Much better

Replaced stock springs with these and the improvement is very noticeable.

So cal

Sig P-238 spring review

I tested the stock set up after 500 rounds, then cleaned and oiled. Surprisingly the average trigger pull was exactly the same for the dirty and clean gun at 6 lbs 5 oz. I did the polishing and retested 5 lbs 7 oz. then I installed the new springs and the average pull dropped to 5 lbs 5 oz. Great how to video. I Shot the gun after the polish and spring install, it operated flawlessly, trigger felt much smoother. Trigger pulls were done with 8 pulls for each test and then averaged.



Dropped the trigger pull from 6.5lb to 4.5lb


Noticeable improvement

My p238 has new life breathed into it. Easy to install and no regrets on such an affordable simple upgrade!

Extremely Satisfied

First off I want to point out that shipping and getting my order was extremely fast even under the current circumstances. Going to polish and insert the new springs tomorrow in my Sig P238.
