New sight love for the old 617!



Log in to see fewer ads
Best $65 I ever spent on a gun! This 617 was shooting a little high with HV ammo in close at 12 yds so I used this as an excuse to fix it right,. After some research, I added a (.1"x.215") Dawson Precession front Fiber Optic and a new S&W ( .165") rear blade with white outline. ( Factory sights are .175" and .146" respectively BTW). The sight picture is amazing and the gun shoots POA with any ammo tried.

Nice, I went with an SDM front sight .125 x .250 and a .196 rear blade I opened up to .150.

Much better for my old eyes.

Nice looking setup! I have the Hi-Viz front sight on mine. I shoot it well enough but prefer a thinner front sight. Right now, I have an optic mounted so it doesn't matter.

The high viz is a nice sight. Very robust. Unfortunately, they only make them in two heights ( .175 and .250) and I needed something in-between to cure my POA vs POA issue. I have a 6" 617 that I'll resight at some point but also have a Weigand base and a 3-6x32 Bushnell trophy ready to go on it so that project is on hold.

Looks good. What was involved in installing the front sight? Any issues to watch out for?

Good job. I replaced my front with a fiber optic from Dawson's as well. I put an LPA rear sight on my 617.

You have to drive out the pin, then drill the new front sight. I let a gunsmith do mine.

Yes, I actually contacted a local smith to do the work but he was booked out for months. So after some online research, I decided it didn't look all that complicated. I used a dulled sewing needle for the punch and the pin popped right out. I then put the old sight (still in the gun) into a vise jaw and tapped the barrel away from it with a plastic hammer. The sight fell right out. The new sight took no fitting. I just held it in place and used a #54 drill bit to alternately drill the pin hole in place from both sides. The existing holes in the barrel act as a guide so it's hard to really mess up. I switched side to side maybe 4-5 times to each side only drilling a 1/32" or so at a time. The hole came smooth and true when it met in the middle of the piece. From there, I just tapped the old pin back in and I was done. It took more time to get up the nerve than to do the work in all honesty. I'm going to do my other 617 next.

BTW, Breaking the screw in the rear sight in order to replace it was actually the most daunting part of the entire job!

S&W rear sight blades come in three sizes. I always use the biggest .196.

It gives me a better sight picture.

I ordered a DP front sight for my 4" 617 (0.1 W x 0.18 T) that will give me adjustability with the stock 0.126 rear sight. Right now the rear is all the way down with the stock 0.17 front. I also like the thinner front sight so I can "aim small, hit small".

Looks good. You will like the Dawson Precision sight. I put one on my 617 and it makes a big difference.

I used an LPA rear sight.
