Any suggestions on an accurate trigger pull gauge to use at home, pistols and rifles.
Thanks Scott

Well, first would be the NRA set, but, that's expensive.
Next would be the Lyman digital, and last would be the Timney Trigger tension scale.

The Lyman you can compare to a weight on a digital scale for calibration

I’ve tried a few, digital and spring type, then bought the actual weights. Both the digital and spring scales were off enough to make a difference. If accuracy matters, I’d suggest getting the weights. Plus, the don’t vary or otherwise change over time.

Homemade.  Each ingot is measured at   1 lb. Bullets are 240 gr. The tin with  steel coat  hanger is 750 grs.  Very accurate when adding one 240 gr bullet at a time.

Have measured as low as 9 oz on a free pistol.

Bag-o-bullets.
Since our 230's are not needed any more, make a lift bag-o-bullets.

7000x4/230=122 real hardball bullets that will prove minimum 4# trigger
7000x3.5/230=107 bullets for 3.5#
etc.
do the math

Lyman digital is very accurate.

I have learned that the position you hold the gauge when you reset/calibrate matters. Since most pull gauges you use horizontally, then when you reset it, hold it horizontal. There can be a +/- 3 oz variation depending on position held during reset.

I have a Lyman bought an NRA weight after a rifle didn't make weight.

I like the bullet weight idea.  We just used bullets added to an NRA weight to fine tune a pistol for a Standard pistol match.

Using the coat hanger idea for the trigger hook and ziplok bags with bullets in them you could make a set with 2 2lb bags, a 1lb bag and 0.5lb bag of bullets.  The weight of the hook and bags would be your safety net.  I'd put a rubber hose or some tape over the hook so you don't scratch the trigger.

I made a couple sets out of an old SS shaft. Talk about lasting forever. I did the math, made some guesses and drilled little holes to remove the extra weight. It took about 4hrs but time does not cost much when your old and bored.

When you get real close to the legal weight, even an official NRA set can vary.
My set and Roddy's set are different right at 4#, mine passes a close trigger, Roddy's fails the same trigger.

Build yourself a little cushion on trigger weight range.

Edit-OOps 4# not 3.5

I have a Wheeler digital trigger pull gauge. I also have a RCBS spring type gauge. I really like the Wheeler for checking a lot of different weight triggers. Having said that, I have the all metal weight set, which I always used to check my pistols before matches. Like Bill Blankenship, I always try to keep my trigger weights 1/4 lb. above minimum.

I have both digital and all metal set. It's hard to beat the all metal like this....

Last one on ebay went for like 50 bucks for the whole set.
