FX Impact M3 .357 questions.

Are the .357s setup as slug guns from the factory with the high power kit installed?

What barrel liner comes with the gun? Is it good for both pellets and slugs?

Why are the bottles no longer 310 bar, especially if the guns are capable of 300 bar fills? Can I order the gun with a 310 bar bottle upgrade instead of having to replace it entirely? My MKII purchased 1/8/2020 has a 310 bar 580cc bottle.

Thanks. Thinking about thinning out the Auto-5 herd and getting a .357.
 
They only come with a 250bar 580cc bottle and with the regular liner not the heavy. They really only shoot pellets but others have had some success with slugs. I actually am sending mine back tomorrow or Tuesday due to a regulator failure issue on the first regulator, I think.

It is a nice rifle even though I need to send it in for service and would purchase it again. Have been told from FX that they are perfecting the slug liner and hopefully it will be out soon along with the other items they have been showing lately...
