There is a reason MX3 barrels are cheaper, the MX3 was I think a cheaper version. I was at a shoot many years ago and a native Canadian was using an MX3 which rattled like castanets it was so loose. Of course you must realize that the MX 3 Special is a different gun altogether.
How many of you have owned a MX5C? I did and part traded it off
for my first MX8. Lots to know about P guns.
