I have searched everywhere for a longer barrel for my SP01 and have come up empty handed. Maybe I am just looking in the wrong place

The reason I want one is so that:

a. Accuracy could possibly be somewhat increased.

b. Attachments to the end of the barrel could be made.

i.And no, I do not mean any illegal things.

-I read the rules

c. May improve looks?

Basically I have gotten into the idea of making a muzzle break or porting the barrel like that of the CZ Champion. I figure it can't be that hard to thread the end of the barrel and make a break that would look like the Champion, only blued If you have any info on this please feel free to share While I am at it, has anyone ever seen or heard of being able to have a red dot and/or magnified scope for the CZs? I thought I saw a sight rail riser that would attach to the accessory rail and go around the frame and slide to produce a rail above the pistol.

IF SO:

Do you think that the rail would stay in place? Or would it move around and such?

Thanks in advance for any help
