Are they the same weight frame?

[POSSIBLEXS]

The model 1006 and model 1066 look very similar. What I am trying to determine is this: except for the length to accommodate the barrel which is 3/4 longer, are the frames of these two models the same? I am looking at 10mm guns. The 1006 has achieved quite a reputation for being able to handle this cartridge. I am assuming the 1066 would have this same benefit, if the frames were the same weight. Do any of you who are more experienced with these models, have an answer to my question?

As I recall, they are the same length. Now, the 4516 frame is shorter in both length and frame height.

the dustcovers on the 4516, 1006/4506, and 1066/1076/4566 frames are all the same length

only difference on the 4516 is the grip length
