Sig Sauer P365 XMACRO TLR7-sub (1913s) IWB Holster

02/23/26 - Update: Left hand IWB model is now available in the print profiles. 

This model is a printable version of a thermoform-style holster, purpose-built for makers who want to print, fit, and carry. Designed for the Sig Sauer P365 XMACRO with the Streamlight TLR-7sub installed.

Features

• IWB design with full-height sweat guard.
• FOMI & Tri RCS hole patterns for wide compatibility with most IWB belt attachments.
• Mounting holes for the ModWing LB concealment claw (recommended) double as adjustable retention points. Includes a third hole behind the claw head for added stability - replace the short factory screw & nut with the specified size below.
• Built-in concealment geometry: raised offset behind belt attachment helps pull the holster tighter to the body, even without a claw.

Material & Printing Tips

• Recommended material: PLA Basic is fine, PETG is recommended. For users expecting excesive heat, ABS or PET-CF is recommended.
• Supports: Required and can be stubborn dependant upon print orientation and support settings. Clean carefully to avoid over flexing and snapping the sight channel - applicable for more brittle mateirals. A needlenose pliers is quite handy here.
