My son-in-law is on the Minneapolis SWAT team. He gave me a tactical vest that is absolutely the best photo vest I have ever seen. It is available from law enforcement supply houses.

My Pentax digital spot meter drops into one of the pouches just like it was designed for it. It has large slotted pockets inside that handle camera back covers and fresnel lenses beautifully. You can check it out here:

They carry a size small but I am certain it is a men's small.

Glock pistol supplied seperately.
