Let me give you an example.
A few years back I was poking around in a pawn shop here in Kodiak and some old guy was trying to sell a gun, but the pawnbroker wanted no part of it. I followed the guy outside and learned he was a trapper (or had been for many years). Now, he was down on his luck and selling his old trap line pistol. I checked it out - the bluing was 90% gone and the exterior pitted and generally awful. Yet, the action was as tight as when it was first made, and the bore was pristine. I asked him what he wanted for it and he said $100. I handed him $100 and walked away.
The gun is a Colt Peacemaker .22, from the 60's or 70's. The exterior was so bad I didn't worry about collector value. I got out my fine steel wool and took it down to the white, then sprayed on some teflon coating (I think it was Bear-Kote), baked it in my oven and now had a really fine old Colt pistol with a new and very durable finish. I still use that Colt all the time. It's fun to shoot and accurate enough to hit a sitting bunny in the eye at any reasonable range. It's not the prettiest gun around, but it's still better than anything you'd buy new for three times that amount.
Total investment - maybe $125 and a few hours time. With reasonable care, my grandkids will shoot this gun, and their grandkids too, perhaps. Had the pawnbroker bought it, I'd have probably paid $175 for it and it would still be a bargain.
No new $200 pistol is going to have that kind of durability or accuracy with all the plastic and metal stampings and pot metal. Get thee to the pawn shop!
