Faciously....(supposed to mean "humorously ")......How about converting it to belt feed??? The early Russian .50 gun had an open topped cylinder into which the cartridges were stripped by a feeding pawl. On your 29-, simply mill the tops off each cyl. bore....... use a flat sheet metal bottle opener to scrape the rnds out of the belt into each open milled space.....add a 48" finned barrel, a two wheeled cart......surely you can fan the hammer ala Bob Munden.......then you can go afield for game of any weight.....looking something like this;
Seriously........ I kinda agree w/the satin/blk hard chrome. I had a really tacky Luger done in that finish in 1966.......no idea where.....would have been a Shotgun-News advertiser.....did the Luger iridescent gold on the trigger & other small parts & I could hardly get it back from a gun shop clerk some time later.
