well first of all, you can't order from airsoft GI as far as I know, be sure to check out the top of this page under canadian retailers to buy guns from
as for the paint, all (if any just a few) are orange paint free. I believe Airsoft GI or whatever is American and its mandatory to have it painted on there as part of the american law for airsoft. Here it is legal to not have it so don't expect guns imported into canada to have them unless otherwise stated.
As for the glossy look, I read about that too but there are lots of reviews out there saying that the gun shines more in the light but not to an extent where it looks too "fake". Its debatable but I took all those things in consideration after 2 months of researching. Google "KWA Glock 19 Reviews" and you should find all the information you need

Also note that the KWA Glock 19 does not carry the trademarks anymore due to legal issues with Glock.
