NMBOpen Posted April 11, 2008 Share Posted April 11, 2008 I have a 625-4 Model of 1989 5" that has reached the extreme of elevation adjust, but needs to go a little further to put POI on top of front blade. Rear blade is at max height, and had popped out of threads. Looking for suggestions. Link to comment Share on other sites More sharing options...
Revopop Posted April 11, 2008 Share Posted April 11, 2008 I'm a total neophyte in this area, but I would guess that you may want to get a different rear sight. My Model of 1989 has a Millet rear and an SDM fiber optic front. I like it a lot more than a standard rear blade, as the sight picture is a little more like a Bomar rear. People on the forum also speak highly of the LPA rear sight, though I have no personal experience with it. Another option may be to file down the front sight. Others may be able to comment on whether or not you've got a problem other than the sights and the sights are just a symptom of an underlying issue. Good luck!

Matt Cheely Posted April 11, 2008 Share Posted April 11, 2008 Black front sight? Out comes the milling machine, or a file would work. Link to comment Share on other sites More sharing options...
mark dye Posted April 11, 2008 Share Posted April 11, 2008 You have a couple of obvious options: shorten your front blade or have somebody install a shorter one. The other is to install a taller rear sight...either by replacing the blade in your sight or buying an aftermarket one. The Bowen Classic Arms S&W sight is a good one, and a tall rear blade is available. Mark Dye Link to comment Share on other sites More sharing options...
Tom E Posted April 11, 2008 Share Posted April 11, 2008 Change the rear blade. A .160 rear usually works fine with a .278 or .300 front. Link to comment Share on other sites More sharing options...
Carmoney Posted April 11, 2008 Share Posted April 11, 2008 Please don't be offended by this, but before doing anything to your sights, have you made absolutely sure you're not yanking your shots low?? Have you benched the gun, or had an experienced revolver shooter give it a try? It's just that I've never seen a factory 625 that couldn't be properly dialed in.....

This would have been my suggestion. It also has the benefit of being cheap to try. Link to comment Share on other sites More sharing options...

This would have been my suggestion. It also has the benefit of being cheap to try. +1 to the above. Also cheap (if it is in fact a gun problem) is to take the gun to the range with your ammo and a flat file. Set the rear sight about where you want it and file down the front sight (shoot three rounds, check POI, five swipes with the file, repeat as necessary). Finish it up with cold blue.

NMBOpen Posted April 11, 2008 Author Share Posted April 11, 2008 I am using a laser bore sighter (SiteLite) in the same manner that I use it (successfully) to set up my 1911/2011 Limited and Open guns. Even with the rear sight all the way up, the top of the blade is more than halfway down the front sight before the laser appears on top of the front sight. Seems a shorter front sight, possibly with fiber optic would be the simplest solution if I need to change sights. Link to comment Share on other sites More sharing options...
Round_Gun_Shooter Posted April 11, 2008 Share Posted April 11, 2008 I am using a laser bore sighter (SiteLite) in the same manner that I use it (successfully) to set up my 1911/2011 Limited and Open guns. Even with the rear sight all the way up, the top of the blade is more than halfway down the front sight before the laser appears on top of the front sight. Seems a shorter front sight, possibly with fiber optic would be the simplest solution if I need to change sights. I have a bore sighter and have never had good luck with it on a revolver. YMMV SDM makes a .250 and a .300 front sight. Weigand has .200, .250. and .300 in plain black Patridge EGW Fiber optic is .295 All that said, I would check the rear blade and change it as needed. If I were going that route, I would buy the LPA rear sight (which is what I did) from Top Gun Supply who has the best price I have found at $59.95 but they are out of stock right now. Speed Shooters Specialties is a little more money but great to deal with. Then put a .300 fiber optic on the front and you will be good to go.

10mmdave Posted April 11, 2008 Share Posted April 11, 2008 What load recipe are you shooting ?? (PF, bullet weight, velocity ?) Can you measure the sights you have ?? Not knowing what pf load your shooting make's it a bit tough. I have a 627 that I have to replace the rear sight on to shoot static steel loads or knock down steel loads (30 pf difference) What R_G_S says for replacement sights is good info too.

Intel6 Posted April 11, 2008 Share Posted April 11, 2008 I had to trim down the front blade on my 3" 625 so I could shoot some lighter lead bullets that I cast. Some day I will just replace it with the proper height blade. Neal in AZ Link to comment Share on other sites More sharing options...

Tom E Posted April 11, 2008 Share Posted April 11, 2008 (edited) Your laser bore sighter is useless for elevation. Shoot the gun rested to compare you point of impact with shooting off hand. The .160 rear blade works well and is tall enough to allow deepening the notch along with widening it. Edited April 11, 2008 by Tom E Link to comment Share on other sites More sharing options...
Toolguy Posted April 19, 2008 Share Posted April 19, 2008 (edited) There are new fiber optic sights for S&W revolver at Cylinder and Slide. They have front f/o pin-on and Classic in .250 and .300 tall, patridge or improved ramp and f/o rear .160 tall that goes in place of the original blade. I have them on 5 guns and really like them. This is the 625 with a .300 front. You can see in the pic there is about 1/2 of the adjustment left to go up or down. One more option. Best Regards - Toolguy Edited to remove quoted post.

Protocall Design Posted October 3, 2018 Share Posted October 3, 2018 I know this is an old topic, but we recently got a request for an Improved Ramp fiber optic front sight. This is just a post to let you guys know we no longer carry Improved Ramp sights. Link to comment Share on other sites More sharing options...
