I just picked up a maverick 88 security model. I took it to the range and tried several buck shot and slug loaded from Remington, Federal, and Winchester. The only brand I didn’t have a problem with was Remington. The issue I am having is failure to fire. I would shoot a few and it would go bang every time. Then I’d pull the trigger and here a click. When I would eject the unfired round, it would have a small light primer strike. After a second or third it, it would fire. The federal, and Winchester both did this periodically. I am uncertain what is going on with the gun. I insured that I cleaned the gun very well before it’s first use. I would like advice on how to fix this issue and make this gun as reliable as I know it can be. Thank you.
