What is the best custom handgun you've owned?  I have been fooling with handguns for over 20 years and have been fortunate to get my hands on several custom guns.  Some I had built for me and some I bought or traded for.  
4 stand out that I really wish I had kept.  Not all because they were great guns, 3 of them would now be worth bigggggg bucks.  They were -
1 ASP built on a 39-2 (original version, Theodore Paris)
2 ASP built on a 439 with buffalo horn grips(second version Armament Systems & Proecedures (Dr. Paarsons)
3 ASP .44 Spec built on Ruger Speed Six (I am still kicking mtself over that one)
4 PPK built by Ellicott Arms.
I've also owned several Novak built(actually Kurt Wickmann, who use to be the shop supervisor at Novak's) and Wilson guns.
What about you?
