I am not here to try and sell anything to anybody. I am simply stating the ballistics of commonly carried bullets out of commonly carried guns.
A 124 grain standard velocity 9mm HST out of a Sig P365 3.1" bbl moving at 1100 fps generates about 333 foot pounds of energy. The same round in +P is 364 ft. lbs.
A 158 grain Buffalo Bore +P Heavy SWCHP moving at 1,000 fps from a 2" bbl generates about 350 foot pounds of energy. That's about the best 38 special I know of.
The difference in energy is not enough to practically matter, however the violent recoil out of a J frame & only 5 shot capacity is dismal against an 11 shot, 17.6 ounce (unloaded) 9mm that is slimmer, lighter, smaller and holds more than double the capacity. Recoil is mild and so follow up shots are easy and fast.
If you are truly intent on improving your EDC platform, this is something to seriously consider. I was a revolver guy my entire life (for EDC/CCW) but that changed about 4-5 years ago when the Sig P365 came on the market. If you objectively compare a Micro 9 (Sig, Hellcat, FN Reflex, etc) to a 5 shot J Frame, there is simply no contest - at least in my mind.
