Yes I have and it was returned to the Agent. Be very careful, it is not a panacea, you still have to be able to shoot properly.
The design and workmanship is superb, much superior to PFS .It is expensive and does not have a recoil reducer. If you really need one such as having a hand disability, investigate, otherwise think twice.

Reason....Nill do not make a true lefthand stock !!!...despite the brochure showing a lefthand illustration. If you stand square-on at the address you may find you do not have enough cast.
