Amish_Bill, I understand what you're saying. My $600 1911 is now a $750 1911 because I added night sights. Also spent some $$$ to make sure it's 100% reliable.
Maybe it's just a matter of affordability. If I could come close to even affording to buy an Ed Brown or Les Baer pistol, it would be my pride and joy. I couldn't imagine subjecting it to holster wear. Would it be more reliable or accurate than my current carry gun? Dunno. I'm not as accurate a shooter as my current carry gun is.
For someone who can buy a Les Baer or Ed Brown pistol without a second thought, I suppose the notion of holster wear may not be an issue.
It's similar to my situation with bikes. I've got a Harley that I've had for years and, even though it has well over 100,000 miles on it, I baby it. When I see riders going out on the first warm day of the year with brand-new $20,000+ bikes when there's still 2" of salt in piles on the streets, I cringe. But, for those riders, rust may not matter because they can afford to buy a new bike in a year or two.
