I'm going to buy a new gun anyway...
I've already picked it out, but fixing up a worn but reliable pistol is something I never really thought about. I have to give the credit to my wife. She's the one who convinced me to do the work.
She also OK'd my next pistol purchase, which will be over $1K. I must have married well...
The only trouble with fixing up this gun is that now I'm looking at my guns going "This one deserves fixing up, this one doesn't, this one..."
It's even more fun than buying a new gun because I do all the work except the bluing or plating. It gives me a good excuse to spend hours at the workbench fiddling with guns.
