I bought one, because of all the talk about them and trying to 'justify' one was easy based on what I read.
Was not for me.
I can appreciate the simplicity, however they aren't all they are hyped up to be for a pocket gun - in my experience, and in a SmartCarry it would hang up on the draw.
As far as reliability goes, I've never had a problem with my semi-autos... guess I'm lucky or just buy good guns by manufacturers who don't have a track record of selling guns that don't work.
Everyone told me I'd miss my revolver if I got rid of it, I don't... at all, just wasn't for me. That said they ARE great guns and do have some advantages, (being fired from the pocket, etc)... but eh, I'll stick to my pistols.
