Same here. I play a lot of recon too and have more kills with my M1911A1 than any other weapon in the game. It's the only weapon I have a gold star with. I have a decent amount of kills with the rifles but definitely do a lot of spotting. Love that spotting scope gadget.
Also agree with the C4 thing. Although when I first starting playing I didn't always get far away enough before detonating and had a lot of suicides. LoL
