I have always used leather, so know no other. Carried in a leather shoulde holster for 30 years. Now I use a Gould slide holster, leather, works great for me.
Now that I think about it, have never used anything other than a Gould, bought my first one at the factory,,
Well, I just thought about it. I bought my second holster from Gould because they weren’t in business when I bought my first. That one I bought from a custom holders maker right down in Mexico, it was easier back them
And I do not agree with Skippy that leather wears a gun faster.. he has his opinion, I have mine,
