Stippling is as time consuming as checkering. Has to be done correctly to look good too. It is not hard to do though. Uses a nail or a special tool(Brownell's sells 'em. Cheap, they ain't though. $25.99US each. Easily made with bar stock and a file.) and lots and lots and lots of patience.
However, these guys, in B.C., do it. $100 per handgun. $150 per rifle. Add the W's .milsig.ca/contact_us
Best to call your local shops and ask.
