...[I] have heard of home bluing kits and some ofthem are as cheap as $20
No "home bluing kit" will affect chrome plating.
Nothing will stick to chrome, which is why people plate things with it.
Gun blue comes in two forms: rust blue and chemical blue.
Chrome doesn't rust, so that one's out.
Chrome is not otherwise chemically reactive, so that one's out too.
Chemical blue will discolor chrome plating somewhat, since home-bluing kits are based upon the deposition of copper, and copper will marginally affect chrome. But you will end up with an ugly mess, not a blued gun.
Best bet for a home-made finish that isn't chrome might be to "scratch" the chrome plating uniformly (and very carefully) with power-driven sandpaper. This will give the plating "tooth," so that paint can adhere to it.
Then paint it with an epoxy-based, spray-on paint that's made specifically for guns.
But this will not be a permanent solution to your problem. The paint will eventually wear off, and you'll be back to chrome, but now it'll be scratched-up chrome rather than smooth and shiny.
