I had moded the weathered 10 mm pistol with a laser scope and when I equiped it and looked at my character in the third person view there's a huge red box with a white exclamation point that envelopes my character. When in first person mode the screen looks washed out from the whiteness of the exclamation mark and the gun isn't in my hand. Please address this and similar issues in the next patch. Thanks.

this has happened to me too. You can't put weapon mods on unique weapons and i guess the weathered 10mm is considered one. Hopefully u have a save before you put it on ur gun. Also your not suposed to even be able to add it, apparently its a bug.

Where did you get the laser sights??

:sadvaultboy: My PS3 version has the same gun mod problem, I like this gun gun but can't use it! I added the extended mag to the 10mm weathered,Please get patch sent out, ghouls to kill with my bonus gun! thanks.... :cryvaultboy:

this has been covered already. you aren't supposed to be able to mod that weapon, there are no textures for that weapon with those mods

I know that you aren't supposed to be able to mod that weapon but theres is nothing to stop or warn You.. the mods are for 10mm pistol. where is the patch to fix this?

i keep seeing this problem on the forms. i had it too. i fixed it. just delete the dlc then go in the game and save, redownload the dlc and when you go back in the game it will give you all of the classic pack again. your mod is lost forever though. small price to pay to have your gun back instead of a left over prop from metal gear.

It's a known glitch. You're essentially putting a weapon mod on what is considered, apparently, an unique weapon, which you aren't normally able to do.
