Nice job!
I just made a pancake holster for my Ruger Redhawk 45ACP/45Colt. My pattern making skills are not as refined, and while the holster will work, there are changes I have to make to the pattern.
Mainly my leather fails to cover the entire trigger area. It looked good on paper, but failed when the pistol was inserted.
Oh well, live and learn, keep on trying.
