Quick Answer
For a Sig P320 with a Streamlight TLR-7, choose a holster molded specifically for that light and model, with adjustable retention and a secure belt or clip system.
Why Light Fit Matters More Than the Gun
A light compatible holster locks onto the weapon light, not the trigger guard. That means the holster must be molded for your exact light model and the P320 variant you carry. A holster made for a different light can be loose, wobble, or fail to retain the gun safely.
Check the holster description for the specific P320 model (Compact, Carry, X-Carry) and the light (TLR-7, TLR-7A, TLR-7X). If it lists only a generic 'P320', confirm compatibility before buying.
Appendix Carry and Spare Magazine Access
If you carry appendix, a holster with a built-in magazine carrier keeps your reload close without an extra pouch on your belt. This setup works well for everyday carry but adds bulk, so it's not for everyone.
Kydex thickness affects durability and comfort. Thicker material holds its shape longer but can feel more rigid against your body. Thinner material is lighter but may flex more under pressure.
Decision Rules for Choosing a Light Compatible Holster
- Confirm the exact P320 model: Match the holster to your P320 variant (Compact, Carry, X-Carry). A holster for a different size may not seat properly. Double-check the model in the product title before ordering.
- Match the light model: Pick a holster molded for your specific light (TLR-7, TLR-7A, or TLR-7X). The holster retains on the light, so a mismatch means poor retention. If your light isn't listed, contact the maker before buying.
- Decide on appendix with or without a mag carrier: If you want a spare mag at hand, choose a Side By Side style holster. If you prefer a slimmer profile, get a standard holster and carry a separate mag pouch. Consider your daily clothing and comfort before choosing.
- Check retention and adjustability: Look for adjustable retention screws so you can fine-tune how firmly the holster holds the gun. Kydex should click securely around the light. Test the draw and reholster at home before carrying.
