I can tell you now that this is indeed a model all it's own, I checked, and yes it and the Semi-auto magnum have similarities but are not the same, And of course the colors are off, because we all know that in real life the Baretta M9 is not white, Just a minor detail that though, although it does make it seem un-professional.
Just another thing I noticed that doesn't really matter, but the iron sights on a pistol or any gun would not be 1 bar (or w/e you want to call it) on one side and one on the other, it is a 1 bar on the front, 2 bars on the back.
And just a personal annoyance, is the firing sound, not to say gun's aren't loud, but it does hurt my ear's a little even on somewhat low volume, and same with (what I believe to be) a shell case hitting the ground? I do not like that sound :/
But fairly good job, at least it's it's own model, that's all that matters.
(Please do not flame because I am giving him constructive criticism, or at least that's how I look at it) Ninja!
