Sound Effect on a Trigger, Don't know how

Ghostly Greetings.

I'm starting to design a home-made steampunk gun. So it will be futuristic-retro. I can probably get some flashing lights from toy guns or something, but I'd like it to have sound, also. The sound boxes on toy guns are awful, maybe 5 year olds like them, but not me. They are tinny, scratchy, and barely resemble a bang.

I'd like to record some gunfire (probably from Call of Duty, they have some good electronic pulse gun noises) and have it playback, LOUDLY and clearly, whenever I pull the trigger.

I'm not adverse to buying something like a tiny MP3 player and speaker, but i don't know how to actuate the pushing of the button via a trigger.

Anyone have any ideas? Thanks for reading.

Something like this will work, your SFX files go on an SD card (card fits into socket on the bottom of the board). To trigger it, use your guns trigger as a N.O. switch between GND and PIN 1 on the player. Everytime you pull the trigger it will play your sound file. You won't have control over the length of the sound with the trigger, it will play your entire sound file each time. If you make a short sound file, you can control it better.http://m.ebay.com/itm/SD-SDHC-Card-...l-3-3V-5VDC-/301496277847?nav=WATCHING_ACTIVE

I already ordered the J-man suggested piece, but then did a bunch of reading on the website suggested by Jeff. I'm kind of getting an idea on how these work now and will probably be able to piece together something.

I see these aren't polyphonic, but that's fine. I was thinking of having the gun have three switches, each one would be some kind of a rising tone, and they would indicate 'power levels'. when the third switch is pulled, then it can be fired with the trigger.

Thank you both J-Man and Jeff, these little boards are very much what i was looking for! Push button sounds that i can create!
If you look at the picture that shows the bottom of that player, the pins are labeled. Actually there are just holes for pins, you can solder pins into them or solder your wires directly into the holes. You can direct control up to 8 different sound files with switches or buttons. The direct control pins are active low, which means when any of them are touched to GND, it will play the corresponding file. It can only play one file at a time but it doesn't have to finish one file to play another. If it's in the middle of playing one file and you trigger another pin, it will play that file. Your files have to be renamed 1001.MP3, 1002.MP3, and so on up to 1008.MP3 (files 1-8). BTW, it also plays WAV files. Here's the link to the data sheet for that player. http://mdfly.net/Download/Module/AU5016.pdf
