I am pulling a Brett Favre here, been contemplating a 38 Super in a Commander sized 1911. The question is do I really need to add another caliber to the list? If I must have a Commander sized 1911 should it be in 45 ACP? I already have 45 ACP on hand along with reloading dies. For 38 Super I will have to buy new dies and more ammo but I can also get a 9mm barrel and shoot 9mm which I already have along with all the reloading equipment.
