If you are not aware, you can get the full target sight that comes on the Elite competition frame models for about 60 bucks; I imagine you slide probably has the same cuts and it would fit fine, but you could post pictures to be sure.
The Match has different slide/sight cuts than the other Elite series. Or at least the ones that I have owned did. Haven't looked at a Match made in the last 2 years, so I suppose it's possible they changed,
