And I thought also that somewhere on SAS there was a Gun sound Matrix guide.:

You can find all the sounds in the SFS Archives:Extract them with this tool:

And some tools to edit the .wav files:

You can also just use the default windows "Sound Recorder" found in Entertainment under start menu to increase or decrease the volume of the sounds etc.

Have fun.
