Question: can i use metal bbs in this gun?
Document: I purchased this pistol in hopes to have a reliable long lasting gun. my previouse spring pistols broke on me within a few months.pros: great build (full metal), holds a lot of ammo, great weight,and very accurate.cons:the magazine becomse somewhat sticky after firing for a while because of the green gas and the safety is backwards than the instructions say.advice: load magazine before putting in bbs, only hold gas in for five mississippi seconds, and release gas after use
I am very pleased with this gun. It has full auto (which really uses up a lot of gas) and is made completely out of metal. It can hit hard and at quite a long distance. I am really happy with it and would suggest it to others (it is the sidearm I usually use for field games).
I bought this airsoft gun for a sidearm to my primary for airsofting. This gun has failed to impress me on the field. As it came through UPS, when I first opened the box up and held it, it feels very solid. The full-metal construction makes the gun sound beautiful when you rack the slide. The next day I filled it with gas and 15 bbs and shot it. After about 7 shots the blowback was not as crisp as the first few.
I really do not recommend using this on the field. It's a very poor gun. In fact after a month or so of using it under minimal use, the trigger spring broke down on me. I'm glad I only bought it for 60 bucks.
I actually bought this a long time ago and it is still in perfect condition. This gun means business, it's big, it's heavy, and it shoots like a dream. Not only is reloading this thing satisfactorily as.... I use it to shoot zombie posters, it's just the right model too, Overall this gun is just ballistic.. all I can say
Just got this gun for fathers day, and I must say it was all I expected and more. I took it to the place where we play Air soft. I used it in CQB and it performed extremely well, almost too well. At close range it really hurts so I had to use the bang rule at a greater distance than normal. However it was dead on accurate when I was able to use it. I then used it in field games, it really came in handy in the thick woods.
It is all metal, heavy duty so you don't have to be gentle with it. It fires just as well as the more expensive guns I have fired. The sound and blow back are awesome. So far no cons on this gun.
And the accuracy of this M9 Airsoft gun is actually better than the PX4 pellet pistol!The only nitpicking I have is that the rear sight is far too narrow for the pistol's front sight, and needs to be widened (I opened up the rear sight notch in ten minutes with a small metal file). And as stated above, the trigger is too good, and should be made with a stronger trigger spring for a heavier (more realistic) pull. Also, I wish it had a decocker.
Item had a glowing review about being very realistic and it is as far as the feel and look. Problem is bbs get stuck. Very disappointed.
(50 rounds of 9mm cartridges:  ten bucks;  50 rounds of Airsoft BBs with propane gas: about ten cents! ).
Answer: yes
