If you like the 3at, you will really like a PF9. I bought a PF9 for my daughter, she likes much better than the 3at that I had. She liked it so well that I bought one for myself. Recently traded in my 3at because I had quit carrying it. The PF9 is easily concealed, I have a Galco pocket holster that works well in baggy pants and IWB tuckable for other carry.
