Why a 10mm 1911-style handgun? “It was our most requested caliber,” STI’s CEO Tim Dillon told me in a cozy curtained corner of their otherwise frenetic SHOT Show booth. And lo it did come to pass: an 8+1 capacity, 10mm handgun with a 5″ slide that weighs slightly less than a SMART car. And costs more than a month’s lease payment ($1514). Available in four months.
