About 90% of gun fights are at 6 feet or less. This is the Rolls Royce of small weapons. Follow the links at the site.
I sometime carry a 9mm Glock, but only using my Thunderwear holster. The only one, I have found to conceal. Also, for me more comfortable. Add plus, more women will hit on you.
Every cop I have meet at the range has wanted to buy my Seecamp from me for a back up or off duty carry. It ain't for sale.
My guess is, like me, you'll go through owning lots of guns and holster before you find what is comfortable for you.
