XDMike,
You have a few choices - you'll have to decide which is right for you.
For home practice to draw and get some "dry fire" trigger time. This is not an all inclusive list. Just a start.
1) Just dry fire exercises - there are a lot you can find on a simple google search.

2) You can use some "snap caps" for dry fire in addition to the above.
3) You can go with a safety barrel replacement.
Something like these:

They replace your barrel with a plastic barrel - for maximum safety.
4) Get an airsoft replica - you won't need the most expensive ones. Most models are available. The most common ones are running anywhere from $60-$125. They weight the same, functions and shoots great at >30-40 feet. You may have to find a close look a like (size and feel for some models).
You can learn a lot doing the dry fire exercises but do know there are limits. Nothing replaces actual live fire (recoil control) but for the cost it wins hands down.
For anyone new to firearms - there is one thing most do not look at.... get some instruction.
You can't practice what you don't know. You'll build bad habits, unsafe handling and it's tough to loss those later on. Invest in some instruction by a qualified instructor in your area. Then you can truly practice what you need to learn.
Invest $40-$150 to learn it right the first time. It'll save you loads of ammo and some major headaches later on.
Hope this helps.
