Toronto Airsoft got in stock right now the G&G GPM92 Gas Blowback Pistol. This GBB pistol contains what the company claims to be a "revolutionary rotating valve system" which should improve the shooting experience with a gas blowback pistol. Based on the M92 pistol, this comes with G&G markings instead of Beretta ones.  It has a drop free 27 round gas magazine and has adjustable hop-up.
