I wasn’t happy with the composite holster for my Ruger SR22. I finally found a leather holster that wasn’t exactly made for it, but should fit it fine. Well, it was too tight, to the point where re-holstering the weapon would almost rack the slide back - that’s too tight.
When I first got into this sport I read a post about the “drawer full of holsters” that comes along with it. I seemed to be getting a good start on that prophecy. Then I saw an add on Amazon.
Foot Matters makes a Professional Grade “Shoe Stretch” product is said to work on all manner of leather, reptile skin and other such material. So I ordered a small bottle for my holster. It worked!
I rapped the gun in a thick plastic bag, sprayed the holster inside and out to near saturation, and then jammed the bagged pistol into the holster and twisted it around a bunch. (Be sure to remove the magazine and clear the chamber first!) An hour or so later it was better, but not yet right so I did another application, as the label recommended. Now that holster fits my SR22 like it should.
