looking mainly for a replacement blade with a v notch or peep instead of the factory square notch. the new model 8 shot blades are larger so they won't fit in slot. i was thinking someone on here may be able to suggest someone to contact to fabricate something or suggest ideas. it is a sweet little revolver. i just want to explore options and as these are discontinued and parts seem like hens teeth. front sight is pinned and i believe any changes i may want to make there would work with any sp101 sight options. many thanks for your input.
