Product Overview
Rock Island Armory RI51529 is an M1911-A1 Pro Match metal-frame centerfire pistol chambered in .45 ACP with a 6″ barrel. Verified seller attributes include an extended beavertail, a fiber‑optic front sight, and an integrated Picatinny rail. Package quantity is 1 (SKU RI51529).
Why This Product
The extended beavertail (source: product-276291:f009) affects grip and slide‑to‑hand interface on a 1911 platform, the fiber‑optic front sight (product-276291:f010) changes the sighting profile for faster front‑sight acquisition, and the Picatinny rail (product-276291:f011) provides a standardized interface for mounting accessories. These are the primary, verified attributes buyers use to compare 1911‑style pistols.
