I have a mint condition Belgian BHP with the black leatherette Browning gun rug. The "book" says that it was mfd. around 1973. It has the older adjustable sight. I like the way the gun shoots and handles, but I would like to have some reasonable modifications done to it. Things like a wider trigger and either have a beavertail installed or at least a different hammer to eliminate the bite that BHP's are famous for. My question is this. Will I be ruining a valuable firearms with some collector's value or will I be enhancing the value of this pistol by having this work done? If I did decide to have it done, who does the absolute best work? Thanks for any help.
