i don,t think sig needs to build a 380 in response to the Body Guard 380. it would just be over-priced and likely a fat double stack. nobody is making thin single stack pistols right now, the market seems to be begging for higher capacity. whatever you can conceal comfortably with the highest capacity is what non Law Enforcement Carriers are looking for. i am usually carrying my Shield+, sometimes my G36. but if i am going somewhere where people might be uncomfortable if i am found to be concealing a gun, the thin little BG380 is not going to be found by anyone short of a pat-down. i have used it enough to be proficient and it has proved reliable. options for Concealed Carry are a good thing
