Welcome to the forum. Don't let the responses to your stipple job turn you away from the forum. Lots of good advice here. If the stippling works for you, that's all you can ask for.
Picture turned good on my PC started out really small but then opened full screen. Looks like it will work well but makes the gun butt ugly but then for SD I doubt the bad guy is wanting to admire it.
I'm not into stippling, but your rendition is very different from other stippling jobs I've seen.
The only drawback to stippling, as mentioned, is limiting who might be interested in buying it, should you tire of it and go to sell/trade it.
Now a pistol like a Kel-Tec (or P320?), where the grip is not part of the frame is different. When you go to sell it, simply buy a new (Kel-Tec) grip for $35 and you're back to original.
Oh... Why did you need to snap the picture in your car?
Does your Wife/GF/Mother/Significant Other not know you have the pistol?
Is it not allowed into the house/apt?
looks horrible but its fixable. lol. maybe if u went the same direction with the pattern and took alittle more time it would looked real nice.. no offense
