Short LOP. And adding a pad to get to 14 1/2" will also add more drop.
But otherwise agree that those are nice guns. Passed on one at what used to be a very good Kansas City show (held twice a year). Think I could have bought it for low teens, but wasn't looking for a 12ga at the time. Friend of mine bought one like that (but without ejectors) on which someone had installed choke tubes.
Not sure I've ever seen a poorly made gun from Miroku.
I have one. Mine is colour case hardened and very well finished. Decent length tubes (28"). Chopper lump construction, hand engraved, Drop points, gold inlaid "SAFE" and wedding bands to the breech and a Stock Oval. I had it restocked to 14-3/4" LOP and a higher comb. It was 14-1/4". They command high prices in the UK. Gough Thomas wrote an article in "The Field" giving them high marks for quality.
