What you are requesting does not exist.
The closest was the old Eagle Secret Service, but they extended the length of those. You can request Badger make you grips without finger grooves, which slims up the profile, but not by a lot, they extend past the frame.
You can talk to Craig Spegel, and he'll sell you a pair, they'll still extend past the bottom of the grip frame. You can shorten them yourself, but Craig won't do it. Craig will also explain
why there aren't the grips you seek.
But to save you a phone call - It's because Colt historically had very bad quality control over the frame dimensions of D-Frames, particularly by the late 1960s. I've had a half-dozen different D-Frames in my life, none of them -
none ever wore the same pair of grips the same way. Each grip needs to be "fitted" to a specific gun, because of dimensional differences. Differences include, several thousands of an inch different in frame thickness, in front-to-back width, and in the shape and amount of squaring of the square butt.
The reason Pachys are so popular is because they basically cover that mess and allow you to get on with your life.
If you want the lowest profile grip possible for a short D-Frame - these:
https://tenring.com/other-stuff-for-...t-agent-grips/ are the grips you seek, paired with a Tyler T-Grip. This gives you the absolute lowest profile, ever. It's also a tough combination to construct, because flush short-frame grips are exceedingly rare to find.
You can cut up your own - of course - NC Ordnance makes all kinds of ones out of plastic -
https://gungrip.com/coltdoubleaction...ergrips-3.aspx that would be easy to cut down. Altamont makes wood ones:
https://www.altamontco.com/pistol-grips/colt/D-Frame/ - I'd do the Altamonts and cut them with a band saw while attached to the gun. Than taper the base with a Dreme sanding drum them like those shown in the Ten-Ring link above. This will make them flush, but taper so the flat doesn't jab into your palm.
Tyler T-Grip Size 5 -
https://www.t-grips.com/ is what you will need. It will need about 1/4" chopped off the bottom to fit well. Dremel them smooth with a stone wheel or sanding drum.
Once you have the panels shortened to your liking, I suggest taking a Dremel and rounding the butt down to match the contour of the grip. If I had to guess, I'd say you have a 50-50 change of wood panels being too small for the square butt of the frame. You may also need to carefully file away the T-Guard where it contacts the upper part of the frame of grip strap. Not also, but sometimes, there are clearance issues with the T-Grip not fitting firmly to the frame. First time you go to shoot it, it will move and can pinch the shit out of you (ask me how I know...
).
Hmm, that's 3-times I've said to Dremel this job up. So, you should probably phrase the question as, "Are there any Colt D-Frame grips that don't require me to Dremel them or the gun to work?" - Answer: "Yes, Pachmayrs."
