The water and jug method will work, but it’s awfully tedious. For those who only own 1 or 2 guns, aren’t in need of exact trigger pull weights, and have no intentions of getting any more in the future, this method may be worth using. However, a wheeler trigger gauge can be purchased on Amazon for $20. If it’s important enough to know the trigger pull weight of a gun, that’s a nominal one time fee.
Exact trigger pull weight is more important for rifles and handguns than it is for shotguns, but a good trigger scale can be useful to weigh things other other than just the trigger pull. The weight of the entire gun for example. I even use mine to weigh my backpacking gear.
