Three guns with this pack:
460s&w magnum with the long barrel and muzzle brake for long range large game hunting with handgun. (Similar looking to the 357) holds 5 rounds classes 4 through 9 and can use rifle scopes
Second: a .500 linebaugh magnum single action revolver modeled after the BFR (big frame revolver) for better performance on large game than the 454. Holds 5 or 6 rounds
Classes 5 through 9. Iron sights only, similar reload to 45 cavalry revolver
Third: mostly as a defensive handgun against wolves, tigers, etc: a 1911 platform in .460 rowland (basically a longer case than 45acp but has been used effectively against brown bears and is used for large game handgun hunting) holds between 8 and 10 rounds. Better performance than 10mm maybe class 4 through 8 but works for 9 if needed. Should be able to use the same red dot optic as the 10mm
