Do any of you have a Glock 17L? Or have you ever shot one? I'm thinking about getting a 9mm for plinking. I already have two Glock's, a model 22 and a model 27 (both 40 S&W). I like the idea of the six inch barrel on the 17L. Other then barrel length, whats the difference between the model 17L and the model 34? Thanks. :-)
