The SFX9 4-inch was Wilson's first production pistol designed from the start for optics, with a slide cut and co-witnessed suppressor-height sights included at MSRP. The 1911-style single-action trigger in a compact optics-ready package filled a real gap in the market. It runs suppressed or unsuppressed with equal reliability.
