Bob's right, sometimes projects are just for fun with no practical reason to do it. Now, when I had my 360J done I was an LEO looking for a lightweight 9mm snubby for a BUG but no one made them, all the ones available were around 22oz. When mine was done I had the 13oz 9mm snub that I wanted. That was all business.
Right now I'm having one done that's just for fun because I had the base gun and got a good deal on the conversion parts. I sent Mark Hartshorne a beater S&W M28 .357mag, along with a titanium .41mag cylinder I got from Numrich's for $85 and a nice 4" M58 barrel I found on ebay for $80. He'll be sending me back a 3" RB .41mag M28, think 3" M13 on steroids! When it's done I'll have $600-$700 or so into the conversion, not including the gun itself, but, what the hell, I'll be the only kid on my block that has one. It should make and outstanding car and hiking gun.
