I have one gun, and one gun only, that I consider a "admire on the sofa for its prettiness" gun, that I love to stroke and clean and ditz with. It's my Smith and Wesson Model 41. I've wanted one all my life, and at nearly 60 years old, could finally get one.
All my other guns are weapons. Regardless of what I've paid for them, I'm confident in their utility and function because I've beaten the living crap out of them and they always work. They are not weapons until they've had about 5,000 rounds through them, and they aren't weapons if they look like Detroit pimp guns with 'features' and crap accessories.
To each owner, his own preferences. If it gets carried, it shoots and I know it shoots.
But, I bought a Sig P220 Elite Stainless and the first thing to go was the pimp rosewood grips, replaced with rubber Hogues. Did it change the utility of the gun? Not at all. The rosewood grips were perfectly functional. Did I want to be seen with a gun with rosewood grips? Nope. This was a style choice, and we all make 'em. Had NOTHING to do with being functional--everything to do with looks and personal preference.
You carry what you trust your life with. 'Pretty' is perfectly fine...but 'not fired much' is not. Better know how she comes out of the holster 500 times in a row...it's kinda important.
