I have a very old fanny pack holster that I purchased in the 80's. Can't recall if it's by Desantis or Galco (both made similar items). It was designed for a large semi-auto and I regularly carried a cocked-and-locked Browning Hi-Power within. Hey, it was the 80's! A fanny pack wasn't really out of place at the time. Probably I still have it around somewhere in a box.

Apropos of nothing around that same time I bought a Galco Miami Classic should rig for my BHP as well. Seems like it cost the princely sum or $100 or so, a small fortune to a college kid in the 80's. I still have that as well but I haven't carried the Browning a long time, having transitioned to more modern designs by HK.

Circling back to lumbar packs I still regard the True North Gear SERAC SAR as the best day pack out there even though it hasn't been made in at least five years.
