Which way do you remove the front sight? Do you push it from the left to the right (the ejection port side) as shown on the exploded diagram from Brownells? I'm curious because I ordered some after market sights and their instructions state: "...knock out the front sight RIGHT to LEFT (as held in the shooter's hand aiming the pistol)."

Right to left. Left to right. Too confusing to this guy.



Knock it out to the ejection port side.

Thanks for the replies. I also checked with S&W, twice in fact. Both service techs said, yup, no change with S&W slide dovetail cut design, remove them from left to right (towards ejection port) and install them from right to left. The after market sight supplier provided incorrect instructions with their front sight. Well, it's even worse, they also sent the wrong sight. Oooops. The dovetail was oversize by about 0.020". Yo! No way that sucker was gonna fit the slide dovetail cut. They were very friendly on the phone, and said they are sending the correct sight. Also, both techs at S&W suggested pounding out the front sight rather than using my nifty P500 universal sight tool. They are that tight.

Yes, the front sight is in there pretty tight. Not as tight as Springfield's XD but pretty tight none the less. I very carefully used a steel punch with the slide locked into my bench vice between two thick pieces of doubled-up cardboard to pad it.



It took a few judicious blows with the hammer to get the front sight moving.

I wouldn't use a steel punch. Brass or copper would be preferable. A short piece of hard copper tubing (water pipe) will work if you don't have something better. Gouges from steel punch's are hard to polish out.

Was it a Dawson front sight? I went to install a Dawson fiber optic front sight the other day, and they had sent the wrong sight for it also.

When ordering from Dawson try to get one of the women to take the order. The guys working there seem to have their heads up....

So, here's the latest with the front sight story. Yes, it was Dawson Precision. Yes, they did replace the front sight. Yes the second front sight was EXACTLY the same, including the same wrong instructions. So I called again. Again, they told me they would replace the sight, except that the thin sight (0.100"wide) was out of stock and the replacement would have to be a wide one. Ok I said. But then a short while later, the gal called back and said that Dave said that their front sights for the S&W M&P pistol are made oversized and require fitting. She said they were willing to fit the sight if I'd send them the slide. Jeez, had it been in anyway stated that this was the case right at the beginning, all this mess could have been avoided. So, if you buy a Dawson Precision Fiber Optic front sight for your M&P pistol beware that: first, it needs to be fitted to the dovetail cut; and second, that the instructions are wrong concerning the direction to drift the sight out and back in again. Anyway, I fitted the sight, drifted it in and really like the sight picture. These sights were real quick to pick up during some dry fire drills I ran out in the yard. I won't be out to the range for a couple of days, but I'll add a postscript here with my feelings about the sights after I actually fire the gun.

Well my Dawson front and rear sights arrived yesterday. I just got done doing the trigger job and since the sight has to come off for the firing pin plunger, I went ahead and installed the new rear sight. Looks great, works great!! Now th [email protected]#$ing front sight will not come off. I used the little aluminum tool that they send with the sight, but it just deforms and pops off when I hit it hard. I had to grind it down to get good edges again. Same thing for round two, WTF! I sprayed some penetrating oil on it and will try again in the a.m. Any ideas or suggestion? Should I cut it out? If Dawson has trouble with thier front sight, should I send them the slide and let them do it? Little frustrated to say the least!!

How much did you have to take off the dovetail of the front sight? And I think the dovetail angle was wrong on the Dawson I was working with.

For coltman1985: the front sight is very tight. S&W must use some sort of hydraulic ram to jam them in there. Do a search and see what others have done to get theirs off. A solid, padded vice, good punches and a hammer. Drift it off from left to right....towards the extractor side of the slide.



YukonGlocker: The Dawson front sight was oversized by 0.019". That's a fair amount of material, but not insurmountable. The angle of the dovetail cuts were pretty much correct on both sides. Until I ground off 0.019" of course. Then they had to be re-dressed. I think it should be made clear up front that the front sight must be fitted, before you actually buy they sights, open up the packaging and ooops, now you have to hire a gunsmith. Or, as I did, do it yourself. Most folks do not have the time and/or the expertise (or is that the foolhardiness?!? plus extra $ for boo-boos!) to grind away on stuff themselves.

Thanks politegunner. I went a it "big time" with the hammer and punch. It finally broke loose, then it was easy tapping the rest of the way out. I filed the Dawson sight down (a lot) and re-dressed the edges, went in after 3-4 test fits. I can't believe how far off the Dawon front sight was!! Patience and a bigger hammer next time!!

I have the same problem with Dawson. The sight base is Wayyyyy off. I'm past my 30 days, so no refund. Not worth it to return it for another sight that doesn't fit.



Of course, I could spend shipping two ways, and pay them $25 to fit the sight to the slide (I don't have the tools to take that much off myself). Think I'll just buy a HiViz and be done with it....cheaper that way.



If they can't sell a sight that fits, why sell it in the first place??? Not happy with Dawson to say the least.

The usual way to fit an oversize sight is to file the bottom of the dovetail. It's much easier than trying to file the edges of the dovetail down. A good rule of thumb is to remove enough material so that the sight will go in about half way, by hand.



There is no way that you'll remove the factory sight on an M&P with a brass or aluminum punch. It's too tight. I use a vise with lead-lined jaws, a Starrett 3/16" punch, and a 12oz. ballpeen hammer. Once the factory sight is out, a brass punch is ideal for installing the new sight.

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.

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.

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.
