Absolutely loved this gun. Very realistic, full auto fun switch is a nice trick too, I have owned all the glocks including the t4e .43 cal and this is up there with my favs: G19x , and Gen5 T4E .43 cal. I need to buy a new one now because I stupidly sold mine.

update to review, the Glock G17 gen 4 mag works with this pistol. In fact my only complaint with this pistol is my mag broke right away. however the the Glock G17 gen 4 mag not only works great on this, but seems to be easier to load.

Got it during winter but wsa only able to fire it last weekend. This gun is great good kick semi or full auto, gun is a bit light but mag is heavy, thos giving the gun good overall weight... aiming is verticaly correct but horizontaly low 2inch at 11meters... Full auto is a bit hard to control because of the good kick. And the mag from the Umarex G17 gen4 are very compatible (tried and confirmed), now I have 3 mag for both gun...
Do I recommand it, YES, do not hesitate...

Very impressed with this gun. Very realistic, semi auto kicks hard, and the full auto is insane! Seems to be difficult to find extra mags for this piece, however I have read that the Glock G17 gen 4 will work. I may buy one to test.
Great price, and was delivered fast.
