I'm envious, I wish I could make that work. I can't even make appendix work on a small gun, Just the way I'm built, gut drops right over belt line and the gun has to sit right where my torso and thighs bend to sit.I started into the Sig world with a P320 Compact. I loved it. I was delighted to own a pistol from such a legendary manufacturer, and worked hard to get proficient in hitting what I aimed at. However, my eyes are 55 years old and I could see the handwriting on the wall.
I had seen the introduction of the RX and wanted one badly. The availability of them in the market kept getting delayed and so when I finally found one available in the Full Size at a time when I had the money to buy it, I didn't hesitate to get it.
I was not disappointed. I quickly learned to shoot it as well if not better than my compact since it seemed to be a smoother gun to shoot. I then began to notice how much faster target acquisition was for me with the red dot and how much more consistent I became with my groupings being more and more concentrated.
I was pleasantly surprised after finding an appendix holster for it that I was able to make it my EDC. That's right... a Full Sized 9mm with Reflex Sight and Surefire Weapon light is fully concealable as my every day carry and no one is the wiser.
I realize others may not feel the same way about a double stack, or a full sized pistol, but for me... this works just fine for me, thank you!
