The circle is a little smaller.
Kevin O'Brien, aka WeaponsMan, passed due to a heart attack. The last two posts on his page are medical updates from family members. Here's his last actual post, a detailed post on gun thefts from FFLs.
If you have the time, his archives are a treasure trove. I will offer one thing he linked to last month. A WWII 16mm movie made by Union Switch and Signal on the manufacturing of 1911s.
