Like Remington Dave, I had a Smith 657 three-inch that I miss every day. I had traded a scoped Redhawk in 41 Mag for it, then tore into it and perfected my trigger smoothing skills on it. It had the sweetest trigger I've ever stroked, and that takes in a lot of triggers over 40 years. It was too big for an off-duty gun so I sold it to raise funds for the then-new 40 caliber, which I amazingly still have and shoot often.
The other one was a rifle, a Rem 788 in 22-250 that I found used with an old Weaver 3X9 scope on it. The rifle hated factory loads, but good handloads would shoot under a half-inch on breezy days, a quarter-inch on still days. A sergeant I liked talked me out of it, and I gave him a sweet deal on it. I bet he hasn't used up the ammo that came with it, he just liked the way I had shaped the stock and refinished it. Now if you'll excuse me, I have to go slam my head into a wall for being such an idiot.
