Pros:

-Built in laser sight
-Compensator if you have 2 pistols
-NO dumb@ss flashlight thing on the bottom
-i actually dont use melee weapons anymore thanx to  you
-Nice sound

Cons:

-looks kinda plastic
-the sound when you pull them out and it normally clicks, it sounds like a voice or a loud beep or something

Conclusion:

very impressive mod, probably my favorite pistol mod for right now. Ironically enough i had literally JUST finished testing and downloading another M9 mod released today then i check back on the website and see this and all i could think was: OH. MY. GOD. this is amazing
