The Mark III RP variant uses the replaceable 1911-pattern grip panel frame, here fitted with tan textured panels for a secure hold. Its alloy-steel blued upper pairs with a durable Zytel polymer frame to keep weight manageable while maintaining rigidity.
Factory configuration omits iron sights and includes both top and bottom Picatinny rails, allowing direct mounting of optics and accessories. A Bushnell red dot is already installed, providing a ready-to-use sighting solution.
The 4.5 inch alloy-steel bull barrel is threaded 1/2x28 and includes a thread protector. The barrel uses a 1:16 right-hand twist to stabilize .22 LR, and the simple blowback, single-action system runs an internal hammer.
Safety features include a thumb safety, loaded chamber indicator, magazine disconnect, and internal lock. Capacity is 10+1, and this example includes three factory-pattern steel magazines. Made in the USA, this model is cataloged as P45GMK3PRRP (mfg part number 10149) with production in 2011.
