For: TM M9 Tactical Master Airsoft GunThis gun I purchased about 6 months ago. Now the gun is certainly not what it used to be. Lets compare the pros and the cons
-doesn't waste gas (about 2 clips to a fill)
-can be fired at a fairly nice rate of fire
-I counted about 27 shots i can fit in the gun
-the only things that aren't plastic are the inner barrel, the trigger, hammer, magazine, firing mechanism
-cant take much abuse (I'm already having to replace all the internals, and the plastic is already breaking on the slide)
-recoil is non-existent
-right trigger safety always comes off (and I lost the one I have)
Another thing that I didn't mention is the FPS. On a gas blow back the FPS has one major variable that affects it greatly, the temperature. So on a really cold day it will perform like shi*, and on a warm day, it will be your best friend.
I wouldn't recommend this gun to people that want a real one. Get a Full Metal gun, not a plastic one like this.
