Depends on how you plan to carry it. IWB, OWB, or possibly even pocket carry. I have a sprinfield XDM 9mm compact, it carries very well OWB (I don't like IWB at all, it's simply not comfortable regardless of what holster I try and I know it's supposed to be comforting not comfortable, but that method for me is just plain painful, my back muscles just tighten up) Although I did find that if I use an IWB holster but wear it between my belt and pants, it conceals (bulge wise) equally as well, you just need a longer shirt to cover the bottom of the holster. I also carry a HK 45c using the previously mentioned method. But most often I carry a Ruger LCP (.380) in a pocket. VERY easy to carry you literally don't know it's there. IF the LC9 had been out at the time I got the LCP, I would have gone that route. The last time I was in a gun shop I checked one out and it fit in the pocket of the shorts I was wearing with no problem, jeans I'm not so sure, but it is small enough to carry all 3 ways with comfort. If I were only getting ONE conceal carry gun that one would probably be it. There are pros and cons to every firearm, but if you want to comfortably carry all day, the lighter, thinner, and less bulky the better. Plus the price on the LC9 is great, you're only looking at about $350 brand new. And if this is your first, trust me, you'll get more lol....
