So I bought a pair of fiber optic rear sights for my M&P Compact. One thing I'm wondering though when I put the new ones in is there any adjustment that I need to make for accuracy? Or is there really only one place they can be? I've never changed the sights on a gun before so I am curious if I'm going to screw up my accuracy if I don't get them back in the exact same spot that the factory ones were in.

You will want it dead center. Be very careful removing the rear sight on an M&P because it has plunger with a spring underneath the rear sight and it will fly across the room.

All sight adjustments are done on the front sight, keep that in mind.

Calipers are your friend.

Dawson Precision has instructions and videos for installing their sights. Perhaps your manufacturer has similar aids. https://dawsonprecision.com/instructions-for-dp-parts/

I use the Dawson Precision fiber optice front and charger rear. The rear sight is solid and black with a forward slanting front face to aid in one-handed manipulation of the slide. I took a look at the instructions and promptly ordered the sights through my local trainer who also installed the sights. $94 total.

A friend of mine has done a lot of gun smithing over the years, he happened to have a B&J machine p500 sight tool. Made it exceptionally easy, even keeping the little spring and plunger in place till I was ready to put the new sights on. I used a little micro ruler to try and get the center of the sight dead center the top of slide.
