357sig is a lightweight short case length version of the 357mag. its on the same power level as lighter than 158grn 357mag loads. it was developed explicitly at the request of the texas highway patrol for a powerful auto loading cartridge with superb barrier and glass penetration qualities.
those requirments were needed because the thp often are having to shoot through car bodies and windshield glass. at this the round really excels. its an extreme over penetrator in some loadings.
loading for the 357 sig is not as easy as most pistol cartridges.
it is a fun cartridge to shoot and congrats to the OP on picking an excellent round
my opinion: its an excellent self defense round if barrier penetration is a real concern. its also a very good alternative to the 10mm. ammo can be difficult to find as its primarily a LE round. my thinking is skip it for normal SD use.
