I don't like nickeled guns and would go for the one on the right. It's certainly unique but more importantly, the pencil barrel will take proper advantage of the tiny frame and show just how nicely the Is carried. The heavy barrel might as well be on a J.
As for grips, a BK adapter can be sanded down to fit an I-frame and the ivory colored one would complete the gun after coloring the sights. And most-all J-frame stock panels can be shortened to fit an I. I've even got a buddy who shortened a set of Barami Hip-Grips to fit a shorter barreled I-frame and epoxy filled the void at the bottom. It made for a super handy little pistol.
We also all need a barbeque gun and I-frames are absolutely adorable.
