Hi all. I'm new here,and new to hand gun.But i am interested in getting a S/A gun.Looking into 9mm.I am going to a gun range this week end and i'm going to try out a few different guns to see what feels right. But i'm still not sure what to look for.Is the Glock right for me?Maybe another brand? I did hold the Glock and felt ok.Is there any other brand i should consider to try? I looked at the 17 and 19 i see the difference in size but is there anything else that i need to know between the two? Thanks.
