I bought a new 4" blue M25-5 in August 1980. I round butted it and carried it on duty for about a year. A while later, I sold it to my patrol LT. In 2007, I bought it back from him. He passed about 1 1/2 years later.
It won't be sold again, not while I'm living anyway.
I think it was worth the $350 I gave the LT.
