From Argentina - don't have the specs for the "Detective" handy - its more or less standard issue for LEO's here, especially officers, both Fedral and different Provincial police. Its quality is very good (FM, 'Fabricaciones Militares' usually is - depends on the Defense Ministry which has had a more generous budget in the past than others). It handles much like a regular HP, IMO the shorter barell makes almost no difference. Beware of second hand FM's - many could be shot out as they can get a lot of range use - on the other hand, some are hardly used at all and good bargins.
Hastas pronto!
