"Police seizures of guns in other cities, including Chicago, also show a growing share of large-caliber handguns."
Even as the .40's share of the new gun market dwindles, the used gun market is awash in .40-caliber department trade-ins. When a poor person needs a cheap gun for home defense, a $299 ex-police Glock 22 is a compelling purchase. Improperly secured guns stolen from family members are the likeliest source of crime guns.
