Why the DB380 Wins for Concealed Carry
Having carried everything from 1911s to Glocks in my 18 years of shooting, the Diamondback DB380 hits the sweet spot for pocket pistols. The stainless steel construction resists corrosion better than alloy frames when carrying against sweat. At 11.2 ounces empty, it disappears in a front pocket but still gives you positive control during rapid strings at the 100-yard range we walk to here in Spring, TX.
