The 357 sells for about $50 in the USA. If you can find it cheaper, go for it. Or you can purchase a used one off of Craigslist. But I would check it out and test it first to make sure it holds a charge.
This is a Crosman Quest 1000. See the link below
The Crosman 357 is modeled after the COLT PYTHON. If the Python fits the holster, then the Crosman 357 may also fit. Your just going to have to try it.
It's a model of a COLT 357. Just like the Crosman 1077 is a copy of a Ruger 1022. Several of Crosman's air guns are modeled after real firearms.
You take off both grips. The C02 nozzle faces up into the gun. Tighten it as tight as you can and make sure you tighten it as tight as you can. I also recommend you use pellgunoil it increases the maximum FPS and keep the seal nice and tight. If you use the pellgunoil it will keep your airgun working like new for as long as you can keep it.
