Please dont shoot slugs through a 32" barrel A5. That is undoubtedly a full choke and shooting slugs through it can damage that barrel, which by itself is worth $300. Slug barrels are typically 24" in length with an Improved Cylinder choke.
NO! The 1187 barrel was for remington shotguns,the auto-5 shotgun is a browning shotgun.

Providing it is a Auto5 which wasnt noted, it would have been made in 1929
This gun was made in 1929. The barrel address should say: BROWNING ARMS Co OGDEN UTAH.

It shouldn't say light twelve on the barrel, but on the receiver. Light twelve means that the gun is a light weight version of the standard Auto5 shotgun.
