I do not know if anyone has noticed but HKS Speedloader Number 10 will work in a Detective Special/Police Positive Special. HKS says you are suppose to use the DSA speedloader in these weapons. The HKS 10 is suppose to be used for S&W model 10, 15, etc. However, as stated, I have used the 10 in the Colts with no problems. Has anyone else tried this?
