I'm leaning towards nothing can hurt a Mark 23, but does anyone know if I can shoot 45 super in it?
I have also considered 460, but only in a 1911. My reason was that I couldnt find a bbl for the mk 23. It seems to me that a Mark 23 if set up properly would be better suited for it than a 1911. If you do this, I would be very interested to know how it works..460 has the same OAL as the .45 ACP. The actual case is longer, though. This is done so that you cannot accidentally drop one in a .45 barrel. There is some *huge* pressure in the thing. In general, .460 R barrels are comp'd to make up for what just cannot be done with a heavier spring. And now that I am thinking about it, why not? Get an after market barrel that's already extended and threaded and mount a comp on the end. Ream the chamber to accept the new round and giddy up. I've got a Springfield 1911 that I converted to .460 Rowland that is one helluva pig dropper. I would imaging that this bad boy as a Mark 23 would be just stunning.
Side note: the RBCD rounds for the .460 are, for all intents and purposes, miniaturized RPG's. Just sayin'...
Yes out of the full size although if you plan to shoot alot of 45 super, you might need to upgrade the recoil spring. The Mark can take it without modification...I have never been interested in .45's till coming to this place. lol I love my 9 & 10mm's but the sheer idea of a Mk23 and a .45super or .460Roland just makes me weak in the knees.
Can a standard HK45 or USP45 (in any version) handle the .45 super?
The video is good, and the info is there but....Yes out of the full size although if you plan to shoot alot of 45 super, you might need to upgrade the recoil spring. The Mark can take it without modification.
