"bought this gun around thank giving time and had a great deal on it
my first ever GBB pistol, and the only comparison i have is the KWA ATP(glock 18 replica)
personal i hate the trigger guard on any glocks so glocks are not in my list at all
looking at the reviews, i chose this one nearly no one else using
was trying to get the march compensator one but it was out of stock during that period:(

using .23 BBs on both pistols

weight : relatively heavy Much lighter

Rate of fire: moderate Fast
due to heavier and
longer trigger pull

recoil: strong Moderate

feels : very robust quite plastic

sound: BANG BANG BANG bang.......
just dont try to stealth with it

Accuracy : 85% accurate 90%accurate under 50 feet
might go heavier BBs(.25/.28) definitely curving over 50 feet
for better result, rounds feel
a bit curving over 50 feet

spare parts /
attachments: hard to find any... should be a F ton out there?...

Mags: heavy lighter

so over all its a very promising GBB imo
N2 gas system can guarantee 2-3 mags 1 fill depends on temperature(was doing indoor around 45 degrees F and it might lose pressure after like 20 quick shots, need to warm it back up)

the barrel is full plastic and the orange tip is PART of it, u cannot screw off, only way is either changing the barrel or simply spray paint it....

"Fantastic gun. Very very accurate and incredible range for a pistol. It puts my TM 1911 to shame. Huge gas capacity 3+mags per fill.
This gun is a little temperature sensitive and is prone to icing so it doesn’t work well as a primary but is a fantastic secondary weapon. The BBs fly right where you point the gun. Easy to acquire and hit your targets even at a distance.
