Ernie Hanson was a Lincoln City, Oregon Police Sergeant for many years I am not sure when he started building holsters. However, I can say he was building them in the middle of the 80's and into the 90's. At some point, I believe in the 90's, he contracted with Lawrence Leather Company in Portland to build his holsters.
That's why you see the stamp on the holster posted. I am not certain where Ernie is now. He certainly is retired and since Lawrence Leather is gone, I believe that there are no more Hanson holsters being made.
His holsters were extraordinarily well built. The design that we are looking at in this conversation was his standard design used mainly for autoloaders. The thumb break design was meant to be taken off upon the draw when the shooter was making the draw vis: the hand made contact with the grip of the firearm and the side of the thumb (around the knuckle) would push off the strap and the draw would be made without the thumb tip doing any pushing. Of course, the strap could pushed with the thumb tip if so desired. The holster was very robust and reliable.
Ernie also made some accessories but his 1001 holster was his main efforts. The holsters that I used for the duty autos that I carried were a SIG 220, then a Smith 645 and finally a Beretta 92. I have one of his catalogs someplace. I will look for it. It could be a bit before I locate it. I will have to wade through alot of stuff that I didn't need but bought anyway.....
