L&R flintlock trouble

I have a L&R late English flintlock. I find it extremely difficult to compress the sear to fire the lock when out of the gun. Seems to work OK in the gun, however with more required trigger pressure than what should be necessary. My hunch is the sear spring is too strong. Hoping some one out there may have a fix.

Might be time to call L&R to get their input and recommendations for a fix.

Thanks Grenadier, I'll call first thing Monday.

Ya Zonie, that's kinda what I was thinkin, lightening the spring, thanks.

L&R was very responsive when I had issues with their locks. Less than one week turnaround after mailed.

For a test remove the mainspring and sear spring(optional) then set the hammer to full cock. Hold the lock nose down and slowly press the sear. The hammer should just drop of its own weight. If it moves backwards(upwards if the lock is nose down.) before dropping, the sear nose or notch angle is off. That wrong angle forces the sear nose to push the hammer back against the mainspring before releasing. Lightening the sear spring will help but you still have to overcome the mainspring tension.
Another test would be to remove the sear spring and VERY CAREFULLY bring the lock to full cock and snap the lock with the frizzen closed, of course, to see what sear pressure without the spring is required to release the sear.
Or you could just send it back, pay them, and never learn anything.

I filed the sear spring lightly, and polished the tumbler notches and sear nose, it really made a big difference, all is good now.

Make sure the tip end of the spring is not binding against the sear.
