zehyani, you may wish to have him look at the European Brownings, specifically the 425's. They do have the requisite forearm, bbl lengths, no porting, standard Browning Invector [NOT plus]choke tubes, wide rib. The stock dimensions are good. The grip is not overly tight and could be rounded and thinned without hurting anything should that be necessary to meet his need. The stocks are oil finished. I have small hands & have not found the grip on a 20 that I have to be the least cumbersome. Andrew Litt in Wales would be a good source for one of them. They are good solid guns for the money and would meet his cost criteria.
