The G21SF is one of the best pistols when it comes to handling, thanks to its shortened length of pull. Combine that with the intuitive engineering that comes with any Polymer80 products, you’re in for one hell of a build. This frame is crafted from a hardened polymer to ensure both a lightweight a durable structure. It features an extended beaver tail and textured grip for an improved control and handling.
