My most expensive handgun off the shelf was this S&W PC1911 ($1650). Most accurate .45 ACP I've ever shot. Had to put in a new sear and hammer spring to get the trigger up to 3 1/2 lbs for bullseye. It shoots way better than my ability. A 25 yard group fired bullseye style.
My most expensive handgun after custom work is my Ruger Bisley .475 Linebaugh built by Linebaugh Custom Guns ($3000!) Closest thing I've ever seen to absolute perfection.
