I have a brand new Mossy 500 bantam 12 gauge. I cleaned it up a bit the other day and then put it back together. I followed the directions in the manual for the function test and when the trigger is supposed to click it clicks. However, if I put in a "traditions" snap cap and cycle it through or place it in the chamber, then rack the slide the trigger will not budge. Is this a problem with the snap caps? Any suggestions would be greatly appreciated.
