, they just don't interest me as much as others.
