Need help with a M&P Shield

GilaGila Posts: 43 Member
I want to replace the sights on my Shield.  I figure the factory sights were installed with a type of red Loctite, and to remove them I'll probably need to heat the Loctite to 500° F.  I know there are parts under the rear sight that may not be capable of handling that much heat.  Does anyone know of any tricks to remove the factory sights or if the Shield can handle that much heat?  I do have a quality tool to remove, adjust and install dovetail sights.

    Not familiar with the M&P Shield, but I seriously doubt they used red loctite, AND if I am wrong, and they did, I doubt they'd put something under them that would be damaged if they had to remove a sight for a factory repair

    I think I've seen it done on a Shield to put on night sights.  IIRC, a punch was used to knock out the old sight.

    On both of mine I stripped the slide and put it in the freezer for a while then took the sights off. They came off but were very stubborn. I used a strong sight pusher.

    I just called my local gunsmith.  He's done many...strip the slide, lock it in a soft jawed vise, drift from right to left.  Takes a little pounding with a soft punch.

    A sight pushed is best but a brass tap will easily work. The rear sight holds the stricker block in place IIRC so keep an eye out for it so you don't let it go flying.

    There’s no loctite from the factory, but the rear sight does hold a part or two in place, I can’t recall which.  Let an armorer or gunsmith do it.  They don’t charge much.

    I changed sights on 2 M&Ps, but neither was a Shield. Used a sight pusher, no Loctite was there. As LMLarsen said, the rear sight holds the striker block and spring in place.

    My Shields were way harder to push than my other 2 M&Ps. No idea why.

    Thanks for all of the help!  I prefer to do my own work, and I have a MGW sight tool.  I also know about the parts under the rear sight, but not what they are made of.  If I were a master gun smith, I'd use the punch and mallet method, but I"m not, and that's why I have the tool.  I'm going to try the freezer trick and see what happens.  BTW, this is not a money issue.  It's just that I live in the boondocks 60 miles from no where, and no longer know of a gun smith I can trust.

    Under the rear sight is the striker block (striker safety plunger), spring, and a small disc that rides on the bottom of the sight. It is more towards the right side of the slide.

    IIRC, the disc is plastic. It will fly, so go slowly

    I just want to thank everyone for the help.  The freezer trick worked just fine.
