John,
What is the interchange, if any, on this? Numrich has the flat levers (three step) for the 1006, 6946, and 4506. The 6946 one also fits the 669.
There are three sizes of levers, (actually, the length of the pin that goes through the frame) without regard to the thickness, color, or shape of the lever on the outside OR generation of pistol.
Size number one is for ALL of the single stack, 9mm pistols, full size or compact, standard or TSW, TDA, DAO, or frame decock.
Sometimes called the "small frame".
That would include: 39, 39-2, 439, 639, 3904, 3906, 3913, 3914, 3953, CS9, etc.
Size number two is for ALL of the double stack pistols, full size or compact, standard or TSW, TDA, DAO, or frame decock. Sometimes called the "medium frame".
That would include: 59, 459, 559, 659,469, 669, 5903, 5906, 6906, 6946, 4006, 4003, 6926, 5946, 4013TSW, etc.
Size number three is for ALL of the single stack, 40, 45, and 10mm pistols, full size or compact, standard or TSW, TDA, DAO, or frame decock.
Sometimes called the "large frame".
That would include: 645, 4506, 4516, 4505, 4513TSW, 1006, 1066, 4566, 1076, CS40/45, 4013 single stack, etc.
In summary, just remember:
1) Single stack 9.
2) Double stack 9/40.
3) Single stack 40, 45, 10.
The early compacts had "thinned" thumb pads.
The frame decocker slide stop levers are a little shorter on the thumb pad to help the shooter's thumb clear the decock lever.
That's it.
John
