I think Browning was ahead of their time and really on to something with the 20 weight guns. aluminum recievers were radical in their day, common weight savers now, balanced like a double', graceful small Prince of Wales grip. the external trigger block is actually easier once you get used to it, and much more accessable to hunters like small women and kids, who can reach it easier, especially with the smaller daintier grip. I have had individual guns which weigh less than 6#'s. look for cracks around the barrel reciever junction, it's from misadjusted guns firing heavy loads, resulting in over recoil travel of the barrel. Same with the M-59 Winchester.
