I pre-ordered the game, so I got the classic pack. I went to gunrunners and bought a 10mm laser sight for my Weathered 10mm Pistol. So I put it on, but I didn't use it right way. I went to Freeside and took it out incase of thugs, and it was a gigantic tilted square, with a big exclimation point on it. I dropped the gun, and couldn't pick it back up. It just sits there like a big error sign. Is this just for the Weathered 10mm Pistol?

Thanks for your help.

For the moment untill it gets patched up, there's a mod that fixes this error, the mesh for the modded weather 10mm is a bit messed up at the moment linkz to the mod http://www.newvegasnexus.com/downloads/file.php?id=34794
