I put in Dons guide rod and #22 spring in my XD40 service. I am having an extremely tough time getting the slide stop lever to release after the gun empties. Most of the time I have to pull the slide back with my hand and then pull the lever down with my opposite thumb. I am wondering if there is anything I can do to make this easier without ripping the skin off my thumb trying to pull it down or do I just need to wait for the spring to losen up because it worked fine before I swapped it. Thanks guys!!
