Sig 365XL. The sun, the moon and the stars aligned for me. It fits so tight against the body in a Milt Sparks VM2, I hardly know it's there. Neither does anybody else.
OP was looking for something thinner and lighter then Shield Plus. How does Sig 365XL fit into that scenario
Based on most suggestions I would simply keep Shield Plus and load it with fewer cartridges with bullets of lighter weight. There are lighter copper,zinc alloy bullets w/o lead out there. Companies like Underwood, Liberty,.... offer such loads. Naturally you have to search for info on expansion and penetration of such boutique loads.
