I have used TK moon clips and tools for a long time. Forty-five ACP revolvers are my favorite revolvers… I have had quite a few. When I give one of these revolvers away or sell one I include a set of tools and about 25 moon clips - that is why I keep having to buy more TOOL BUNDLEs plus CLIPS.
Loading moon clips for my S&Ws is enjoyable when using the TK tools. Without these tools it would be tough to load the moon clips - I think I’d have to get rid of ALL my S&W .45 ACP revolvers if I did not have the TK tools!
I have used TK’s gunsmithing services to modify cylinders to take TK moon clips on S&W .38/357 K-frames and L-frames. That system works well too...
