For a 1911 pistol what length (I prefer longer barrels) makes most sense between sight radius and cartridge performance? I am not wanting the hottest loads just common sense loads for job needed to kill deer about to 75 yards? What about the 45 acp, is 460 roland a good option on a 1911, how about 10mm and does the 40 S&W come into the play? If a thread is here about this please give me the link! Thanks
