cpa5oh Posted December 3, 2013 Share Posted December 3, 2013 I would like to get a trigger pull gauge given I do work on my guns from time to time. On the cheap end, there are trigger pull gauges like this one - http://www.midsouthshooterssupply.com/item.asp?sku=000449450&clicks=BOX2&clitem=000449450 A little more expensive is this one - http://www.midsouthshooterssupply.com/item.asp?sku=000157832248&clicks=BOX1&clitem=000157832248 And most expensive is something like this - http://www.brownells.com/gunsmith-tools-supplies/measuring-tools/trigger-pull-gauges-weights/nra-official-universal-trigger-weight-system-prod9710.aspx Biggest thing I want is repeatability - I get real frustrated when I try something and I get results that are all over the place. Not as concerned about price - but the NRA one seems to me like it might not measure as precisely (I imagine those weight you hang don't come in 1 oz increments - not really sure how small the smallest increments are.) Thanks! Link to comment Share on other sites More sharing options...
Steve RA Posted December 3, 2013 Share Posted December 3, 2013 I've got one of Lyman's digitals and it works very well. You can test one by picking up something of a known weight and see if it comes up with the same answer each time. Actually, to check the tracking, just pick up something numerous times and see if it has the same answer each time. Link to comment Share on other sites More sharing options...
Guest Posted December 3, 2013 Share Posted December 3, 2013 Probably the most accurate are the dead weights, but IMHO they are a bit of a PIA to use on the bench when working on your gun as you have to have the trigger parallel to gravity and there is some technique in using one correctly. I have an old RCBS spring scale like you posted and it works well. I have access to a metrology lab and asked them to check it for me and found it read 1 oz high from 16 - 32 oz, and was dead on at 64 oz. That is close enough for my purposes.

ltdmstr Posted December 3, 2013 Share Posted December 3, 2013 (edited) Absolute best for accuracy and repeatability is the old style steel "official" NRA weight set. Brownells still sells them. Only downside is the lightest weight in the set is 2 lb. So if you do lighter triggers, you have to make up your own 1 lb weight to use as a base.

cpa5oh Posted December 3, 2013 Author Share Posted December 3, 2013 I don't understand that last post - the lightest weight is 2 lbs...in the picture I see a 1/4 lb weight and a 1/2 lb weight? Link to comment Share on other sites More sharing options...
ltdmstr Posted December 3, 2013 Share Posted December 3, 2013 The base has a threaded hole for the hanger that hooks on the trigger. The set comes with a 2 lb base and the other weights have the slots so you can stack them on top of the base. The stock 2 lb. base is the big black weight that's behind behind the silver one with the hanger mounted on it. The silver one is the 1 lb base that I made up. Basically, just cut a piece of bar stock that was the same o.d., drilled and tapped for the hanger, then removed material from the other end until it was exactly 1 lb.

Jediwarrior Posted December 3, 2013 Share Posted December 3, 2013 Have you checked out the Brownells Recording trigger pull gauge for $110? http://www.brownells.com/gunsmith-tools-supplies/measuring-tools/trigger-pull-gauges-weights/recording-trigger-pull-gauge-prod4985.aspx I believe in spring type recording gauges as they as quick and easy to use. No need to guess which weights to put on and off. The cheaper spring type gauge such as this one is what I have in the range bag: https://www.dillonprecision.com/#/content/p/9/pid/24585/catid/30/The_Tru_Weight_Trigger_Tension_Scale Tru-Weight Trigger Tension Scale sells for $26.95. RCBS and Timney sells exactly the same for a little more. Link to comment Share on other sites More sharing options...
cpa5oh Posted December 3, 2013 Author Share Posted December 3, 2013 Thank you guys for the replies! Ended up ordering a spring type unit like the last one in the post above. I got spooked from the posts about the units with the hanging weights and I'm (hopefully) gonna be keeping it simple. The post that said his spring unit was accurate to within an ounce sold me on the spring unit. I'll be happy with accuracy to 1/4 lb. I just did a bunch of work on a tanfoglio stock 2 and u wanna see if I'm anywhere near the 5 lb da pull smiths say they're getting. My guess is 7, but I really have no idea until I measure it...

ltdmstr Posted December 3, 2013 Share Posted December 3, 2013 Spring gauge should be fine for your application. If you were doing something like a bullseye gun for competition, I would recommend static weights. Link to comment Share on other sites More sharing options...
