For you guys that put a night sight on the SP101 I need some advice. I took the old sight out drilled the new night sight but I'm having trouble getting the sight pin back in. The night sight holes are in perfect alignment with the sight pin holes but the pin is super tight going in. I'm afraid if I pound on it I will break or deform the pin. Any advice on getting it in? It was a huge pain getting it out so I ordered a brand new sight pin.
