If I own the gun for years, $3k (which is the starting rate listed on JJ's site for a boxlock restocking) isn't a whole lot of money - especially if it fits me properly, an achievement that no other guns I own hold at the moment. I may get some wood extensions for the comb and butt to start with, it'll make it into a bit of a Franken-gun but it would provide enough material to allow the fitting to be done on that gun itself. Larson's faux-grain looks pretty good in photos, if I decide to hold off on restocking for an extended period of time I can have it painted up and blended properly.
I'm wary of self diagnosing because I've almost certainly picked up some bad mounting habits as a result of shooting nothing short guns, I'd really prefer someone who knows what they're doing to help fix issues like that and get me sorted out.
