Just funnin' you doc!
I was just going to suggest that very thing!
With the laser/holo/light setup I can shoot from about any position without having the perfect 'stance' and sight line-up you need for regular sights. In either the .45 Colt ('cowboy' loads), .357 Mag ('38 special' loads), or .44 Mag ('44 special' loads) configurations, you shouldn't have much of any recoil fired from the shoulder, but you won't NEED to fire from the shoulder if you do the laser/holo/light setup.
For the Rossi, the B-Square add-on makes for an easy setup and can be taken right off when you no longer need it. For the short-action Marlins there IS enough room for the Burris Fastfire-II and a LaserMax on a regular Weaver rail scope base, but I like the forward position of the XS-mount a bit better (I'd gotten it when I was using the much larger EoTech holosight that wouldn't fit on the normal rail). The long-action Marlins can ALSO be light-loaded, and have an even longer receiver to work with.
If you do the 'conduit' mount like on my Marlin, it's a non-gun-altering thing, but if you do the J-B-Weld one like on my Rossi, and you just have to restore it back to original, you could simply replace the magazine tube.
For any newbies who didn't get the 'inside joke', here's the pics:
My vote is that it's another excuse to get a nice little .357 carbine...
Good luck with the colon-polyp-that-got-uppity; getting yanked out, soaked in some formaldehyde, and sliced up in little bitty pieces hopefully taught it a lesson, and served as a warning to any others that want to mess with you. Be sure to get your followups, eat right unless it conflicts with your treatments (consensus is usually "fresh fruits & veggies, fiber, lots of vitamin D"), and any of you folks here who aren't getting colonoscopy screens starting AT LEAST by age 50 (I think 45 is a better age to start, statistically), need to do so. (Finding a colon polyp that is turning cancerous during a screening exam is like sneaking into the enemy camp the night before the battle, and killing them all in their sleep, vs. having to have a big battle the next day.
