Gun Shields: A series of shields with a pirate age gun attached. And due to the magic, they don't misfire, and they automatically reload when they're switched out, albeit with cooldown periods. Requirements: Black powder, and DLC.

Model 1: Gun shield. A real world weapon in the form of a small dhal shield with a flintlock pistol going through the middle of the shield for shooting the opponent.

Model 2: Tower shield with a musket.

Model 3: Knight's shield with a blunderbuss.

Model 4: Tower shield with a Nock's Volley gun, (7 barrelled musket.)

Model 5: Tower shield with a Perdition to Conspirators! 14-barrel flintlock rifle. (This gun was owned by Colonel Thomas Thornton, who was once betrayed and mutinied against, and it affected him deeply. One of the things written on it was 'With this alone, I'll defend'. It also had a second stock with a motto engraved on it that says 'La vérité gagnera', which translates to 'Truth will Triumph'. Everything about it just seems to fit with Naofumi almost too well.)

Model 6: Tower shield with a Chambers flintlock machine gun. Fire it once and it'll keep firing for almost 2 minutes straight until all 224 rounds have been expended. (Yes, this 17th century gun was real, although it wasn't attached to a shield.)

Hero's Levelling Shield: A weak shield with low stats that offers 500% increased experience from defeated enemies. Great for levelling up faster, terrible for dealing with stronger foes. Requirements: DLC.

AN: By the way, I read another manga a while back that also uses stats and levels like Rising of the Shield Hero, and their rules for guns was that their abilities were completely independent from the levels and stats of their users. Making them completely overpowered in the hands of someone with a low level, but complete garbage in the hands of someone with a high level. Made sense to me that they could work like that in the Rising of the Shield Hero world.
