    Can you fire 45 Super rounds from a 4595 Carbine? Just trying to find the limits of what I can send through the barrel.

    I wouldn't. The gun probably is good for it, but the energy in super is higher and the bolt may open while there is still pressure in the bbl

    It has been done in a JHP (by DUSTER) and a heavier recoil spring is
    a great idea, and I would maybe try and add weight to the bolt, too...

    My JHP survived about 35 rounds. A detailed magnified inspection showed no damage. However it was low level magnum like recoil and I could feel the slide slamming in the frame. The gun wouldn't take it long imo. If you like your gun I wouldn't.

    What about adding some sort of buffer for the slide? Like the Marlin Camp series!

    Damn now I'm gonna sound like a gun snob.

    But really why do this? I did it as a torture test, not an attempt to use 45 Super. When I said I could feel the slide hammer, I meant HAMMER. I would suggest if you want a 10mm save up and buy one.

    Or...they MAKE .45 Super guns, too.;)

    However, for the sake of discussion...the .40 S&W is about 35,000 psi in chamber, and the .45 Super is only 28,000 psi as far as I can find.

    So...since the 4095 and the 4595 are basically the same...if you COULD overcome any issues with the bolt hammering the gun, it "should" be a decent way to go. IMHO, of course.

    Someone with some engineering could probably determine if the bolt thrust is "too much", but realistically... the .45 Super is pushing 185 grains at 1300 fps, and 200 grains at 1200 fps, while the .40 is doing either at about 1050 fps but with higher pressures. Seems like it "should" be able to handle it?

    Here's my OTHER question...how does a .45 bullet at 185 grains get up to 1300 fps out of .45 Super with only 28,000 psi, while the .40 180 only gets 1050 fps despite going up to 35,000 psi?:confused:
