I play as an axis covert ops with K43. Now if I get into a close combat with an enemy I kill him with my rifle, unscoped of course. When I was new to the game I always used the luger but now I know that it is best to use the rifle, this is why:
-Luger has 8 shots in a clip, K43 has 10.
-They shoot at the same rate (time between bullets is the same)
-Killing with them both increase light weapon skill.
-They are both silenced.
-K43 does more damage, double if I recall correctly.
-The only better thing about luger is that it reloads faster.
The only reason why I use the luger is when I want to see high accuracy levels with my rifle
