The old V-spring Colts are beautifully made and a delight to fire. I have no real basis for it, but I have always felt that they were more accurate than comparable S&W's. But as practical guns today, they have drawbacks. They do tend to require service more often than S&W's or Rugers, and parts are becoming very hard to obtain, even from Colt. Plus gunsmiths who want to (and can) work on them are thin on the ground, and they are easy guns to damage if the gunsmith doesn't know what he is doing.
So mostly my Colts stay in the safe when the Smiths go to the range.
