The factory replacement parts you can get from Smith and Wesson, as they now own Walther Gmbh. Any aftermarket parts, you can get from the internet. Just google "walther P22 parts" or if you are looking for something specific then enter that parts instead of parts. Its not hard to find the few parts that are being made for it.
Try egunparts ----------------------NEW ANSWER------------------ See the link "PPK/S" below for the complete diagram.
You can try JG Airguns, they have a few parts. You can also place a "wanted" ad on an airgun forum. LG 55 parts are scarce, but still around. Another idea is to buy a "beater" LG55 or a parts gun for the parts you need.
Read the directions for YOUR gun. CO2 does not explode, but may leak down.
Umarex SA177 Walther cp99 Compact Those are really cool co2 blowbacks that are from $50-$80
Smart Parts claims it does, but you have to change settings, and even then you risk CO2 bleeding into the gun and damaging it.
I believe you are asking about a Walther PPK/S made by Umarex. I would contact Umarex directly and ask them at Customer Service. See the link below.

No you do not need to put air in an airsoft gun. These guns are either spring powered where you must cock the gun before you shoot it, electric powered which are automatic and require batteries, or CO2 powered which requires a CO2 cartridge. This CO2 is not expensive and a pack of 40 CO2 cartridges costs only 20-25 dollars. the guns that require CO2 are not as common as the other forms of airsoft guns, although they are more powerful. In general, if you buy an airsoft gun, you do not need to put any air into it.
The Walther P99 was developed by the gun manufacturer Carl Walther GMBH Sportwaffen. The Walther P99 was made in the year 1996 and continues to be manufactured.
