Stripped my M2 down except for the interia spring the owners manual never mentioned the inertia spring,gave it a good cleaning went out and shot a couple boxes of heavy field loads no problems,recoil seemed to be no worse than my 1187 the only difference I can see is it shoots as fast as I can pull the trigger. I do have 1 question with a boresnake do I put a little oil on it or just run it through my barrel dry. Thanks
