I received the holster quickly from Alien Gear, put the longest screws and spacers in and the gun was still pretty tight. I loosened the screws to the point they were ready to fall out and couldn't draw the gun while wearing the rig. I set the holster to highest ride position to see if it would help. No dice. There were rub marks, almost scrapes, on the lower front outside half of the trigger guard of the gun. After taking the holster apart I could see where It was getting scraped by the trigger guard. I dremeled down the kydex "bubble" inside of the trigger guard area of the holster then sanded smooth and oiled it. I had to remove quite a bit to make it work. The Sig draws easily wearing the holster at the 4 o'clock position and retains well now without having the screws so loose they're falling out. Now that I'm done adjusting it I'll blue lock tight the screws. I haven't had a chance to wear it much yet but I think I'll like it.
