I think all guns are pretty, honestly. I think the ONLY gun that is so ugly that I am embarrassed for it is the high-point. especially te older .45's.....geez. is there nothing they can do for the aesthetics and keep the same mechanical workings that they use?
I don't think Glock's are "pretty", but I think they have a cool minimalist utilitarian look. I think Chiappa Rhino's look freakin awesome for reason. Actually I can't think of a single revolver that isn't appealing to look at, maybe the LCr places last, but it's still neat. okay, okay, nevermind, I forgot about the Taurus 605 poly that comes in white with bright green grips.....that pretty much tops the ugly list.
prettiest semi sa/da autos? BHP's, 1911's(of course), CZ anything, witnesses, baby eagle(Jericho?), Sig 938 SAS(does anyone have one by the way, never seen one in person or on the forum, beautiful gun), ummm..Lugers of course, although not sa/da
single action....man, they are all so pretty. I would have to say probably the good ole' 3 screw stainless Blackhawk .45 or maybe freedom arms model 83 casull.
da/sa revolvers....I hate to keep saying Ruger, for one I don't even own one or have even shot one, but they make the prettiest darn things I have ever seen. I think my ultimate dream revolver is probably the "Alaskan", but I wouldn't throw the GP100 outta bed either. I think the big Taurus Trackers look pretty sweet too. I know smith probably makes the nest revolvers in the world, but they re just plain to me, never really turned me on.
prettiest striker fired? I dunno, I guess it would have to be the Sphinx, or some of the modular sig offerings. although they are all nice, they have a hard time standing out between each other.
I unfortunately dont own any pretty handguns yet, I do have a SS lever-action that is pretty sexy, and I find my super tacticooled mosin nagnt pretty neat too, although I know I am probably in the minority on that one. but I think "almost" every gun is "pretty" in it's own rite, even a zev glock race gun
