After several scratches and dings from punches in the past, I use a ground down, 1/4" wood chisel. I went to Home Depot and found one for 9$, ground off the cuttting edge, and smoothed out the edges with a Dremel. It has a nice handle and works great on the front and rear sights.

File on the sight not the dovetail. The first rule of gun smithing always file on the cheapest part.

If you file the dovetail it will now always be out of spec.

I meant the bottom of the dovetail on the front sight, not the dovetail cut in the slide.

Well.... I sure wish I saw this thread before "trying" to fit my DP front sight on my M&P. I installed the 10-8 like a piece of cake... the front... it just didn't work. I didn't grind the base down enough and when "pushing" it in with the punch it got mucked up. I had don idea you had to grind the base that much... I've never heard of sights requiring that much grinding. Live and learn.

Dawson Products

I had problems with Dawson also. If you have a part with them that does not fit and try to make it fit, you bought it. Period. Same think happened to me on a SVI magwell.



The gals at Dawson are usually pretty good but after my last Dawson fiasco, I try to buy somewhere else.

BiggDogg,



Your advice below worked like a charm. A big thank you.

I used an inexpensive sight pusher to remove the front sight on my M&P 22 Compact.... it came right off.

IK've got no complaints on Dawson sights. They're great sights. I assume anything I buy for my pistol will require some fitting unless I get it from Apex or S&W. Guess it is just my history with 1911 pistols that causes this perspective but I'm fine with stuff being a little oversized. Much easier to file down than to add metal :-).

Has anyone that had a front sight that was extremely hard to remove seen any signs of red Loctite on the sight bottom/slide dovetail?

If so, use of a little heat prior to attempting the FS removal may make things go easier.

I've removed several M&P rear sights, but have had no reason to remove a FS.

The rear sights I've removed all had red Loctite on the Allen screw. Heating that first with a soldering iron made the screw removal easy.

This^. When I removed the rear sight on my M&P Pro 9 to install the Apex CAEK, I couldn't budge the allen screw. I remembered a forum member (might have been you, Rick) recommending using a soldering iron to heat the screw to loosen the loctite. Once that was done, the screw came right out. Finding tips like that is part of what makes this forum great!

The front sight on my STI Trojan was a different story. I needed to remove the original sight to install a Dawson F.O. front sight. I watched the video in which Dave Dawson lightly taps out a front sight on a Trojan. Thinking how easy that looked, I started with a small hammer and the aluminum punch that comes with the sight. When that didn't work, I moved to a bigger hammer and a brass punch. After bending my brass punch, I ended up getting it out with a steel punch and a 2 lb. hand sledge. When the sight finally broke free, I could hear it ricochet off the walls, and it's still resides somewhere in my garage. Not as easy as Dave made it look in the video.

I have the cheap sight pushed that I bought from eBay. I spray the dovetail with wd40 or use gun oil and they come off in seconds. My shield took a few minutes though.

You're supposed to file down the front of the dovetail on the sight, not the bottom of the sight from Dawson.

Almost all new sights need to be fitted. I recommend that you get them to go in by hand at least a quarter to a third of the way by hand. Yes, S&W rams them in with a hydraulic press. Saves them the expense of properly fitting them. If you think the M&P sights are tight, try getting them off one of the older 3rd generation Smiths. Frequently the old Novak sights are corroded on the bottom in addition to being tight to start with.

My 'smith had to mill the front sight off of my Pro Core. He works on lot of M&Ps and says they can be very difficult to take off but he had never had to resort to milling before.

Ed, welcome to the forum. I've got one of your sight pushers, and would happily recommend it to anyone looking to purchase one.
