I have a Ruger 40SRC that is not feeding correctly. I feed the first round fine and than it jams. It is a newer pistol with maybe two hundred rounds through it. After close inspection, it look like the fireing pin is protruding to catch the lip of the rim. It will happen 3 to 4 times per mag and than correct itself. Put in a new mag and it starts all over again. I don’t think I am limp wristing it.
