I’ve been an Sig armorer since the early 90’s. This is an excellent spring kit. I bought an E2 grip upgrade for my older P220. The kit didn’t come with the mainspring. The factory mainspring is 21 pounds. This kit gives you a 17 & 19 pound spring. I installed the 17 and it significantly smoothed the trigger pull. I’m planning on buying another spring kit to upgrade my older P226.

I am a new customer to Top Gun Supply. Simply put the service I received was excellent. From order to follow up with super fast delivery. The spring set was perfect and reduced both the SA and DA trigger pull on my Sig P226 MK25. The competition sear spring reduced the load on sear engagement (very nice) Thanks Brad and Rachel for the excellent service!
