What is a 'good' trigger pull?

[TennBill2]

I pose the question with my 'Borchardt' project in mind. I'm of the opinion the Luger and Borchardt fire essentially the same. I had been working on getting the right firing pin tension. I discovered I had an abominable trigger pull.......as in pull as hard as I could! Looking at the blueprint drawings(Luger) of the sear bar, I increased the angle a tiny bit. Voila', I now had a 'hair trigger'. "That's not good", said I. Back to the grinding wheel! With a 'safe' file, I took a thou, or so, deepening the depth of the striker's retaining notch, but not changing the angle. Wow! as luck would have it, I wound up with what I consider a perfect trigger, firm but not heavy. How does one measure trigger pull? I suspect there must be 'tried and true' methods for tuning a standard Luger pull, what ever that might be. My two 'off the shelf' Lugers handle fine. But I guess replacing a striker, or sear bar may upset the balance of things. Bill
