This came up at Landrun and have not gotten an answer yet from the TGs.
The cavalry officers model model holster of 1912 had a strap, not a string to tie the holster down. Mine had one as well and I was told during the warm up match that the strap was not allowed as it was not of traditional design. I removed it and shot the match without the tie down.
What are your ideas or thoughts? Allowed or not?
