I have a full size M&P with a Surefire X300 Ultra. I was doing a lot of research on holsters and what attracted me to the Griffon were the progressive belt loops that can accommodate different belt sizes, the ability to put the gun in the holster without the light, and the looks of the holster. Now the website says that the holster can accommodate the X300 and the X300 Ultra. The holster is terrible tight when the light is on the pistol. It's perfect when the light is not on the pistol. I have noticed where the contact points that could be the problem preventing easy draw and reholstering. But for 120 bucks I was hoping for no pains at all. Does anyone else have these same issues with this brand of holster? Is this normal for kydex holsters? If yours was perfect out of the box, what brand was it?
