This is my first airsoft gun, but not the only gun I have ever shot. It is heavier than I thought, and feels very realistic. It has great accuracy. My only complaint is that sometimes, maybe once every 20 shots, it will fire two bbs at once. It is supposed to hold 15 rounds, but I got it to hold 17. I am using 12mm bbs, which work well.
This is an amazing beginner gun because it is very durable and has a low fps. It shoots very straight and it has never jammed on me .
This is an accurate gun with lots of power. It is heavy with sturdy feel. Works great even after a year. Love to shoot with it.
This airgun work ok for the price. The model that we received shoots a little high which frustrated my son a little. Still, he enjoyed the detailing of the air pistol and the realistic, heavier weight.
They give you a holster with the gun, I know alot of people have said that it doesn't fit. It does fit, but it's a snug fit. Sometimes when you put the gun in or pull it out, it will hit the safety switch and put it on safety or take it off.
Answer: no
