That sucks!
I had a friend that was a dealer, his name was Squeak and he called me Toe Doc (there is a story I'll share some time), who died of diabetic complications after a surgery; I lost my gunsmith as he was working on a revolver for me and getting ready to start a conversion on my open gun (.45acp to 9mm major), and my favorite FFL/Eye Doc/very good friend is struggling with age, health, and the sudden loss of his life. Then today I came across the obituary for another friend (SASS shooter and gunsmith).
I need to find younger friends!
