My favorite carry has been a 1911 in .45 of course. In hot weather it is less practical and I carry a PPK in. .380.
I do love them both. Unfortunately back and Hip issues have made it difficult to carry the 1911 all day so I have fallen back to the PPK. I love the gun but I am wanting something with a bit more energy.
I am going to give the Walther PPS a try as a compromise. I am thinking that the 9mm PPS may be a good fit with Federal HST 147gr +P. Adequate stopping power without 3+lbs on my belt.
