OK I have a glitch or something like that for the weapon mods. I preordered NV and got the Weathered 10mm pistol. I soon came across the Gun Runners next to the Strip and bought a lazer sight and a silencer for the Weathered 10mm Pistol. after equipping the mods to the gun, something strange happened. I pulled out the gun to see the new weapon, but my screen became a white blur (imagine turning the brightness on your monitor all the way up). So my character had his hand up as if he was holding the weapon, but no weapon was in the hand. I zoomed out into the third person mode and found out that the white blur was from an exclamation point inside a red daimond that was on top of my character. What just happened? Is there data missing for the lazer or silencer mod that is causing this error? Is the Weathered 10mm Pistol unmodifiable? (if that is even the right word) I can take a screencap and post it later when I have some time, and hopefully that will clarify what is happening. I didnt think of it until now. (I am a dork) Is anyone else having this issue? I have modified other guns without getting this exclamation point error.
