I like how you do your animations. It's defined in a way. Although I think you really rushed this pack. It's not smooth although I know you can do it.(i'm lazy too xD).
Since there's no ik rig in MS3D, you need to pay attention to the aesthetics of the hands, especially the fingers. Check how you hold and grip in real life. The v_crowbar model, has the thumb on the right, look weird although, it's not bad since it's not noticeable in-game.
Your deploy animations are edgy. For the 357 draw, I suggest that you also move the hands a bit, rotating it to left, then going right to give it a nice touch. Check HL2 draw animations.
I like the 357 so far, the crowbar and the tripmine.
Your pack is AWESOME. But the 357 now does that little clipping when reloading even if you are not looking downwards. The gauss FOV also looks pretty weird and makes it clip when drawn but it is a very slight arm clipping almost not noticeable which also happens with the grenade during the pinpull. The pistol slide doesn't move either but it think it is intentional
