The holster I referred to in my earlier post is a de santis. I believe it was called a Scorpion. it is not shown in the current De Santis catalog. I have had it since 1994.
I use it when I am carrying my Springfield factory comp.
My normal carry is a Roy's Original Pancake Holster. When I purchased it Pappy, as we called Roy had me apply a heavy (almost a whole can) coat of saddle soap to the holster. I then inserted my 1911 government model into the holster and let it set for two weeks.
The holster molded to my pistol and the pistol fits like it was factory molded. On non parkerized finishes I would recommend wrapping the pistol in Teflon tape for the two weeks.
I wear the pancake because it does not print and the thumb break is second nature to me.
