the odds of someone wearing out a 1187 are slim in my opinion. i have friends that have shot 1100's for years, one is a 3 digit serial number that shot over 350,000 skeet loads in a 12 year period, the 1187 is basically they same gun. i do know of one 1187 that has been used for duck and goose hunting since they came out plus 3 flyer shoots a year, this gun has had a steady diet of 3 3/4 or better dram loads with no breakage. the 1187 mentioned above is used in texas, arkansas, kansas, nebraska, north dakota, minnesota, wisconsin, mississippi, louisana and georgia......he has the time and money to hunt all these every year, if that gun gave trouble, he could buy any gun he wants, he's still shooting it. all of these have had the o-rings replaced except the old three digit gun, it's owner is trying to see how long it will last, he takes it out and rolls it between his fingers before shooting sessions. i guess they will out last most normal shooting situations.
