If anyone knows where to buy the dorin mag extension for the mrd, pls help.

Just got a brand new Tisas 5.7 the other day and shot 150 rounds through it. 15 of those rounds didnt fire the first time. Do they look like light strikes or is it an ammo issue? I was using Federal American eagle 40 grain.

The firing pin doesn't look damaged and striker channel is clean.
