Stronger Trigger Reset/Return Spring?

[Alllen Bundy]

As I was looking for Sig P365 parts I discovered a company offering a stronger trigger reset/return spring. I use my P365 and P365XL strictly for carry and not for competition.

The trigger on my P365 and P365 XL requires between 3.5 and 4.0 lbs of pull force at the tip of the trigger and about 7 to 8 lbs of pull force in the middle of the trigger where my large finger pulls. I measured this variation using the weakest combination of springs and the strongest combination of stock Sig springs that I had on hand. I don't have any issue with the trigger pull requirement as it is and probably wouldn't mind if it required a slightly higher amount of force.

Correct me if I'm wrong, but wouldn't a stronger trigger reset/return spring aid in the trigger reset?

If the reset/return spring is stronger, would that make "the wall" feel less distinct?

Has anyone tried using a stronger trigger reset/return spring and if so, what were the results?

I haven’t gone up in weight with a trigger return spring on an auto, only lighter. This did reduce the pull weight, with only a minimal slowing affect on trigger return speed or reset feel (to me, anyway.)

It stands to reason that a heavier spring would push the trigger mechanism back with additional force, therefore increasing the trigger return speed and reset feel while increasing trigger pull weight to overcome the stronger spring.

I did have to add a stock-weight trigger return spring when I got my used 4.2” SP-101 .327 Federal home. It looked like the original owner clipped a coil or two from the reset spring to “improve” the stock trigger. The pull was lighter, but it caused incomplete trigger return and a balky reset.

I bought a spring kit with multiple weights, and found that anything less than an OEM spring wasn’t reliable. With a bit of polishing in a few spots the OEM spring made the trigger a tad heavier than when it arrived, but it was now reliable.

Stay safe.

The stronger trigger reset/return spring is only $5.95 from Sig Guy. I think I'll try one and find out what it feels like. I can replace one in less than a minute on a P365, so why not?

I just tried the ISMI 10% stronger trigger return/reset spring in my P365XL. I measured a 7% increase in the force (over the Sig trigger return/reset spring) required to pull the trigger and release the sear. In a direct A-B comparison I can feel a slight increase in the force required to pull the trigger to the wall. But I can't really feel much of a difference in the force required to pull the trigger beyond the wall and release the sear.

I think I will keep it. It may help to a small extent to help reset the trigger faster.

I understand the reasons why people modify their triggers for competition shooting. But what about reducing the amount of take up on the trigger on a carry gun used for self defense? Are there any pitfalls?

I'm not trying to convince you one way or the other, I'm just answering your question.

From Ernest Langdon - "it's the distance that the trigger moves that keep us out of trouble, not the weight of the trigger."

Having taken a class from Ernest and heard him say that in person, I'd have to agree with the reasoning and warning.

Just for clarity, he was referring to the distance the trigger travels prior to contact with the sear (pre-travel) and also how far it moves before the sear is released

Thanks for posting this Link.
Thats the reason my carry autos are DAO with hammers. (sig p250, etc.)
Being able to thumb the hammer during re-holstering while training is way better than a striker fired gun.
