The 4.0 ShapeShift Sig Sauer P229r 9mm IWB Holster is an evolution of the IWB design, giving you a comfortable carry and easy concealment with features unlike those of any other IWB for this make and model pistol. You won't find a more comfortable carry anywhere else in this or any other galaxy. The ShapeShift shell system lets us reduce the overall footprint of the holster base, so your Sig P229r 9mm concealed carry holster occupies less overall real estate. That makes for a more comfortable carry. Alien Gear also installs a backing layer of CoolVent neoprene on the holster base. This fabric layer cushions but also breathes against bare skin and wicks away moisture, so your Sig P229r 9mm IWB is comfortable to carry all year long. The edges are bound for even greater comfort. The core of the holster base is twin layers of spring steel and woven ballistic nylon, giving the holster a firm but flexible spine. This gives you the support your gun needs but also ensures a long service life. The ShapeShift shell is custom-molded for the Sig P229r 9mm, even for railed pistols. You get a custom-quality fit right out of the packaging. No break-in time is needed; it comes ready to go. Passive retention is fully adjustable, without needing to use tools of any kind. Ride height and cant angle are also adjustable, without needing tools.
