Best upgrade out there
This was a game changer for me. I have weak hands due to a disability. Making this change it has allowed me to shoot even better than I could at my best before the progression of my muscular dystrophy forced me to have to overlap fingers to shoot efficiently. Now I am able to shoot with just the use of my trigger finger easily and accurately. I absolutely swear by this product and I am in the process of transitioning all of my Glocks to these springs. Customer service is top notch also.
