Having owned several of both over the last half century, I would say that the stock configuration between the Miroku and the Browning is quite a bit different, the nearest being the current 725/Mk38 sporter. The 325/425/525 were all a lot different to the Miroku's. The Miroku always seemed to have a nicer stock in comb height and grip, for someone like myself, who has small hands. I am currently using a 725 black thingy, but I do struggle a bit with the palm swell. All of the Browning interchangeable pads are great for those with Gorilla arms (they start at 14 3/4" and go UPWARDS). If, again like me, you need 14 1/2" stock, you may need to change the pad because the standard squidgy thing, can not be ground down ! (hence mine overhanging at the toe ). Some of the game Brownings still have the curved heel on the stock, which will need cutting straight to fit any recoil pads. One of the problems with the game Brownings, would seem to be felt recoil. I would certainly want to try the gun before deciding, remember, even guns of the exact same make and model can all feel different to each other, especially when you come to shoot them. As above, I have fitted a rubber recoil pad on my 20 bore Heritage, I warmed the pad up in boiling water prior to screwing it onto the gun. The pad then took on the curve of the heel, when on the stock.
