More sugguestion for OP
Galco offers holsters they call somthing like " Flatside" , to which the pice of ltather closest to body is flat, and the outer leather is molded for the entier width of the gun.
In general , an open bottom pancake will conform better than a closed bottom.
The style of belt slide with fore & aft slots will be more flexible than a full length pancake. More of bbl/ slide will be exposed, decide your trade offs. Also more concealable. While there are fans of pancakes with or without a thumbstrap, on a belt slide , the gun is more suseptable to being pushed out of the holster by having muzzle end contact a chair arm, or whatever. I prefer thumbreaks anyway, so no issue for me. For guns that either have modern high tech indestructable finish, or already have *character*, I'm not too bothered by having the extra exposure.
And yes , the box of holsters is inescapable.
In my formative carrying years, a semi-local Police Supply store had a very deep stock. If I were interested in a particular style of holster, Vern could produce a half dozen different models/ brands to test fit. Also I haunted the used leather box at every oportunity, and would buy holster that were different, just to try to see if I might like them either generally, or for specialized use. But alas, Vern closed down decades ago, and used leather is now rare.
Not sure what position OP is placing his holster, but will probably have fewer issues with conforming if placed at 4:00- 4:30 position vs 3:00 . ( Right handed references for behind the hips, vs point of the hip.
All else fails , consider an Avenger style holster. Those are tunnel loop center of holster, AND a trailing loop to pull closer into body/ keep in place with less shifting.
