I have an AD in 38 and a Bond Mini in 45.
The AD is a very nice gun and does resemble the original Remington. With the AD you must remember to manually set the safety on before closing the gun. The safety automatically disengages when cocked. The AD I have only hits half the top firing pin with the hammer shuttle. It finally broke and wouldn't fire the top barrel. Ordered a replacement part and it only engages half the top firing pin. I have examined 2 other AD 38"s at gun shows and they had the same issue. However it is a beautiful gun and I had mine engraved by Kelley Lassiter and put real elephant ivory grips on it. Very beautiful river boat gambler gun now.
The Bond Mini 45 is about the same size as the AD. The Bond Mini has shorter barrels and is slightly heavier. Recoil on the 45 Colt Mini is stiff but controllable. I'm going to order 38 barrels for it. With the rebounding hammers you don't have to engage the safety before closing the gun. But with the Bond it is manual on and manual off safety. I haven't encountered a weakness with the Bond. The Bond might come with the competition kit installed but I still cut 2 coils off the main spring to improve hammer pull. The Bond still fires reliably.
Shooting a 16" plate target at 5 yds isn't an issue with either gun. Barrels do shoot to different points of impact on both guns but not enough to be an issue at 5 yds. I do prefer the Bond Mini over the AD. I do like derringers and have shot both of mine a lot but not in competition. I just shoot them at the range plinking etc. sometimes as many as 200 rounds through each gun.
I will take some pictures of the guns side by side. Never have posted pictures before but if I can't figure it out I will email pictures to folks that know how.
