Hi Gerben, probably should! But, setting here thinking, I have been toying around with making the slider button and indexing point out of tool steel, custom fit for 100% ingagement, and heat treat it... hoping, that the depth of the indexing tooth goes deep enough into the sight ladder, even if slightly worn, to hold it securely! Got nothing to lose.....
..... best to all, til.....lat'r.....GT
