Crosman still has parts for the pistol. You can order directly from them. Crosman has all their Owners manual and Parts manuals online. See the link below. When it opens scroll down and click on "download Manual/Parts diagram". Then select "Crosman Pistols". From there you should be able to locate you pistol's diagram. After you figure out what you want go back and call Crosman Customer service and order the parts. I've rebuilt 4 of the 357's this way.

Get the pistol, preferably a 1911, you get better velocity, and a smaller easier to carry pistol.

Here are two reasons why you do NOT want to leave C02 in an air pistol. The constant pressure on the seals will eventually cause them to distort and leak. If someone else picks up the pistol they can discharge it accidentally. For the few cents it cost for a new C02 powerlett it is not worth keeping it in the pistol. I leave my Co2 guns charged with Co2 all the time. According to Tim @ Mac1 airguns, he told me to leave it charged with gas. Reason being is that it keeps the seals seated and and valve clear of debris and dust. It will also tell you if your gun has a leak the next time you shoot the gun. If the Co2 is gone, you know you have a leak.
Use Waddcutter pellets, or Target pellets. Don't use BB's for target practice they are not as accurate as pellets. BB's are okay for plinking.
It is possible.
It was designed for BB's .175 or .177
