I have also had trouble finding a holster that fits it correctly, I'm sure the kydex rigs that Sigarms sells from it's website will fit it but I really don't care for them, I'm just old school I guess, I like leather. I got a Tagua for it but it really doesn't fit it well. I have a nice rig for my Kimber Ultra, that I got from Ryan Grizzle, and it is perfect for the weapon and for me. Ryan says up front his 1911 rigs will not fit the Sig and he doesn't have a form to build one.
I like how the stock grips look but I find I have to have something larger (Hogue wrap-arounds) to make it better fill my hand. Otherwise it is a nice shooting, good looking. dependable 1911. Any help on a good leather rig would be appreciated.
