but I'm very embarrassed that I can't figure out how to disable the safety _(_ _)_

This is nice, I'm pleased to see that all the functions of the gun are accurately depicted; there's only one problem though, when you click on the slide and rack it, an empty casing flies out, when it should be an unused round. Other than that, though, good job.

Like I said it shows how the pistole is used and the ammo capacity of a glock, but not to sound like a jerk, it would improve the quality by adding a echo effect along with shots that all don't sound the same. But great job

Not the most riveting thing on the internet, but it all works, with good sounds and OK music.

You could add a pointer to how to reload it, it is not obvious to everyone.

You might consider adding more links and info, such a reference to the Glock Group- maybe a link to their Wikigrounds page:

http://newgrounds.wikia.com/wiki/Gloc k_Group

also a link to the Wikipedia Glock page, or some other photos of the gun.

If it had a breakdown option to show the inside workings, it would become really interesting and developed.

It is certainly different, although I don't believe that it is necessary to pull back the slide when re-loading if a round is chambered, and it would be really cool if you actually had to drag the mouse to pull the trigger and unlock the slide. Not bad though.
