Selbstlater 1906
This gun takes 3 shots to kill at all ranges, which is nice. This gun only has a 5 round magazine, which cancels out all the niceness. The 1906 is mathematically not capable of taking out multiple enemies, which is unfortunate considering how often you see multiple enemies on a 32 vs 32 player battles.
There is not really a variant that makes this weapon viable, and the Medic has better choices for every situation. If you manage to win a gunfight with the 1906, you better hope that the second enemy is using a M1903 Experimental. If they are, you’ll have plenty of time to reload.
