I am looking for an orange fiber front sight to go on a Sig .22 rimfire conversion slide. The existing rear sight is adjustable for both elevation and windage so I am planning on keeping it. The front sight needs to be about o.280" tall and have a base that will fit the existing front dovetail. I have a F/R setup like this on another rimfire pistol and like it very much. All help and suggestions appreciated.By the way, the conversion slide is being used on a P220 receiver.

Not sure of your exact model, but I would start with Dawson Precision to see what they offer.
