Welcome aboard Blue J!
You will find great people on this discussion forum and many of them former military such as myself (Marine). A little about myself. Just turned 21 on Feb 3rd and a few days later I purchased a SIG 229 in .40 which I carry just about everywhere. At first I was nervous about OCing as you were but the worry goes away the more often you do it. I started by going to gas stations, fast food, 7-11's those types of places before I started going to larger facilities. I am married and my wife is also on this forum under the name of marinewife. We are trying to find the "perfect pistol" for her which is becoming quite difficult as she is quite picky. Anyways, enjoy the forum and OCing, carry on!
