I just got my Enigma yesterday. Wore it for a few hours today and I can get it very comfortable (at 11:00 as a lefty) but when sitting for a while the muzzle digs into the groin area. I am going to get a wedge also. It is totally concealed with a t-shirt and sweats. If you aren't on their FB page, check it out, there are a lot of other wedges people are using or they are making their own. I forget, but I think they want $30 for their wedge kitI picked up an Enigma and set it up for my CZ Rami; it definitely wants to aim at my tender areas. It looks like I'll need a wedge to tuck the grip in and get the barrel pointing away from my body. Two o'clock will probably be my comfort spot.
Phlster just came up with a wedge kit on their site; I'm hoping I can use it to get the ergonomics right. I think some of their holsters have the wedge built in, but I had to use a different brand, and adapt it for the Enigma setup.
Now that the weather's turning frosty, OWB solutions are looking more manageable. I'm also looking into a shoulder rig.
