What is the primary factor that contributes to the amount of force that it takes to pull the trigger? My S&W 41 takes 2 lbs, but my BHP took 7 lbs before removing the magazine disconnect, and now takes 6.5 lbs. Is it because of the stiffness of the hammer spring or is it because of the sear/hammer interface?

Friction on the sear/hammer interface is the primary cause. Whether lacking lube, rough, or to heavy a mainspring, this is the culprit. Other factors are friction of the trigger mechanism itself, and any extra dodads that the trigger moves, like the Series 80 Colt firing pin safety.

Many things contribute to heavier triggers,but others contribute to lighter trigger actions such as reduced spring tensions, the fine polishing of metal to metal contact areas, the angle and reduction of contact drag on the sear to hammer hook engagement, lighter trigger shoes and stirrups ( 1911 ), and the added functions of trigger lockwork. Many triggers also deactivates a passive firing pin safety, but the added pressure on the safety plunger is far less than that of the pressure required to release the hammer from the sear.

I did the 25-cent trigger job on my Ruger semi-automatics to help with the beastly trigger pulls. A little Flitz, some q-tips and elbow grease smoothed them considerably.
I didn't mind with the Rugers because all their parts are twice as thick as everyone else's out of the box. I haven't pickled my Sig or Glock yet. They haven't given me any grief.
