    Picked this up to have some fun with and out of curiosity.
    Cost was under $50.

    Thought I'd try it out on my Revolvers in D/A and S/A and with three 9mm semi-autos.
    I realize my inexperience doing this will skew the results.
    The difference between the high and low was anywhere from 1 oz. to 1 lb. with more on some D/A.

    Gun .22LR - barrel length - S/A avg. - D/A avg.
    Dan Wesson 8" barrel = 2 lbs. 15 oz. (S/A); 9 lbs. 0 oz. (D/A)
    Ruger GP100 5.5" barrel = 3 lbs. 15 oz. (S/A); 10 lbs. 9 oz. (D/A)
    Taurus 990 4" barrel = 4 lbs. 5 oz. (S/A); 11 lbs. 2 oz. (D/A)

    9mm
    CZ Shadow = 2 1 lbs. 15 oz. (S/A); (no D/A only)
    Bersa Thuder Pro XT = 2 lbs. 7 oz. (S/A); 5 lbs. 10 oz. (D/A)
    Bersa TPR9compact = 4 lbs. 12 oz. (S/A); 8 lbs. 14 oz. (D/A)

    Those are some light trigger pulls on S/A. How many times did you do it to get your average?


    On the Dan Wesson, I started out with 10 pulls.
    As I got better at it and the variance between the different pulls was much less, I would do 5 or 6 pulls since the highs and lows were closer.

    In S/A the DW with its avg of 2 lbs. 15 oz. had a high of 3 lbs. and 12 oz. and a low of 2 lbs 3 ozs.: a variance of 1 lb. 9 oz.
    The Taurus 990 only had a difference between the highest and lowest of 6 oz.
    The Ruger GP100 had a variance of 6 oz.

    Firing that CZ one handed must be a workout. :):


    I was thinking of purchasing one of these trigger gauges.
    Thanks for the write up. :yesway:

    It never occurred to me shoot any gun one handed.
    I will have to try that sometime.
    I’ve read about shooting with your weak hand which I’ve never done that either.
    Looks like I have even more fun to deal with in the future.

    When it comes to the trigger gauges I watched videos of a few of them being tested.
    The ones that were recommended to me and with what I saw being tested against each other on online videos gave me the input on which one to get that was moderately priced .

    Most variances will be due to the users technique.

    Try not to pull through the break and hit the stop. Use the same motion every time if possible. As with any tool/gauge technique plays into the results.
    You can and will see diff. from gauge to gauge and user to user.

    Trigger gauges are like car dynos.

    Each is unique and can’t be 100% trusted. Keep the procedure and the machine the same though and you can get meaningful information from delta between changes.

    Thanks guys! :thumbsup:
    I knew when I started out with the D/A pull on the Dan Wesson and got readings from a high of 10 lbs. 5 oz and a low of 7 lbs 13 oz. that my technique was off.
    gmcttr had told me there would be a difference on the reading depending on the technique used and I used them all trying to figure out which gave the most consistent readings.
    I'll do it all again to see if the avg. is close, at least.
    In the vids I watched I saw exactly what you are talking about with "user technique."
    Just another area I have lots to learn, but it is fun!
    The overall results, while not being precise/correct does show what one would think:
    1. Dan Wesson
    2. Ruger GP100
    3. Taurus 990

    It will be interesting to see how my Ruger GP100 .357 Wiley Clapp edition that I am so pleased with will measure up.
    Such a sweet trigger!

    You will see major differences in where you put the bar on the trigger. If you put the bar on the bottom, you have more leverage meaning lower pull weight. If you put it on the top you will have less leverage meaning higher pull weight.
