Default M&P sights?

OK, have pretty successfully confused myself so far over this. The S&W site is singularly unhelpful on the subject, thought I'd confirm with the vast repository of FTF knowledge here.

I got the following info this morning via email from the guy who imports MPs in Aust -

Yes, the M&P PRO series has a fixed rear sight as does the standard M&P9L.

First off, most of the details re handloading go way over my head, fascinating though they are however for some weird reason I had been under the impression that the 9L had adjustable sights...but apparently not. My club's captain had been fairly particular in saying last week that I should get a gun with adjustable rears, and reading the above email, I can now see why. Not likely to be reloading in the immediate future.


So...any point considering aftermarket adjustables in these circumstances? I have about a month to wait now before the importer gets back from a trip to Melbourne. Time to decide...time to amass all the other stuff I need...learn how to clean the damn thing, etc

The M&P 9L appears to have the same sight set up as the standard pistols (albeit with out Tritium inserts).

Remember, the "fixed" sights are actually adjustable. Drift adjustable for windage. The elevation is adjustable by using different front sights. "Adjustable" sights are simply "click adjustable" using a screwdriver. Some people prefer such sights for range work. "Fixed sights" are just as good once adjusted to the ammo.

Being in Australia, there is little chance you will be using this as a concealed carry piece so the snagging of "click adjustable" sights is not an issue.

Some "old school" handgunners insist on click adjustable sights, just because their game is bullseye. Drilling 5 shot ragged holes in the dead center of a target is fun but can become very boring. Modern "combat" shooting (IPSC/IDPA etc) calls for fast shots into the center area. Fixed sights are all most people will ever need.

Many thanks for that detailed explanation robo, much appreciated. I might be a bit of a slow learner here but its finally making sense. Finally, heh.

Checked out a 2-day competition held last weekend which hosted 5 of the best shooters in the country, and I noticed that a majority had both fibre optic & adjustable sights. However, one guy I asked was using a 9L with stock fixed rear sights, just installed a thinner aftermarket front filed down to achieve POI/POA. He shot with it in a US comp earlier this year to good effect. Gave me 1 mag to put through it after the comp had ended; was very impressed with its ability to return to sight picture...I think the lower bore axis helps a lot.

Also he mentioned any aftermarket sights would have to be milled to fit the MP, as messing with the slide is illegal in Production.


So...looks like stock sights will do. Just have to decide between the two now - If I can try out someone's fibre-sighted gun this weekend at the club comp that might help
