^don't listen to him
you should instead look at this pack to see how to make good animations.
Let Tier+Tactical be itself, it has no proper reload animation anyway.
This add-on has hands on the gun to make it more realistic and the reload animation (if it gets improved) will make this as good as the L4D2 weaponset.
Your guns are too long in my oppinion, and the reloading animation sucks in my opinion.
We've already established that the weapons could be shortened earlier, along with an improvement to the animations
But to be fair this is an well made weaponset.
So please shorten your weapons for a bit.
I suggest you look at the L4D2 weaponset on how to make proper/good looking reload animations.
Thing about that is, the models were made by a guy who is near professional level in modeling. There's a small difference.
Another voice calling for the same thing might make a difference. ;)
