I thought there have been reported problems with Blazer -- or some of it -- can't recall the details. This is not a factory recommended round.
Frankly, with all the issues with this gun of lubrication, ammo, etc. -- I can't keep track of it anymore. Did you ever shoot it after it came back from the factory with the factory lube and with actual first-rate Gold Dots?
I agree with Justin -- its time to call it quits. I would talk to Eric about getting a refund -- they don't have to give you one, but they might. If not, try and sell it here. I would buy it from you if I was in the market for a second.
For whatever reason -- whether its you or the gun or the gravitational field in your area -- this makes two R-9s that have not worked for you. Its not worth the hassle or the effort. This is not meant as an attack on you -- its just common sense at this point.
