It's always a good idea to bring a backup pistol. Things break. You don't want your whole day wasted if you have something go south on you.
I will be attending the Gunsite Pistol 150 at Lebanon next weekend. I will be using my 9mm XDM. Should I bring a back up pistol? My XDM has never failed me and I have about 600 rounds through it. I have a 5" SA 9mm 1911, but no holster or mag pouches.
