Howdy,
Taurus PT 111 (9mm) and PT 145 (.45). In the summertime, I use DeSantis Nylon holsters for the 9mm, and can conceal this quite nicely. I also use an ankle holster when wearing baggy jeans or sweats. In colder months, I'll carry the 45. The PT 145 is one of the smallest (if not smallest) 45's that will carry a double stack with 11 rounds total.
Thanks,
Tony
