Does anyone actually use a spring gauge?

Recommended Posts

saw a video online of a guy that actually weighs his recoil springs and trimmed down the new spring till he gets the desired weight. 
 

wow

 

way to much work. Do people actually do this?

Try it and see how much springs vary from what's written on the packaging...

 

But it really doesn't matter much unless you're looking for some crazy-magic combo.

I make the spring tester sold by brownells and dillon.  it is not so much about a magic combo unless you are creating loads for a specific function.  too light a spring will produce frame battering and too heavy will not let the pistol function correctly.  well used springs need to be checked to verify they are not weakened.  Our Bianchi guns have 7 lb recoil springs and 14 lb mainsprings in order to function.

 

In a nutshell if you use factory loads in a factory gun it might not be that important.  If you are creating a load to shoot 1/2"  groups at 50yds. it might be.

I can see bullseye shooters wanting to tune a load for that purpose. USPSA shooting major tho I feel is overkill.

 

if you have a 10 pound spring, how many rounds until that 10 pound spring goes down to a 9 or 8 pound spring?

I purchased a spring tester from Brownells  and use it all the time it really makes a difference in how your gun functions.   Try one and see for your self.

I've had a spring tester Brownells that I've used for at least 7 years now. I dig it out at the beginning of the season to check and replace springs if necessary.

 

I have the older "fish-scale" type tester. I do like the updated digital version a bit better. I'll get one during the black Friday sales.

Yes.  Just started using one the past year after I noticed some questionable results when tuning a couple of open guns.

Was REALLY surprised by how far off some springs are.  Worst was probably a new spring marked 9 lbs that 

was actually 6.5 lbs.

This!  I use a spring gauge regularly.  I've added additional marks on my gauge for various pistols to check for coil bind at full recoil.  I don't trim spring length to tune for weight, but I do have to trim springs for some pistols to prevent coil bind.

I shoot mainly 1911 in 45 acp,  I shoot at  a range twice a week for practice.  My range guns as I call them are loaded with light loads as I don't like beating the crap out them.  I probanly shoot 200-250 rds a week.  I put lighter main springs and recoil springs so these guns function and it does take alittle work.  I made a spring tester a and you would be surprised what a difference it makes as I do like using different loads and bullets.  My self defense guns are pretty much std. spring tensions.

I just got one also from brownells. They are actually very useful. I also switch out slings prematurely in my open gun to make sure I don’t crack anything. Because I do this, I think it’s imperative to make sure the spring I’m putting in is Correct. Who’s to say the guy at wolf didn’t make a mistake and put a 7 pound spring into the 9pound package?  Mistakes happen all the time and if a $25 dollar tool will help protect my gun, then I’m all for it. A slide and barrel done right is easy $850 bucks. Springs and gauge are cheap!  Don’t knock until you try it!

I'm getting one from my daughter for Christmas.  My biggest problem is that I have about a dozen Wolff springs in a drawer and I don't know what the hell they are.

I use a spring tester for my recoil spring in my open gun. It is really surprising how far off the same brand of springs can be. I use a 6lbs in my open gun. I have measure some other 6lbs springs closer to 7lbs and even one close to 5lbs. So once you find the spring you like, you can test it and then cut down springs until you always achieve that goal weight.

I also built one myself.  It might not be 100% accurate but it gives me a comparisson between different springs I have in my parts box.

I can use it for hammer and recoil springs.  I measured several springs from the same manufacturer where the spring that should be lighter in fact was heavier.

Why do shooters worry about a  1/2 ounce difference in trigger weight but are not interested in spring weight.

It is like mounting a crank in a racing engine without measauring the clearance because the factory said that it was ok.
