Stippling your firearms and accessories is a great way to get a great grip on your firearms to suit your applications. With a little bit of practice and patience a gun owner can accomplish a fine job on his/her firearm without having to overnight mail it to gunsmith, pay $80-300, and get it shipped back home. With that said, there are some gunsmiths out there that do outstanding work. If you are willing to pay for it, that may be your best option.
As long as the political climate remain roughly the same you can get your gun to any of the stippling experts around the country. If you want to save some hard earned cash, or the political climate changes and one cannot ship firearms, investing some money into a stippling kit and tips, and some time into practicing your techniques and watching some videos for ideas may be a good investment.
OTDefense offers multiple tips for many options in design and felt texture. All of our tips are 8-32 threads and fit in common wood burners, and some soldering irons.

Common sense - take your time, practice on some old A2 grips, magazine floor plates, old clinton era 10 round Glock 17 mags (unless you live in a state that requires you keep them), some of the practice material we sell here etc. This will give you familiarity with the tool/tips, and enable you to recognize some important things (outlined below). Then and only then should you move on to your firearm. If in doubt, take it to an experienced gunsmith.
Time, heat, and pressure. This is what controls the process.
Time: More or less time is required for some materials then others.
Heat: More heat is more suitable for some materials then others. I recommend a 25watt woodburner for most users and most jobs. The burn just under 1000*F generally. A 40 watt unit would burn so much faster that it would require less time and pressure. Why not use a 40 watt then? Because it also makes it easier to mess things up. The tips are designed to increase productivity by covering more surface area rather then using and ultra hot tool.
Pressure: Pressure controls the flow of material as you melt it. Realize that is what you are doing, melting the gun's material, allowing it to take the shape of the tip you are using. Keep in mind different gun frames will 'melt' differently. Glocks are harder material then XD's, M&P's removable backstraps are super soft and require a gentle touch. Don't practice on a Pmag (one of the hardest things on the market) and then jump into your Glock and expect the same results while utilizing the same time/pressure.
Some important notes:
Most colored gun frames will not retain the factory color, as the waffle tips will leave a small amount of material on the tip, resulting in your frame having a black tint to it in spots. You can mitigate this by keeping the tip VERY clean with a brass/copper wire brush, but do not expect it to come out the exact same FDE tan, green or gray that you started with.
