Nice carbine!
Three in .45 ACP?
I agree, it sounds like it would have sold VERY well even though Marlin's attempt at a pistol-caliber carbine seemed to flop somewhat in terms of popularity/sales.
A number of years back, I fired one in 9mm and was less than impressed due to the weight of the rifle vs. the caliber but I think I would like one in 40 S&W.
J&G Sales (as advertised in Shotgun News) usually offers police trade-ins (40 S&W) at decent prices.
