Gun, grappling hook
For the initial gun sound I actually used a real gun pulled out of a plastic holster fairly quickly. Then I added a small air blast created by an air compressor. Then for the rope flying through the air I used a short string and spun it quickly and then pitched it up, and finally for the impact I used two bricks for a quick debris impact and the sound of a metal shovel impact. Worked out nicely.
