no it uses existing spring

Hi Andrew and welcome. No but, I add a wolf extra power spring to all my Glocks for the most reliable feeding from all magazines (towards the bottom under Magazine Springs - 19, 21**, 23, 26-30, 32, 33) : https://www.gunsprings.com/index.cfm?page=items&cID=1&mID=5

Hi Andrew, these work with the existing spring. Stay safe & have a great day!
