    Ok. Be gentle but heres a Q&A

    So say I buy his parts just for POOPS and giggles. The guy that got the 995 parts without reciever.

    I have a perfectly good functioning 4095.

    So I mate the 995 BBL to the 4095 stock Then Load 357.

    Will this work?????

    DEAD seriuose guys what is the take on this>>>>

    All yhe info needed for a dumb question but with a Idea.
     
  2. My first thought is that one round is rimmed and the other is rimless. I do not know what kind of problems you would have to over come there.

    Second thought, the .357 is a longer casing and would that cause ejection problems?

    Interesting proposal though :D

    HM. I have only shot a 357 so I know nothing about them. :?

    Not a thing as bullet size, casing size ect. :?:

    But I think it would be worth looking into. Well at least sounds worth it. :wink:

    Are you talking .357Sig or .357 Magnum?

    i didn't think this was possible...
     
  6. My bad, I forgot all about the sig round. Well GM do you think there is a possibility with the 357 SIG?
     
  7. One problem w/ .357sig is potentially the pressures. However, the 995 IS rated for +p and +p+. 9mm(standard pressures) go up to ~33000 cup, Whereas .357sig goes up to ~38000 cup. So potentially you might could from that standpoint.

    Then theres the issue of case diameter. The removal of chamber material to make it fit may cause enough of a reduction in strength to make it no longer safe for the higher pressures.

    Also the .357 sig cartridge is significantly shorter than 9mm.

    It would have to be a swap btw the .40 and .357 sig. Most pistols that are chambered in one can switch to the other easily with just a barrel swap, the mags can even stay the same. I know Glocks and XDs can swap calibers between the 2 with just a barrel. I assume that is the 40 rifle can handle .357 sig pressures.

  10. Uh oh. if gman is asking for clarification, rather than just saying "No", ideas may be percolating in his head :D

    wow I didn't think it would be that close. even if the barrel idea worked wouldn't there be extractor issues?
     
  13. The physical problem I see is that they have different shaped cases/necks, and that is how a rimless cartridge seats for firing compared to a rimmed cartridge which uses the rim to seat for firing.

    If that could be overcome, and the pressures are similar, who knows? :D
     
  14. Ooops looked at the wrong measurements in my load book on that one
    :oops:
     
  15. You'd have to drill out a section with a lathe and put a sleeve in, then rechamber to .357Sig... Then figure out headspacing... Not sure how well a sleeve would hold up.

    Sorry if I missed someone else saying this but I believe the 357 Sig is just a 40 S&W necked down to 9 mm. I would think this would be a fairly simple conversion.

    It's possible but there would be a lot of work involved, Re-chambering to .357Sig, New Extractor, Bolt Face Modification, Spring rate, Bolt weight just so much work that its just not practical cost wise.

    why is it just a simple barrel swap on glocks? they use the same extractor, slide, springs, etc...

    Ya know, Gman, he's got a point. What do ya think? I can call a gunsmith friend of mine and ask him about it.... I think I will do that on Friday, I need to stop by his house and pick up some firing pins anyway.
