Okay, so I bought the following in order to make a pull gauge;
1 - 1/4" x 36" zinc plated rod ($3.49)
1 - 2" piece of 1/4" i.d. Tubing (free)
1 - Plastic milk jug (left over from water for snake)
I bent the rod in a manner to achieve a shape of a question mark or "S" with a small hook at lower end for the weight to hang. Not to hard, completed in about an hour.
Got the guns out and started to the process of measuring the trigger pulls. For this test I would point the gun straight up and hang the gauge on the trigger then hang the milk jug on the hook. I would then add water till trigger breaks and then start fine tuning where the break actually occurs. Works very well aside from quickly finding out the food scale I have won't weigh over 38 oz. or so.
anyway, I now have a system of measuring my trigger pull weights but all I need is a $50.00 scale. Huh? Maybe i should have bought a digital pull gauge? Naaa. I'll just pour the water into a smaller container and sum up the total. .
Well in this process I found out my GP100 has a SA pull of ~4.25lbs and a DA pull of ~8.1 lbs. The SA pull is heavier than I expected. Kind of surprised. Would have thought it to be in the 3-4# range??? So I also found out my CZ SP01 has a SA pull of ~4.72# and DA pull of ~8 #. The CZ feels heavier than the GP, however the GP is a lot smoother though. Exactly what Iowegan said, BTW. Looks like I'm going to have to do some polishing. I still need to replace the trigger return spring of my GP which would help as well. The CZs SA pull would be significantly better by replacing the stock hammer with CZs competition hammer, and rid of any camming. In the near future perhaps.
I also found out the break of the trigger, whether in SA or DA is affected by the angle at which you hold the gun in relation to the gauge. If I hold the guns barrel perpendicular to the ground, i.e. straight up or parallel to the gauge the break is at a heavier weight. Whereas if I hold the barrel slightly tilted forward, thereby causing the gauge to rest towards the tip of the trigger, the subsequent pull is lighter. That would be expected due to the physics of levers. Anyway that very well could be some of the discrepancy some people get between pulls when measuring. This whole bit of a project was fun and cheap but definitely a bit more of a hassle than having a pull and read device. To simplify it, Instead of using water, I would like to devise a way to use some sort of weights. But 8-10# of washers would be ridiculous. Might be able to use free weights.
Oh sorry no pics, my camera is on vacation. Will up date when I can.
