Checkout our Holster Highlight: The Level 2 Duty Holster for the Sig Sauer P365 X-Macro with the Streamlight TLR-7

From Sig:

With an innovative new magazine design the P365-XMACRO COMP packs a full-size 17+1 round capacity into the thin, iconic profile of the P365. The P365-XMACRO is also more shootable, with an integrated compensator that reduces muzzle flip and makes follow-up shots faster and more accurate. And with its slim, 1” wide design the P365-XMACRO COMP is more concealable and more comfortable to carry than any other 17 round gun on the market.

The X-Macro is most popularly paired with the Streamlight TLR-7. Some details from Streamlight:
