Diagnose common fit problems with the Garage Sale Low Pro holster for Sig P320, M17, M18, and Carry models, and learn when to adjust or choose another option.
Quick answer
The Garage Sale Low Pro for Sig P320 usually fits best when your pistol matches the listed models and you carry inside the waistband with a sturdy belt. If you feel excessive tightness, a loose draw, or discomfort, check the retention points and the modwing claw first, then confirm your model and accessories.
Why the Low Pro can feel different across P320 models
The Low Pro is molded to fit a range of P320 variants, including Full, M17, M18, Compact, Carry, and X-Carry. That broad compatibility means the same holster may feel slightly different depending on your exact slide length and grip module. A Full-size or X-Carry will fill more of the holster body than a Compact, which can affect how the retention points engage. If you have added a compensator, the fit can change further, which is why the manufacturer asks to be informed about comps when ordering.
The trade-off of a concealment-focused design
The Low Pro is built to be the most concealable inside-the-waistband holster in the lineup. It uses a modwing claw that presses against your belt to pull the grip closer to your body, and it accommodates red dots, suppressor-height sights, and threaded barrels. That focus on concealment can make the holster feel tight or awkward at first, especially if you are used to a looser outside-the-waistband rig. The same features that reduce imprint can also create pressure points or make the draw feel stiff until you adjust the setup.
Diagnose your Low Pro fit issue
- Symptom: The holster feels too tight or the draw is difficult: Likely cause: The two retention points may be engaging more than necessary for your specific P320 variant, or the holster is still new and stiff. Corrective action: Ensure the pistol is fully seated, then practice drawing and reholstering several times to wear in the holster. If tightness persists, check with the manufacturer about retention adjustment; do not modify the holster yourself. If the holster remains too tight after a few dozen draw cycles, consider a different holster designed for your exact model.
- Symptom: The pistol feels loose or shifts in the holster: Likely cause: Your P320 model may be smaller than the holster's maximum fit, or an added compensator is changing the lockup point. Corrective action: Confirm your model is listed as compatible (Full, M17, M18, Compact, Carry, X-Carry). If you have a comp, contact the manufacturer before ordering to verify fit. If the looseness is excessive, do not carry until retention is resolved. A holster that does not hold the pistol securely should not be used for carry; choose a model specific to your setup.
- Symptom: Discomfort or pressure points when carrying: Likely cause: The modwing claw is pressing too hard against your belt or body, or the holster position is not ideal for your build. Corrective action: Try adjusting the holster's cant or ride height if the mounting allows, and experiment with belt tension. A stiffer belt can sometimes reduce claw pressure by keeping the holster stable. If discomfort continues after adjustments, the Low Pro may not suit your body type; consider a different carry position or holster design.
- Symptom: The holster does not accommodate your red dot or sights: Likely cause: The Low Pro is made to accommodate red dots, suppressor-height sights, and threaded barrels, but extremely large optics or unusual sight setups may still interfere. Corrective action: Verify that your optic and sights are within common dimensions. If they are oversized, the holster may not work. Check compatibility with your specific optic before ordering; if unsure, ask the manufacturer.
