Hey! Oh, so THAT'S how it is now. Cannot even mention my name.
Sure enough, works like a charm. When I did it, the 1400 was and probably is the only gun in the retired Crosman lineup that uses such a long stroke. Modern examples of long stroke guns are the 2200/2100 based tube variants.
Use a long steel breech, the barrel floats the entire length. Simple modfication to the front plug. Few other modifications to do that really are not that invasive. A "kitchen table" project if it ad to be. A steady hand goes a long way when using hand tools.
Wish I still had pictures of the build process and final result... Actually, there are a few left.
Here is the 2260 trigger pack mounted up:
This shows the shot of the internals through the slot (edit: not internals, but the sear):
The rear of the tube will need to be trimmed down so the 1377 end plug works. You can use the 1377 front plug/barrel band if you trim the front down too.
