I've bought, traded and borrowed lots of handguns to find what I liked best for everyday carry. The finalists were the S&W Shield, Kimber Solo, Kimber Compact ll, Springfield Armory XD-S, Beretta PX4, Kahr CT9, Sig P238 and the Ruger LC9s/Pro. Sorry Glock fans, I know they are super reliable, but I've tried and tried to like them and they just don't fit me. The Ruger LC9 is what I carry, nothing else disappears on my belt like it does. The specs say it isn't that much different from several of the others, but it just feels smaller and flatter than any of the others, at least to me. I've had mine about 7 years now and it has never had a single jam or misfire with 124gr or heavier ammo, it doesn't have a lot of problems with 115gr, but will occasionally fail to feed. I've found that true for lots of small 9mm pistols, specially the Kimber Solo I had. I like to shoot and try different guns and will continue to do so at every opportunity, but for now the Ruger LC9s is my main carry gun.
PS, the LC9 is now discontinued, replaced by the EC9s, basically the same gun.
