I have an M&P 9 2.0 Metal that I would like to replace the sights on with fiber optic sights. I purchased an LPA adjustable f/o sight set that was listed as fitting a M&P 9 2.0 (but did not specify the Metal model), which is how I learned that some models have a wider rear sight dovetail set about 1/2" forward ov the back of the slide, and some have a narrower dovetail set only about 1/8" forward of the rear of the slide.

I was able to return the incorrect sights but am hesitant to repeat the trial-and-error process. Can anyone suggest how to get sights that fit, or recommend a particular set that you have successfully installed?

Thanks in advance for any helpful advice . . .
