I have two favorite guns.
My overall fave is a stainless steel Gold Cup Custom Edition Colt Commander in 45ACP. I bought this in the mid 90's almost NIB with maybe 50 rounds through it tops. It came from the factory with a lowered & flared port, a beavertail, a beveled mag well, and a beautiful set of rosewood grips. I have since modified it to include a Videcki trigger, a full length two piece guide rod, an arched mainspring housing, a set of checkered wooden grips, and a set of tritium night sights that conform to the original Colt/Eliason style adjustable sights. It also has an action job with the trigger set to 4 lbs.
It's very accurate and I frequently use it as a carry piece.
Equally enjoyable to shoot is a Hammerli 208S in 22LR that I bought new in 2000. The gun is box stock except for an Ultradot sight. For bullseye, nothing beats a 208S.
