Half-life 1 Weapon sounds: MP5

Not from me but in steam workshop there should be from others

is there any shoot sound mods that i could get

I haven't tried it, I don't know. But you can try, it doesn't break the game

snd_rebuildaudiocache. do this work?

Usually deleting the cache fixes the problem, but in L4D2 it doesn't work. Verify games file won't help. You need to google this because there are many methods for solving this problem. In general, it is possible that I did not guess with the problem, I just assumed because many people had this problem, including myself.

should verify games file work? are there any other way u know of?

I do not know the name of this problem, but most often it happens due to the fact that either Steam downloads mods in the wrong place, or the game cache is buggy

what should i do to fix this issue? what is this issue name exactly?

Just checked the mod, it works without problems. You have some problems with the game / steam, this is a common problem

sadly mp5 reload sound only mod is rare. i cant find another just like your
