i don't know. i guess I've never sold a gun, nor ever plan to. maybe thats where the thinking comes from. i traded one once, for another gun, and have regrets.......
i guess what I'm trying to say is that to me its a hobby. gun building for most here is a hobby. No one wants to spend $1000 on parts and end up with a $200 gun, but you can spend $200 on a $200 gun, buy a $150 lock, still end up with a $200 gun, have had some fun doing the conversion, probably learned a thing or two, and end up with whatever ignition shooter you were looking for. if you have to sell it then part it out, you'll get your money back mostly.
the venerable CVA is generally the guns most can afford to mess around with, if it gets ruined, nothing is really lost other than a couple hundred bucks, and you'll still be able to part that out. most of us here have spent more on stupider things. if the gun gets messed up, and they are fairly easily replaced. if it works and lots good, great.
My .45 is one of those 70`s ones but the lock is pretty good. it could have been replaced sometime before i got it. will i ever convert it? i don't know, it crosses my mind, but if i decide to i`ll do it.
