i was given a barley used auto loader that was my great grand dads, i took it out a few years ago and was just target shooting with it. and given that it was an older gun i decided i wouldn't hunt with it due to it being in too good of shape. but after shooting the last shell out of it i set it back in the case and drove home not hitting the release button on the side by the trigger to close the evac slider on the side of the gun. now when i hit it nothing happens wont shut. i am wondering where someone would recomend taking it to have it unjammed. or if anyone had experence with autoloaders and have experienced this problem and knows how to fix it . thanks
