Wow, I like the English NE #1 idea as well as the 32-20/32H&R combo.
I want a Deefield in 45 Win Mag with a 10 round box mag (I am sure that if it were available, i could get the folding stock and rail mount on the handguard), a #3 in 460 S&W, a 5-shot GP100 in 45 ACP, a factory 5-shot Blackhawk (45 Colt, of course), and in the non-.452 dept., bring back adjustable sight .40 S&W Blackhawk with a .400 Cor-Bon cylinder.
The thought had crossed my mind that if Ruger can make a 4 round mag for the Deerfield, they could get as 5-7 .357 max in a rotary mag and build on the Mini-14 receiver. Of course, there are two .44-.357 wildcats out there already and a barrel change is not out of the realm of possibility for the enthusiast.
