The NUPROL Perfect Fit Airsoft Holster Big Bird M&P Series is a retention holster specifically designed for the dimensions of Airsoft replicas, particularly those in the WE "Big Bird" (M&P) series. 
 
Key features of this holster include:
Specific Design: It is tailored precisely for airsoft M&P models, which often have slightly different dimensions than real steel counterparts, ensuring a secure fit.
Quick-Draw Release Lever: Features a button release system positioned for rapid and smooth drawing of the replica while keeping the trigger covered to prevent accidental discharge.
Durable Material: Constructed from a strong, law enforcement-grade PA6 Nylon polymer for durability and a balance of rigidity and flexibility.
Adjustable Angle: Equipped with a 40-slot, 360-degree orientation panel, allowing you to set the perfect drawing angle.
Mounting System: It comes supplied with a hip/belt retention paddle for immediate use. It is also compatible with other NUPROL Perfect Fit accessories like drop-leg platforms, MOLLE adapters, and shoulder harnesses (sold separately) for various carrying options.
Hand Options: The product is generally available in both left and right-handed options, though specific availability depends on the retailer.
