I cannot reproduce this "bug" so I suspect you're using a flash/laser light mod for M1911 and/or M45A1, but the mod is simply not compatible with "my" aka REH_BlackJack's pistol mod because the light is in a wrong position unlike the in-game default light model. Someone requested me to publish this pistol mod without its flash/laser light, and this is what I did, there's nothing else I can possibly do, probably not even allowed to modify this model either (Edit: He took the model from a different game, I forgot), and I'm not familiar with creating, modifying or porting models at all. This is why I recommend using the normal version.

M1911 and M45A1. Again this is the version without the flashlight and laser model made for this skin.

Is this just for the 1911?
