Nice 629 8 3/8" DX! I've been looking for one just like yours recently since I really like the 8 3/8 BBL. I agree with you. This particular model needs a square butt. The first thing I'd do would be to put on a pair of conversion target grips on that round butt.
I bought from Vitoonmakers before and did not know they offer conversion target stocks that look so close to the original S&W targets. Looks very nice on your gun. What's the name of the the VItton model grips like yours? I'll be looking for them on eBay.

Previous owner discarded test target. It wasn't in the box nor was any of the paperworkSweet dash five DX
That’s a great snag! Congratulations
Very interested in seeing a photo of your test target, if it was included in the box
The flat side combats are very nice, I’m in total agreement of too much gun for a round butt
It came with a comfy set of rubber grips which I prefer on shooters
