Title: What kind of Trigger Pull Measuring system do you use?
Post by: afss on October 18, 2010, 12:40:22 PM

I was asked to advise about the purchase of a Trigger Pull Measuring system.
On the seldom occasions I need to measure it, I use weights. Since I am a little bit "out of the loop", I would like to hear from you, what kind of Trigger Pull Measuring system do you use?  ::---

I use the same method as Jerry. We can also use spring or digital scales.

We use a Imada Model DPS-44 Digital Force Gauge with a Imada wheel-operated test stand Model SH-110.

We used to use dead weights or a spring loaded trigger pull gauge.  However, since I was the only one using the dead weights, they were removed from service.  So...I guess the answer would be "spring loaded trigger pull gauges"?   :-X

We use dead weights or spring trigger pull gauges (like fish weighing scales with out the smell and corrosion).  Sometimes they do double duty here in the Northwest.

Often dead weight will do the job. When the trigger pull is really a big issue (i.e. accidental discharge) , in my opinion one should  consider triggertravel in combination to triggerpull.

Thats why I use dead weights and where neccesary the Trigger Scan.

Hi Erwin,

Exuse my ignorence, what is Trigger Scan?

And another question: Does anybody uses computerized system?
We had one, in the Israeli lab., which showed the force evaluation on the computer screen. But we had to measure the results from it and write them by hand. (Well, we are talkink about the AT model!)

Hi all,

I use an Imada DPS-44 (it now has a new model number) which locks the measurement 'in' for reading. Some of the laboratories that I have worked with has - at my recommendation - started using this devise.

Warm regards,

Jim

Hi all,

Thank you very much for those who took the time to answer.
I looked at the TriggerScan specifications and it seems very sophisticated and "fit" to its purpose, but it is quiet expensive.
I also found out about the use of Force gauge, with data output to a computer, and it is also does the job.
So I guess that the decision will depend on the number of tests there are going to be.
Once again, thank you and I hope others benefited from my inquiry.
