"Just received the Matrix Poseidon Custom Airsoft M9 (Full Metal Silver).

Build Quality: Shaking it while holding only the grip, there's a bit more rattle than I'm used to. Put a finger on the slide while shaking, and it's quiet.

Finish: Most of the unit is finished beautifully, some rough spots near the front, and in the well where the safety is located. All in all, very very nice.

Weight: Gun without magazine comes in at an "evil" 666g. Empty magazine is 253g. Realistic feel.

Fit: After having tried a few M9 class pistols, the grip is consistent, and is slightly big for my hand, but still able to grip well. All buttons and switches are within easy finger reach while gripping (except the slide release switch/lever)

Trigger: Made of metal. Wall is near the end of travel, and trigger needs to be returned near home position to fire again.

Magazine: Made of metal (Silver for this model), has beautiful finish with no markings. Holds 22 BBs.

Gas Efficiency: 27 BBs per fill (Green Gas) at an outdoor temperature of 66 degrees farenheit.

Firing Action: After firing 4 magazines, no misfires and/or jams.

Slide Action: Smooth and solid. Very little "play" (not enough to negatively affect overall impression of quality). Slide opens on last BB (empty mag)

Accuracy: 4 magazines with groupings at 50ft average within 6 inches (pistol was stabilized). All BBs hitting target.

Teardown: Easy. Depress button, turn slide release and move slide forward.

Notes: Overall a fantastic feeling pistol with nice feedback (GBB). Despite reading otherwise, the safety on this model does not act as a "decocker". Without a magazine , the pistol action is such that pulling the trigger auto pulls the hammer, and you get a "click" with the hammer returning home after completing the trigger pull. With the safety in the ON position, the trigger freely engages with no tension.

Final Disposition: Would've been nice to have a decocker, but I would recommend this to anyone looking for an M9.

"Great weapon. I don't know the fps on it, but I rip holes into the cardboard box. Pretty sick. Give it also 5 stars for authentic feeling
