question about sight interchangability

I've been wanting to put some Ameriglo hackathorn sights on my full size M&P9 and I have a credit with OpticsPlanet that will cover them, but it seems like the only M&P hackathorn sights they carry are for the Shield.

Would Shield sights work on a full size M&P? Any POI shift or problems with the fit?

Most everything in the way of sights is different on the Shield compared to the full size. Without actually measuring them I would almost bet they aren't interchangeable.

They may well fit.

HiViz sights that I have a bunch of for full size M&P's are listed as interchangeable with Shield.

I saw posts where people were putting TruGlo sights for the full size M&P on their Shield and just had a little overhang of the rear sight, so that's why I thought it would work

10-8 M&P rear sights

First it says:
'The rear sight fits all calibers and all sizes of the M&P series,'

Then right under that it says:
'**These sights are too wide to correctly fit the Shield. We have dedicated sights for the Shield.'

S&W M&P Rear Sight - 10-8 Performance Store

So that implies that sights for the Shield might be narrow and while they might fit, they might look funny/odd on a full size.

I would shy away from those LITEWAVE sites, dang fiber optics falls right out of them. But if you must have them, super glue the tube in.

Everyone's experience is different.

I must have 8 pistols with the Lightwave style with tens of thousands of rounds fired and have never experienced the fiber optic element being displaced from the sight. When properly installed it requires a tool to remove the fiber optic element !

Not only is gluing the fiber optic element unnecessary, it would destroy the fiber clarity and thus its transmission of light, as well as prohibiting one of its features which is changing out new colors and new tubes when they do fade due to use from muzzle debris etc.

I guess i should have explained my statement more clearly... one dot of super glue at the front leading edge of the tube will keep the optic from pulling out. Tip the sight vertical, one tiny drop will fix it. This dosent mean cover the whole fiber optic with glue, which WOULD ruin the light transmission thru the fiber optic.

Consider yourself lucky... but, believe me, there ARE complaints right on this very forum, of LITEWAVE fiber optics falling out of the PC guns. One of my own PC fiber optics fell out of the sight. Tiny dot of super glue to the very tip of the sight, fixed the problem. And did NOT effect how clear the sight is after gluing it in place.

Just have to work smarter, not harder... common sense shall we say...?


EDIT ADDED:
And if you feel the need to change out the fiber optic, even if a tiny dot of glue was added, they pop right out with use of a small punch.
How do i know this..???... i`ve already done it. Slight amount of pressure, they come right out. Nothing ruined, everything is all re-usable.
