I have one in .45LC/.410 Shot Shell.
Trigger is a bit heavy. Recoil is mild. I is my BUG to my Colt LW Commander.
Never used one but we sell 2-3 just about every gun show (various O/U Bonds, not just the Texas Defender). They have a very loyal following. Never heard anyone complain but I sure have heard their owners rave about them. Of course it's a niche firearm and not for everyone.
