The new 4.5mm UX SA9 looks to be similar to the existing HPP and TDK45 pistols. It could be described as a member fo the generic Glock family.
It is a CO2 powered, blowback replica with a crips and fast slide cycle.
The frame of the pistol is polymer with a metal slide. It's funny that it bears engraved SA9 markings on the slide.
On the frame there is a Picatinny rail that allows the attachment of various tactical accessories.
The 4.5mm version features a 20 round drop-out magazine and a power of around 400fps (125 m/s). The user can shoot up to 150 shots from a single CO2 cartidge, very impressive performance from a blowback replica.
The 12 gr CO2 cartidge is housed inside the grips and replacing it is very easy and fast due to Umarex's fast changing system via the rear grip panel.
To make things safier, there is a manual safety located on the right hand side of the pistol, right above the trigger guard.
