Very reliable and relatively cheap.

it comes with 2 different size replacement grips. Very comfortable. Trigger pull is very short and extremely smooth. Accuracy is very satisfying. Front sight is fully adjustable. Co2 usage is more efficient than some products, such as GAMO pt-85. Shots performance does not decrease so much until the last shot. And when the CO2 runs out of, you hear it by a gas sound notification. Only downside; it is a boring while loading the bbs. Because the hole is narrow, the spring is too tight and there is no simple component to hold it steady.

My new favourite

This is my 5th blowback air pistol purchase, and this is my new favourite by a large margin! The slide spring is snappy, and it shoots excellent groups, and the trigger is light and crisp. The adjustable hop-up is nice although I have yet to play with it.

New mag

Sadly the magazine has given up the ghost, the value seems to be leaking, will be either looking for the parts for the magazine or a new mag, this air pistol is well worth keeping
