Does Meprolight offer contrasting color night sights (yellow or orange rear, green front) for the P30SK (or P30/HK45C)? On the Meprolight website I only see contrasting color sights for the USP, the P30 sights are green/green only. If not, can anyone comment on Trijicon Bright & Tough contrasting color sights on a P30SK (or P30/HK45C)? Any recommendations on yellow vs. orange rear sights? Thanks.
