Re: Colt mark IV Government 380
Slide stop lever spring is on the wrong side of the slide stop lever. The little piece that makes contact with the empty mag should be under the spring. Problem is now that it was assembled the wrong way, the spring is probably broken. Remove the slide and were the Slide stop sits there should be a small C shaped spring that has a leg that inserts into the frame and another leg that makes contact with the slide stop lever. You need to insert the slide stop lever with it going under the leg of the spring.
