Cindy, yes, a shotgun with a 3" chamber will safely fire both 2 3/4" and 3" shells. Have a great day!

Cindy, it sure will. Since this has a 3 inch chamber it will safely fire both 2-3/4 inch and 3 inch shells. Since this is semi automatic I'd recommend standard to high velocity 2-3/4 inch shells to completely cycle the bolt. Hope this helps

Cindy, yes Ma'am. Since this shotgun has a 3 inch chamber, it can fire 3 inch and shorter 12 gauge shells (2 3/4) no issue. It is recommended to break it in with high power shells (50 or so) initially and then clean and re-lube.
