Is "push-off" really such a big deal?

[05CarbonDRZ]

Bobby,If You take the Triggers out of the Guns with push off and send them to me I would be happy to stone them for You.I have done it numerous times in the past.Shoot me a E-Mail if You are interested.

Thanks Alex. I've already taken them to my local Smith.
f.t.

p.s. The trip to the shop cost me $1,000! They had a NIB 6" 16-4 that I couldn't pass up.

 

[Doubless]

If that 16-4 is truly NIB, the money you spent was not a cost, it was an investment. Those are rare anyway, and to find a true NIB even more so!

In both bobsled racing and handguns, push - off is important.
Need to get it right!

The fact of which I am keenly aware.

A quick sharing here on a method to restore the proper angle and edge on a SA trigger sear. I bought this Power Custom Stoning jig knowing I wanted to learn to do some trigger work and here is a case where it worked well. The jig is adjustable, the wheel to the right can be moved in incremental clicks up or down from 'standard' to increase or decrease SA release. I liked the fact of offering repeat settings for all my triggers.

My trigger had a very poor edge where it appeared someone put a slight bevel on it and also had a slight burr edge roll to it so it did a poor job of sitting properly into the SA hammer sear notch, push off was quite easy.

Just to share the concept here is the jig and set up I used.....the trigger is lightly clamped to the jig on the left when this is done, a 6in Arkansas stone is recommended, I ink the surface to be done and make light passes with an oiled stone and watch for the edge to form.

I would also like to sincerely thank one of forum members who is an armorer for his assistance and willingness to share a lot of valuable and helpful information with me. Thanks Carter

What is push off?

 

[H Richard]

Push off is the inability of the hammer to stay in the sear notch when applying a "light" forward pressure to the hammer when in the single action cocked position. It makes the single action a "hair trigger".

 

[Boogsawaste]

How hard is "light" pressure? I've checked with thumbs (which I don't like to do since it's not measurable and one can push hard enough to create this on pretty much any gun), I've set the gun pointing up on its hammer using nothing more than the guns weight, and lastly I've placed a 5lb weight on the hammer with the gun pointed down.

Just curious to everyone's methods.

Edit, checked my weight and it's 10lbs, not 5 like I thought.

I have checked my 625JM and my 686-3 after doing any trigger work or springs and have applied some firm pressure to check for push off, I would imagine this may exceed 10+ lbs or more.
Just recently the used gun purchase I made tripped off pretty easy in my mind and surprised me as it is the first time I experienced push off. Using a Lyman digital trigger gage I measured it would 'pust off' at about 5lbs of pressure.

I think perhaps from this point forward maybe the correct way to evaluate is to use the gage and take it up to 10-12lbs to check for push off and stop there?
I am sure there must be a set standard to check for push off??

push off "standard"

This is from the S&W Armorer's manual, the closest thing to a "set standard" I can find....straight from the horse's mouth, so to speak:

After confirming weapon is empty...."Cock gun in single-action position. Place thumb on back of hammer with finger off trigger. With moderate pressure (not exceeding 6lbs) push the hammer forward. The hammer must not fall."

If you're having a hard time "quantifying" what "6 pounds" of pressure is, hook your trigger pull gauge on rear of the hammer and pull forward until you reach the 5-6 pound mark on the scale. Remember...... do all these tests on the internals with the sideplate on.

 

[Boogsawaste]

Thanks. Guess I should switch to 5lbs instead of the 10 I have. I'll go push on a scale and see what 6lbs feels like. I'm betting it's not much at all.

 

[Nevada Ed]

Well if you have big FAT fingers like me...........

they take up 3 lbs of trigger pressure, just getting into that teeny weeny trigger hole !!

I never have beans before a shoot !!

I like the beaches in SC. SC may be Gods' county, but strikes me as a place not to bring your carry gun. At least I can take it in to my condo. That said, I discovered push-off after a Bullseye match when my Python hammer failed to drop while firing single action. Instead, it fell slowly as I allowed the trigger to return forward. I found that the hammer also pushed off, so I took it to the gunsmith that worked on the action 17 years back. I showed him the push-off and he cracked "don't do that". He fixed it; I didn't ask what he did, but the trigger now feels heavier then the previous 2 1/2 #.
