I have been using a LH M2 since June of 2005. The gun works fine above 70 degrees. Below that, the gun doesnt consistantly lock the bolt. I also notice the bolt stops siding shut as fast after 20 shells and the inside is pretty dirty. I disassemble it after each Sporting Clay shoot and clean every component with Hoppes 9 and oil it with the Benelli Oil(one drop on each slide.
I shoot AA Super Sport shells, and have shot about 10 cases to this point. Any ideas would be great. I am about ready to go back to the Citori.
Thanks
Rick
