Hard for me to say as I carry what fits the day,time ,weather,dress code, I like my P11 w/ the .357 Sig conv. the best. Just switched it last week to the .40 conv. and normally always the .380 as a bug. If it's cold enough and clothing permits I'll have the PT1911 on. Also have a few others I rotate into the mix (but only if I have the range time to keep practiced up w/ them.)
