Haven't made a purchase yet but am looking seriously at a Ruger SR9c.
I say good choice. I have had one for about six months and haven't found anything about it that I dislike. It conceals easily, has a good trigger, thumb operated safety, striker fired and the rear sight is adjustable for windage. It is not a substitute for a target pistol but is accurate enough for any self defense range that you might find yourself in. I have put over two hundred rounds thru it with no malfunctions of any kind. Definitely would be my choice if I were doing it again.
Oh, not that it makes any diference but I am eighty, stand about 5'8" and weigh usually around 150. This gun is just my size!
And 9mm's have been known to maim and kill people. Just ask Trayvon. (ha)
