So many 1911's and glocks out there! I'll stick with my CZ cloned Tanfoglio Witness full-size in 9x19! And who says you can't carry a full-size concealed? I do, everyday.
Summer carry means cargos/khaki shorts, or jeans shorts till October 1st! (during work wear long pants though). My preferred carry is a G19, OWB, and a BUG, S&W 442 in a pocket or a IWB/weak side or sob. Usually carry an extra G19 mag, and tactical knife clipped weak side.
Sometimes use a nylon shoulder rig(G19), depending on cover shirt.(patterened-plaid, or blue jean-blue work shirts.( Have a Hawaiian one, but it is getting dated since Magnum PI reruns are back on! I only wear my Detroit Tigers cap around the house, LOL) Wifey thinks I am losing sanity.(have a 1911 like Magnum in 45ACP)
used to carry a east german mak concealed, S&W model 10-6 open, I kept a cz-82 in my nightstand and now it inbetween my passenger seat and center console when Im in my car most of the time
In winter I can carry my XDm 9mm on the hip or under the arm without much trouble. In the summer it's just too large and unwieldy so I rely solely on my Bersa BP9CC IWB... can't even see that trough a t-shirt! I'm a total leftie so my choice of handguns can be limited without spending a fortune modding one for left-hand. Ironically though my non-dominant hand aim is pretty much equivalent as my dominant hand, just don't expect me to be able to release the mag or anything without dropping the gun.
