I have owned my Sig P320 XCompact for about 6 months now. I started using it as my EDC at once. I have used Crossbreed IWB Holsters (Super-Tuck or Mini-Tuck) for 7 or 8 years now. they holstered my Sig 238, then my Khar P9. This pistol is the best EDC I had, meets all the requirements. I used it with a Crossbreed Super-Tuck IWB holster in my usual 4:00 position. Great, comfortable and accessible. Then I ordered the ROMEO1Pro. After waiting the 4.5 months it was on back order I got it and mounted it. My holster troubles began. I bought the Crossbreed cut away version of the holster I already owned and used. Figured, No Biggie, same holster just accommodates the sight. Wrong. If you prefer carrying IWB, there is a problem with the fact that the best position for the pistol places it fairly deep into the pants past the belt. Unfortunately, the red dot protrudes about 3/16" out from the slide. This means that it will catch on your belt before the pistol can be properly seated in the holster. First thought was to use a belt clip combination that would raise the pistol's position above the belt. I did and created a belt clip combo that raised it up to at least 1/8 to 3/16 above the belt. Problem solved, right? Wrong. This set up raises the overall pistol position so high that the grip is both uncomfortable and obvious. I have had multiple email exchanges with Crossbreed. They have been wonderful. Offered full refund even though I bought it nearly 6 months ago when I ordered the ROMEO1Pro Red Dot. Unfortunately, their solution is no different than I already tried. Raising the pistol. For me if it leads to an uncomfortable carry, it's a no-go. One should be able to generally forget that they are carrying if you have a rig that is set up right. That can't happen if it is either poking you in the ribs every time you sit down or patterning itself under your T-shirt. I am sitting here writing this while the Epoxy cures on a hard rubber spacer I have glued to the outside of the Kydex. I believe it will allow me to set the depth as usual, yet hold the belt away from the edge of the Kydex just enough to allow the optic to clear the belt and allow the pistol to seat. We shall see.
