In 2018, Sig Sauer introduced the P365, a micro-compact 9mm– really the first in its class– that delivered a 380-sized carry pistol but with a 10+1-shot capacity in 9×19 rather than 9x17mm.
It was the talk of SHOT Show that year and the gun has gone on to become one of the most popular carry pistols since then, sparking a flurry of imitators from Ruger, S&W, Springfield Armory, Taurus, and the like. Hell, even Sig has almost a dozen different models of P365, all cannibalizing the same marketplace, which is now bordering on oversaturation.
Speaking of which…
Meet the new P365-380, which is the same size (albeit three ounces lighter) as the 9mm version while only having the same magazine capacity (surely, they could have crammed an extra round or two in there?).
Sig says the design philosophy for the P365-380 is to offer shooters– especially those with smaller hands or those that find the manipulation and snappy recoil of small 9mm pistols challenging– another option.
Plus, in my opinion, it also opens markets such as in Latin America and Europe for the P365 where 9mm Luger is banned for civilian consumption, reserved for military and use, but .380 is allowed.
For a similar concept, look up the Glock 28, which sells great overseas but is restricted in the U.S.
