Resident Evil 3 · Weapon upgrade
M3 Shotgun: Semi-auto barrel
The Semi-auto barrel is listed as an M3 Shotgun upgrade, with the guide pointing to Downtown Gun Shop Kendo.
How it works
The guide lists the Semi-auto barrel among the M3 Shotgun upgrades and directs readers to Downtown Gun Shop Kendo on the first floor. It supplies no further acquisition condition or description of how the barrel changes the shotgun, so those details are unspecified in this reference.
