    1911: which slide for .40?

    I have a line on a .40 barrel for my 1911.

    Will that barrel work with a .45ACP slide ? Or a .38Super slide ? Or is there a dedicated .40/10mm/357sig slide out there ?

    I'll have to look but I think the hood of the barrel is the same for a .40 as for a .45, about 0.415" wide. This is the portion of the slide that butts up to the breach face, assuming your barrel is not a ramped barrel. I know the 9mm and 38 super are narrower. I do not know of a dedicated slide for these calibers. I know that each installation requires tweaking the recoil spring.

    I just checked the hood dimension of two barrels here. .38S = .350", .45=.410".

    Wish I had a .40, .357, or 10mm barrel to check :-) Anyone ??

    Sorry, buy I sold off both my .40S&W 1911s.

    Tubby45 has a Kimber in 10mm, if the OP really wants to know, I'd send him a PM if I were you.

    Contact Bob Serva of Fusion Firearms and go with what he says as Bob knows 1911s. A word of caution is I have been playing with a Colt 9mm conversion for five months, it has had reliability issues. This Colt is on vacation with Ten Ring Precision/Alex Hamilton right now. Regards, Richard

    Remember that the cartridge needs to

    #1 ~ be able to slide up the breech face cut.

    #2 ~ Be able to be tensioned/secured in the breech face cut by the extractor during extraction and for ejection.

    So methinks you need to buy a .40/10 slide. Go to Fusion Firearms.

    There are 3 pages of slides. Great quality.
