I love the Marlins. I currently own a '94 in 44 mag that has been modified - 16.5" barrel, shortened length of pull, trigger job, upgraded sights, skimmed down forend, etc.
The 1895 is a bit bigger, longer and heavier than the '94 and the Winchester '86 even bigger still. The reason I suggested the '86 is becuase it's a top eject rather than side like the Marlins. Being a lefty, I'm not sure if you'd eject the spent case into your face with the Marlin. Something to consider.
Another solid option, with a bit of work, is the Rossi '92 in 454 Casull with 16" barrel. This option is basically a scaled down version of Winchester's '86 and is also top eject.
