Will they ever make a tail chop kit for the M1100?

no

they might. give it a little time. the m1100 has only been out for a short time now, so unless its the same as the 696 (actually looks like it should be...) you might have to wait a bit.

I called them 3 weeks ago on a Friday and he told me he was picking up an 1100 over the weekend to fit a tail chop.  He told me it would be ready shortly.  Call him and bug him.
