I know there are a bunch of glocks out there on the market now, Kwa's discontinued G series & ATP, WE's Glock series, TM's Glock series, and others... Found this today and I though it was interesting.
Canada based company, Skeleton Sidearms.

They are Canada legal airsoft guns, made in Taiwan. The glock series, G17 and G18c, look to be nicely made, with one minor drawback, smoked lower frame. While not a huge deal for me, it could be a deal breaker for others.
These are newly released (AFAIK) and have a pretty large price tag (in Canadian Dollars). G17 going for ~$260 and G18c~$280, ~$45 for 25 round mag, and ~$60 for a 50 round mag. Mag's are TM compatible.
Can't seem to find them in any US based site, only site I can actually find them on is https://www.buyairsoft.ca/.
