Funny you should not only mention the idea of using one gun for everything field target, including rifle and pistol, but also think of me Scott. I'm flattered. Perhaps great minds do think alike!
While I was still able to shoot field target locally I started working toward that very goal. Felt a 1720T the proper platform, so bought a used one and drilled out the TP to soup it up (actually too much, to 13.2 FP). Only got to shoot it in one RIFLE match (never in a pistol match), and took third out of 8 Hunters. At that time the trigger was breaking at over two pounds, and it was obvious that cost me a lot of points. Monkeyed the trigger down to about six ounces, but never got to use the 1720T in FT again due to the ban.
From that one experience I learned I'd prefer more weight on the gun for pistol and rifle FT work. For me that means pretty (and heavy) wood forend, grips and (for RFT) a Corcoran stock. Unwilling to invest $600 in a new stock, I recently placed a WTB ad on the yellow classifieds with nary a single response.
Kind of a moot point for me now; since I don't get to shoot FT much these days so have moved into "real gun" competitions. I do admire your "Abby Normal" approaches to field target Bud, not to mention your outstanding shooting skills.
