After coming home from the qualifying range today (CHL license), I realized I hadn't been able to see the rear sights well. Noob that I am discovered the rear sight it a dead tritium sight from MM. Two little yellow dots are duller'n dove shlt. Front sight appears to be an original, painted white dot. I'm not really flush with cash right now, so what do you recommend? Go with a stock rear or can the MMC sights be refurb'ed? I'll be practicing in the coming weeks and carrying it when my license gets here. Or should I just learn to point and shoot this thing "as is"? I appreciate your help with this.
