Speaking of unique firearms, I recently stumbled upon this Dan Wesson Commander Classic in .45 ACP on https://uspatriotarmory.com/product/dan-wesson-01912-commander-classic-ca-compliant-45-acp-81-4-25-match-grade-barrel-forged-stainless-steel-frame-w-beavertail-serrated-stainless-steel-slide-brushed-finish-diamond-checkered-cocob. While it may not offer the same modularity as the Sig P320, it certainly brings a touch of classic design and modern features to the table. With its match-grade barrel, forged stainless steel frame, beavertail, serrated slide, and diamond-checkered cocobolo grips, it's a work of art in its own right.
