UMP45 with Holo A, Extended Barrel and laser for extra range damage, Super Shorty with Iron Sights and laser as a pocket shotgun backup, and Proximity Alarm as the default utility.
Why it works
Extended Barrel trades recoil control for extra damage at range: worth it since Castle plays a patient, positional game behind his barricades rather than sweeping for first contact. Holo A keeps peripheral vision clean, and the laser speeds up aiming down sights for closer trades. The Super Shorty only offers Iron Sights and nothing else, so it's mostly a fixed pick with a laser on top.
Who it is best for
Players who want Proximity Alarm as the default utility: early warning on the exact approach Castle's barricades are already funnelling attackers toward.
Attachment roles: the laser aids aiming speed, the angled grip aids reload speed, and the horizontal grip aids movement speed. Ubisoft attachment rework. Check available options in game.
