Ok, How offen will the"O" rings need to be replaced. How light of load will the 712 or 912 accept, 7/8, or 1 oz.? Assuming that it will be cleaned after each trip to the range (100 rounds skeet, 100 rounds of trap, or 125 rounds of sporting clays) at least once a week will it keep on "Ticking"? I have an old 870 with at least 85,000 Plus, Benelli M-1 super 90 with about 60,000 rounds, & a Beretta 390 (I got used) with unknow number of rounds.
I was thinking about picking up a pair of CZ's, and giving one to my Son & one to my Son-in-law. One Marine, one Ranger, both believe you should clean, maintain, and shoot the wheels off.
