IIRC the 10 gauge receivers are a bit thicker than the 12 gauge (and under) receivers, However since the standard stocks on Handi's are "proud" and stick out a bit on the sides of the receivers you should be GTG, everything else is the same on all stocks, bolts, angle, etc. If you have another Handi, either a shotgun, centerfire rifle, or even a rimfire, with a standard wooden buttstock, it is easy to swap out the stocks and check for fit....<><....
