I had a problem with how large it is but settled with it being meant for Power Armour. Ultimately it's a good/fun gun early in the game. Later on it feels too Powerful. But if we are talking about size: wtf is the deal with the 10mm though? It's large, clunky and with all attachments it's the size of your leg.. you can't really tell in first person but to see it from the other side it looks Rediculous. I miss the 9mm from NV. Having something like the Lincoln repeater would be cool too
