Possibly a problem in a couple of situations during close contact. Visuals could be a problem too. The locked back slide of a 1911 could be a visual indication of an empty weapon if seen by the enemy, but I've never heard any mention of that. The raised toggle bolt of the Pederson rifle would have been very obvious to an opponent if that rifle had been adopted.
