If you like your gun and it shoots well for you,consider contacting Jim Olivant at Highland Stock Fitters (931-648-8289). For extremely reasonable rates, with fast turn-around, he does exceptionally good work installing adjustable combs and butt plates to make your gun a perfect fit. He has worked on several of my guns and I am completely satisfied with each job.
Stock work is one of those things that is almost always done better by an experienced professional than by even a talented amateur.
Disclaimer: My only connection with Jim is as a happy customer and fellow cigar and clays enthusiast.
