Depends on the day and what I am wearing.
Most of the time (esp in this cold) I have my full size colt 1911 in an IWB in the 3:30 or 5:30 position (depending on holster) One mag is always in my weakside back pocket and sometimes I put an additional in a single mag paddle holster.
In hot weather I will carry my S&W 642 .38 spl in an IWB at the 3:30 position or in an ankle rig. Always carry at least one reload.
I have on occasion carried both. For instance my brothers car broke down in a bad part of 10th st and I went to help out. Colt on the hip with three spare mags, S&W in and ankle rig with one reload.
never do know about 10th St
Wow, I expected to see more snub nose's. Maybe I need to get a compact semi-auto.
