I've tried them all-Sig Trailside, Smith and Wesson(don't remember the model), Ruger, and Buckmark. The Buckmark is the one I've kept through it all. I just picked up a used one like pictured above with the flat sided barrel. Great guns.
Dad has a 5.5 Field target as well. He also had a Varmint with an aimpoint on it but sold it!
