This is nearly the same as a Colt Lightning grip, and may even work fine on some clones. Send a tracing to see. I don't have any way to tell by the model or brand, as even the same model can vary with different production runs. Most of the Single Six frames made now use a simple rounded curve shape, rather than the more complex set of "Lightning" curves. Be certain to compare appearance and measurements if you don't send a tracing.
(Yes, you can order it in any color. Even pink!)
Here are the dimensions:
Over-all height (B) = 3.0 inches
Front edge length (A) = 0.85 inches
Width across the top (C) = 1.3 inches
Middle of front edge straight back to rear = 1.45 inches
Narrow part of the "neck" = 1.0 inch
Screw hole center distance from top edge (straight down) = 1.35 inch
Screw hole center from rear edge (horizontal line) = 0.5 inch
Stock items (medallions, screws, specials) usually ship within 10 days.
I can't promise a specific ship date, as it will vary with circumstances. Depending on the time of year and number of orders pending, average time to finish a grip order is 30 to 90 days. That's average, not a quote. They are all individually made to your specific order.
If you can't wait, please don't order! I'm working as fast as possible.
