Nice, it's obviously genuine, though I can't be sure it's not the decocker on a semi auto but what ever, it gives it versatility anyway.
The only two problems are this. First, it has echo, so it can only be used in certain scenes, I suggest recording in a closet with a mattress against the door if possible, or any other area with carpet and thick fabric. I know it sounds strange, but the clothes on one side and the mattress on the other massively reduces reverb.
Second is that you got a bit too close to the mike, try recording it three or four times and listening to it closely to find the best version.
