My only beef with Springfield (and several others) is aesthetic. Ever notice how the front strap of the slide doesn't wrap back to the leading edge of the grip? Anytime I build up a Springfield (and most others except S&W and Colt), the first thing I do is get out a 12" double cut file and hog that thing down and shape the front strap to where it's supposed to be. Literally my only complaint with Springfield; and that's a pretty nit-picky complaint.
I know you do a good job, but you do charge a little more for that don't you?
Depends...short answer is; I don't work for free.
If I'm building a full custom pistol and it has my name on it, it's included. I will quote the full pistol as a package; I don't parse it out by line item because there are oodles of little things like that I want done before I put my name on a gun.
If I'm doing item by item custom work, and the gun doesn't have my name on the side, then I will offer that as a line item cost. It's $50.00.
