I've carried a 60 no dash and a 60-7, both with 1 7/8" bbls for several years now. According to Smith & Wesson reference tables, the 60-7 is able to handle the +P loads. I recently acquired a 60-9 with a 2 1/8" bbl in .357, which I will load with the +P loads as well. I've been carrying in my back jeans pocket, which isn't the best idea but it has certainly been serviceable. I got an Uncle Mike's pocket holster with the -9, which I have been using for the -7. I want to upgrade the pocket holster, although the Uncle Mike's has been fine.

Blessings,
Hog
