John,
No is the answer to your question. It has been an unusually cool and rainy summer in New England and I haven't gone to range much. However, heat and humidity have finally caught up with us and I am more likely cooling off by staying indoors or swimming in the river that goes through the property.
I am an autumn guy and that is around the corner. That is when I shoot the most, before leaves fall and it gets too cold.
My initial concern about my Robar R9 has gone away. That was a tendency for the trigger to stick when I dry fired it. So, my Robar R9 is carried everywhere I go and I stare at it, in admiration, about 37 times a day.
