More images.
Here is one with the respective sidearms in place, almost. The leathersmith did not have a S&W Model 22-4, (4”, N frame, fixed sights) so he used a Model 625 as his model. The S&W Model 625 is an adjustable sighted N frame and that makes a difference.
The welt stack is cut so as to lock the handgun in place by pressing the top strap of the frame into the folded portion of the holster. There is sufficient difference between the target model (adjustable sights) and belt model (fixed sights) that the interface is lost.
This image is my commissioned holster with a 4”, S&W Model 25-2 in place. I held it like this for 5 minutes before taking the image. My arm got tired of holding it.
Here is an image of the antique Sessums holster with a Colt Civilian Model 1911, also after 5 minutes.
Both held in place and probably would until my hand gave out.
The S&W Model 22-4 dropped from the holster after 2-3 seconds! However, when the holster is on my belt, the revolver stays in place.
