    I understand that on some semi-auto shotguns, shortening the barrel can affect reliability with light loads. Is there a way to correct this? The gun in question would be a Winchester Super X3/FN SLP and the barrel would go from 22" to 18.5"
     
    Avoid mossberg semiauto shotguns for anything more than just range fun. The most reliable one ive had experience with still required a detailed cleaning after 4 boxes of shells. Most of them are single shots based off the 4 Ive messed with.
