I'm still drooling over the idea of a modernized top-break like Vash's revolver from Trigun:
Beretta
makes the Laramie in .45LC so I know a break-top can be made to handle the stress. I've always liked top-breaks, it's just that they tend to be so friggin' fugly.
I don't care so much about a replica of Vash's gun above (okay, I do, but...), I just want a top-break in the style of a "normal" revolver and in a caliber less wimpy than .32 or obscure SASS loads.
Would also like a doublestack semi
and a carbine in 7.62x25. At least that'd be moderately useful as a cheapo-surplus (for the time being, anyway) blaster and poor man's FN 5.7 - unlike the myriad of .17HMR revolvers Taurus is producing for some reason (seriously, what is the use of a .17 out of a snubnose?)
Annnd last but not least, a new production 7.62x54R semi-auto rifle. I can't imagine anything more beautiful in my mind than a sleek black $250 Saiga paired with some hard-hitting 10-cents-a-round surplus 54R. Hello, poor man's FAL. Extra bonus points if it's styled after an M1A.
Oh - and a Hi-Point in .22LR. C'mon Hi-Point, make me a reliable, reasonably accurate brick of a .22 and price it under $100...
