The Umarex (GHK) Glock 45 is a 1:1 airsoft recreation of what is commonly regarded as the most usuable and practical Glock variant produced in the last 10 years.
Manufactured by top end airsoft manufacturer GHK and fully licensed by Umarex.
The G45 falls into the categorty of a crossover pistol, with a full sized frame and compact, shortened slide.
It sports an authentic looking aluminum side with Cerakote finish, perfectly mimicking the look and finish of the real steel.
The slide sports front and rear slide serrations making for easy slide manipulation and tactile grip.
As it is a fully licensed replica, it sports genuine laser engraved Glock markings on the slide and magazine and embossed markings on the frame.
Because this is an MOS variant, it has the removable RMR top plate, allowing the attachment of an aftermarket optic (not included).
Lots of metal parts, include a CNC aluminium slide, outer barrel and magazine, steel front sight, guide rod, trigger safety insert and slide release.
Beefed up recoil spring gives a snappy blowback. Guide rod is comprised of a steel/polymer combination.
Gas blowback operation. Charge standard green gas (135PSI recommended) into the hidden fill valve on the base of the magazine. This gives over 40 shots at room temperature and a reciprocating slide on every shot. The slide locks back on the last BB fired.
Magazine is a super lightweight aluminium design, closely matching the weight of a real magazine. Only accepts GHK style G series magazines.
Disassembles just like the real steel via the disassembly lever.
Stippled polymer grip allows for comfortable shooting in all conditions. Lanyard loop located at the base of the pistol grip.
Adjustable hop-up via the small flat head screw on the base of the hop-up chamber. Slide removal required to access.
Note that the trigger wall is very far back on this model, just like the real steel. The trigger is required to be depressed fully rearwards to fire the pistol.
BB loader included.
