You look like youre well on your way.
Dont get discouraged if it doesnt come out to your liking the first time either. Unless you really get medieval on it, and burn through the frame or something, you can usually redo what you dont like and still get a good result.
Ive seen all sorts of different jobs looking around the web when I first started. Some guys do some unbelievable work. Some really cool stuff.
Im more into basic and functional.
Ive seen some people use what looks like a waffle iron tip, and all sorts of other tips. Whats cool is, you can pretty much alter any of them to fit your needs with a file. Like I said earlier, I filed the pointed soldering tip that came with mine, to a very fine point. You need very little pressure to get some depth, and it looks more like velvet when youre done. Takes a bit longer to do though.
Like you, I started filling in the factory borders that had some finish in them. I think youll find, youll get better results from a shooting/grip standpoint if you stipple the whole grip. Compared to the innertubes, tapes, and stick ons, stippling allows you to have seamless full coverage, right where you need it.
You may want to watch doing the underside of the beavertail. I do mine, but some people complain about it being a bit too much. My hands are pretty rough (and the main reason I stipple) and I prefer the grip. It does work as an exfoliant though and keeps those rough spots evened out. And I dont have to have the Asian girl at the Smile Salon to do it.
One thing to consider with the overly aggressive patterns are your clothes, and possibly even your skin. Ive heard some complain that their clothes take a beating and get torn up. I havent had that issue, but I can see how it could happen. Probably best to not use it with your best Leisure Suit.
I did run into a little "discomfort" wearing my 26 in an ankle holster "once". My sock didnt come up high enough, and the grip was rubbing on my leg. Got old real quick. Simple fix, better socks, and no problem after.
Once you get "everything" done, post them ALL up! Dont forget to do your Glock knives too. They really benefit from it.
