Yes that's very thorough especially with the introduction dates of the changes. and photos.
A few things are left out:
1. All the casting code number changes are not included. The XR3-RED Size new models will be found with:
Earliest production = KXR-3,
Next = KXR-3 with a separate N,
Late = K (in circle) XRN-3,
More current = no casting #
2. The New Vaquero has the new XR3 size grip frame EXCEPT the NV .44 Mag does not, it has the new XR3-RED size. The Flattop Blackhawk 44 Mag however does have the XR3 size grip frame.
3. The XR3 size is only 7/16" thick while all other Ryger grip frames are 1/2".
4. Terms like "smaller" and "standard" cylinder frame are confusing especially to those not as familiar with Ruger frame sizes.
Ruger has:
-- a small frame (.22 and .32 SS, Super SS, Wrangler),
-- mid size frame OM .357, NM flattop Blackhawks, and New Vaqueros (except 44 mag is the large frame in both models),
-- large frame (all other Blackhawks and Super BH)
-- extra long frames (357 maximum, etc.)
