All Randall models, from forging to forging, have the possibility to be slightly different. My most recent Model #10-5" appears to be smaller than my last. The scales are more "rounded". #10's are not forged and stay more consistant than other models. I had 2 pieces of handle material rejected, this past month alone. due to being over-sized.
The shop is quite specific on material and sizing allowed for each and every model. You won't notice very much of change...just slight change.
Hope this helps, Capt. Chris
