Simple to use - Wheeler Trigger Pull Scale 309888

This scale works great but there is a couple things to consider. You must use the scale at the same point each time so as to not increase or decrease leverage by moving along the trigger. Pulling at the very end of the trigger will give different results than pulling at the top end. Also guns with large palm swells can interfere with the scale a bit and give varying readings. If you take your time and stay consistent it is as good as any scale twice it’s price.
