I have 4 guns I carry routinely
The gun I carry is largely dependet upon the weather and choice of dress (shorts, jeans or regular trousers) here in FL wher it is hot and humid most of the year. My 4 favorites are my Kahr P380, Kahr PM9, Walther PPS 9mm, and S&W 340PD 357 mag. The P380 is small, light, and oh so easy to conceal, but I like the caliber of the PM9 much better. The PM9 is small and easy to conceal, but not as easy as the P380. I carry the Kahr's in my front pocket. The PPS is incredibly thin, and very accurate, but somewhat larger and heavier than the Kahrs. So, I usually carry IWB. The 340PD is perhaps the best compromise very light, easy to conceal and carry, but is absolutely brutal to shoot when chambered with 357 mag ammuniition.
