Sig Sauer Pistol Frames for Sale

SIG SAUER, Inc., from Switzerland and Germany, helped pioneer modular, replaceable pistol frames, introducing them with the P250 (2007) and making them central to the P320 (2014) and P365 (2018) platforms. Built around a serialized FCU, SIG’s factory, non-serialized grip modules come in multiple sizes and materials, including polymer, tungsten-infused TXG, and aluminum AXG, with ergonomic textures and integrated features that let shooters fine-tune fit, capacity, and recoil feel.
