The Tactical Response 4 incorporates a much requested sliding safety (on the front of the handle). The TR-4 features a 4" black coated CPM-D2 blade (plain). The ergonomic handle is custom Vintage American Flag anodized T-6 6061. The TR-4 fires hard, locks up like a rock and feels great in hand. The TR-4 has a pocket clip (tip up) for easy carry.
