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.

Not sure what to change? Compare attachments with a repeatable practice routine.
