I have found in weapons.meta file that there was also a smoke grenade launcher .So I decided to make a mod for that.I know that it is not a big mod or was hard to do but some will appreciate it.
Now you can have it as addon and not replace the original one.
Big thanks to @GeorgeZhang for helping me out.

And also big thanks to MTZ for letting me edit his mod and upload it with my mod. His mod is in the link below.
