Who carry trigger scales in Canada?

Anyone have experience wth the Timney trigger pull gauge? I got one a while ago (via Amazon US I think, as I have an alternate address in the US) and I'm suspicious that it isn't telling the truth. For instance, it tells me that the double-action pull on my S&W 14-3 is nearly 11 lbs., which sounds high.

Remember that in double action, you have overcome the hammer spring tension. 11lbs is less than factory spring pressure.

Try measuring how much it takes to #### the hammer back compared to the double action trigger.

Hmmm.... maybe I've been using the thing incorrectly? I have used it to measure the actual trigger pull,as opposed to the hammer spring weight, which I assume correlates to what I experience when actually firing the gun. I have replaced some hammer springs, but not in my Model 14.
 
No. You are doing it right. Just wanted to point out that due to mechanical leverage, the force needed to overcome the mainspring might be more, or less, than the hammer spring tension weight.
Longer trigger travel would decrease felt double action trigger weight, but take up travel might be to long to be comfortably used in double action. Think of how multiple pulley system works or compound(pulley) bows.

Most people would use a lighter force weight mainspring, but too light would cause light primer hits which is where the softer Federal primers come in.

I'm low tech, I have a pretty good digital scale, and fill a small jug with enough water to make the pull I'm looking for, then suspend the jug using a piece of cord on the trigger. Worked for the last DCRA match we shot.

Been There, Done That :) I've also done some internal polishing and installed trigger & hammer shims on all but my Model 14 (ie 19-4, SP101, GP100) and the triggere actions are very nice, although I don't have access to the same "fairy dust" that the skilled S&W factory smiths had when they made the 14-3! But i sometimes read of revolvers having reliable 8-10 lb. triggers (without backing out strain screws or using really light hammer springs and using Federal primers exclusively) and wonder, "How did they do that?"
