It's a great gun for plain clothing that you can't conceal a large frame pistol. I'm not sure why people think the .380 is a poor defense round when it is deadlier than a .38 spl from a snub nose. That of course is due to short barrel length, thus lower velocity. You can check the Strasbourg tests for more info.
If you use 7 rounds of .380 ACP on someone close range... It will get the job done. Anything worth shooting once is worth shooting twice. Handgun rounds are not very good at quick one shot kills.
