Best IWB Holster for the Ruger LCP Max

July 1, 2026

The Ruger LCP Max shrinks a 10+1 .380 ACP into a pocket-sized frame that's about as easy to carry as a cell phone. It's the definition of a deep-concealment, always-with-you pistol — and it carries just as well inside the waistband as it does in a pocket. Here's the best IWB holster for the Ruger LCP Max, and the exact size to order.

The Best IWB Holster for the Ruger LCP Max: Mainstay™ Clipless IWB

For the LCP Max, we recommend the Mainstay™ Clipless IWB Holster in size 11. Because the Mainstay is a clipless, silicone-coated design, it works equally well tucked inside the waistband or dropped into a pocket — no belt clip required — which makes it a natural match for a pocket pistol like the LCP Max. It covers the trigger guard and stays put without printing.

LCP Max (bare): size 11
+ weapon light: size 10

The LCP Max isn't cut for a red dot, so there's no optic size to worry about — just pick size 11, or size 10 if you run a compact light.

Why the Mainstay Works for the LCP Max

A pocket .380 only helps if you actually carry it, and a bulky holster defeats the purpose. The Mainstay's thin, flexible body keeps the LCP Max discreet whether it rides IWB or in a pocket, while still securing the pistol and protecting the trigger. It's made in the USA and priced under $35.
