I have a pair of DMcKBs made for me about 15 years ago (I think). Used for a lot of driven shooting, never a mis-fire. This year, I left them the other side of the pond between seasons and thought I'd have them stripped, cleaned and serviced, if only because it's been a while since they left the shop. Absolutely no problems, but, at least, I now have fresh oil in the innards. A propos of Dig's comment, the only problem I know of with a pair of Boss SxSs made in '29 was a need to have the single trigger on one regulated once in the last generation. I believe the gold spring had to be replaced.These guns have also seen a lot of pheasants and partridge.
