ALPHA-X Holster for JEM Square Trigger Guard

[Vizorn]

Hey guys -

 

Does anyone know if there is a DAA Alpha-X holster insert that will fit the JEM Guns 1911 square trigger guard (perhaps the Caspian Square Trigger Guard insert)?  I'm considering my options for a 1911 build and I'd prefer the stability of the square trigger guard in that holster as the 1911 round trigger guard tends to wobble a bit without the muzzle support attachment.

 

 

Thanks!
