Sub par manufacturing tolerances - Meprolight Tru-Dot Night Sights for Ruger Handguns

Yes, the front sight has to be filed down to fit. The length is too long, and the keel underneath is too thick and deep. After very judicious filing I got it to fit flush. The tritium dot on the front sight seems underpwhelming; could be a little brighter or bigger. The rear adjustable sight will drop in, but after it is screwed in, three (3) deficiencies become apparent. The rear sight "jiggles" ever so slightly, so that when you touch it you feel it moving side to side. Second, the rear sight post is slightly longer than the original by 2mm; so there is a 2 mm gap from the buttress of the frame to the sight post. This makes the rear sight post more outstanding and susceptible to being whacked accidentally. Thirdly, lining up the "three dots" creates very fine mismatch, where if you line up the three dots, the top of the front center dot is actually lower than the top of the rear side sights.
Once you get the sight zeroed, yes, it does the job. It does glow in the dark, and so my GP100 is now "night ready". That being said, the company Meprolight had YEARS to read the reviews and make the necessary adjustments to their product, but they instead ignored it. They could've had an awesome product, rather than a mediocre one. Shame on them.
