I have a Colt Huntsman that I've owned for a few years. The slide has been pretty sticky when sliding it back. I've never fired it, and it is in very clean condition. It looks perfect to me. After procrastinating disassembling it for a long time to clean the slide and frame of the stickiness, I finally did it. I watched a Youtube video to make sure that I was doing it correctly, but I ended up with a couple of problems. The button on top of the slide fell out. I have not been able to put it back. It seems to only be able to go back from the bottom of the slide. However, the spring and the spring guide are blocking it from entering the hole. The second problem I have is getting the slide back onto the frame. In the video that I watched, the slide is supposed to go back easily, but for some reason I can't get it back. If someone who reads this is able to help me with my Huntsman, please give me a shout.
