Installing trigger guard in H&R Topper 88 single shot shotgun. I am not a professional gunsmith, so your mileage may vary, but this is how I _finally_ got it done. 1. The "trigger extension, the trigger, and the trigger guard have to all line up together, and line up with the pin holes in the receiver when the pin is inserted. It is next to impossible to get them to line up, and keep them lined up. Before in inserted the trigger guard into the receiver, I lined up the trigger, trigger extension, and trigger guard holes. Then I inserted two small splinters of wood from either side as shims and pushed them in tight until the holes stayed lined up. I cut the splinters off even with the outside of the trigger guard. After I inserted the trigger guard in the receiver, I got the trigger guard lined up with the pin hole in the receiver, then I hammered the pin through and drove out the wedges. 2. There are two opposing springs that fit in holes in the trigger guard. The rear one goes to the trigger. The front spring goes to the barrel break release. Leave the front spring out to start. Then after you get the trigger guard back in, you can hold the barrel break release up and drop the front of the trigger guard down just enough to insert the spring through from the front of the receiver.
