Personally, I do not use CCI primers! But, I want my guns to fire all ammunition reliably. In addition, I discovered years ago that a firm trigger actually aids in accuracy and a light trigger pull messes me up. You may not have the same problem. :-)

Given the gun is in full spec otherwise, light strikes are virtually always mainspring issues. If it has a ribbed aftermarket spring, the strain screw will sometimes round and engage deeper in the open side of the V causing a lighter strike.

As Toolguy noted, Smith springs are excellent and seldom cause issues unless altered. I do not use aftermarket springs in any of my guns, except those few that come from the factory with ribbed springs, which I think they did not make. (Although I don't know that for a fact, but they look like Wolfe springs to me)
