My Shield 40 came with a 7lb, 3oz pull and of course gritty. I installed the complete duty kit and it resulted in a 6lb, 2oz pull. I called Apex and they said to put the original trigger spring in to lighten it a bit more.
I ended up with 4lb, 2oz pull and couldn't be happier. My groups tightened up at 7 yds to about 1 1/2 to 2 inches.

I am looking forward to getting my Shield squared away; I pulled an Apex duty/carry kit out of inventory for personal use and have it waiting on a shield to come in. Can't wait!

Thanks for the tip on using the original trigger spring. I will pass that on to my customers.

If you check out Burwell's site, they show where to do a little polishing that will help some too.

Since you have the Apex Blocker and Sear installed, you may want to finish it off. Also if you put in a stock Glock trigger spring, it will drop the pull about 1/2 pound more. That spring is very similar to the M&P spring. I have it in my Shield 40, which has a 3 pound 10-12 oz. pull. I bought the spring from the Wolf Springs website.
