I like how comically large the sights on the suppressor look esp. from the top.
bet that thing's ridiculously quiet.
A local store around me has one for the low price of 15k, what a bargain! 
Your local gun store has some cool pieces
I am pretty sure it is the owners personal collection he just likes to show off. Tons of crazy weapons there including a M2, gatling gun, Rhodesian FAL,s Thompson's you name it. He must enjoy seeing people oogle over his pieces.
Rhodesian
Can someone explain the slide lock to me?
Behind the muzzle you can see a milled piece of metal that locks into a notch in the slide with a little pawl. This prevents the slide from moving backward when the gun is fired, reducing the sound emitted at the cost of the semiautomatic functionality of the weapon.
Ah, thank you! Luigi style.
Did Luigi/the Adjuster have a similar device? I know we see him manually cycling it
No I don't believe so. I think he just had to manually cycle it because it didn't have a "Nielsen device" or whatever. Which actually makes me wonder why the contraption pictured here is necessary.
This was pre booster! The quick-detatch nature of the silencer meant that you would lock it for suppressed operation, then remove the silencer for semi auto. The M9 will usually malfunction without a booster installed when using a silencer.
stops the slide from cycling to reduce noise. the user has to manually cycle it to chamber the next round
