Good choice, I was lucky enough to find an unfired Mauser HSC in .380 and also have a Kahr K-9 and S&W 66-1 so I’m covered with lil stuff. The Colt Commanders goes in shoulder holsters and Glocks in pants.
I got it for a really good price, too. It was much less than a Ruger LCP and IMO it's a much better weapon. Granted it's a bit larger, but I'm much more willing to trust my life to a Sig design than Ruger's attempt to 'improve' on a marginal design.
Just my two cents. Your mileage will most certainly vary.
