I have one of the extra lite deluxe models. Miroku makes one hell of a rifle. Also own a 1895 in .405 Winchester built by Miroku. Never had any issues with the rebounding hammer or feeding or ejecting with either.
I did have the throat lengthened on the extra lite 45-70 by about 1/4 inch.

My biggest fear is when I die my wife will sell my guns for what I told her they cost.
