So I picked up my XDS 4.0 9mm today and stripped her down to the bones to replace the springs with the pro trigger kit spring kit. I must say the trigger does feel much crisper now. Total time took about an hour, but I spent about 40 mins trying to figure out why the grip safety spring looked so much different than what I had seen in previous pictures and videos. Haha I then realized Springfield changed spring's shape and fictions recently. I was nervous about taking the xds apart because she is a different breed but all in all glad I did. Can't wait to test her on Saturday!
