Improved my trigger pull tremendously

Great kit at a great price. Made such a difference in the effort needed to squeeze the trigger. My wife can now fire the weapon without hand fatigue, before her limit was 3 times. Also she doesn’t complain about being able to hold on target when firing.
One improvement would be a install tool for the trigger spring. I used a 3/8″ piece of ink tube out of a bic pen to hold the spring in position for the pin to push it out. It worked great but to have one included like another kit does would be nice since it is all but necessary.

The Springs arrived in a timely manner and worked as advertised. Trigger is much improved.

Only change I would make is the zebra code takes you to a different gun video. I’d prefer to have a quick link to the related installation instructions. Product is great and a noticeable difference as soon as reassembled.

This kit was delivered promptly and was as advertised. Installation was not difficult.

Your trigger return spring does not fit well in my SW9VE. Its conical shape makes the forward end (fat end) too wide to fit easily into the notch that receives the pin. It did eventually get reassembled and worked.
