S391 Posted April 7, 2011 Share Posted April 7, 2011 Can anyone tell me the height of the stock front sight on a S&W 625 JM? I'm looking to buy a new FO front sight and I want to make sure I get the correct size. Thanks in advance. Link to comment Share on other sites More sharing options...
GlockCanMan Posted April 7, 2011 Share Posted April 7, 2011 (edited) Look at the front of your barrel and see if you have a hole under the front sight...If you do you should be able to slip it straight back and lift your sight out. You can buy a replacement from SDM It will be the .300 sight. Edited April 7, 2011 by GlockCanMan Link to comment Share on other sites More sharing options...

Toolguy Posted April 7, 2011 Share Posted April 7, 2011 Unless the rear sight is really set high to be sighted in, a .250 will be too low to get sighted in with. Link to comment Share on other sites More sharing options...
S391 Posted April 7, 2011 Author Share Posted April 7, 2011 I always get this messed up..... if I'm shooting low do I want to add a taller front sight or a lower front sight? Link to comment Share on other sites More sharing options...
Toolguy Posted April 7, 2011 Share Posted April 7, 2011 Lower FS for shooting low, higher FS for shooting high. The rear sight on a S&W revo only has about .040 adjustment before it's at the top of the screw. Ideally, you want it about .010 to .025 up off the step on the frame.

Forrest Halley Posted April 7, 2011 Share Posted April 7, 2011 My JM came with a .250 gold bead patridge. It wasn't a fan of a .209 hiviz I put in it, but it never minded the .250 with factory ball and whatever reload guestimations I put through it. XS tritiums are like .275 and my JM is currently wearing one. .300 sounds high to me. Link to comment Share on other sites More sharing options...
Toolguy Posted April 7, 2011 Share Posted April 7, 2011 A lot of it depends on what loads you shoot and how tight you grip the gun. Link to comment Share on other sites More sharing options...
Forrest Halley Posted April 8, 2011 Share Posted April 8, 2011 Anybody know who makes a serrated black patridge .250 classic/dx sight? Link to comment Share on other sites More sharing options...
mikey357 Posted April 8, 2011 Share Posted April 8, 2011 Anybody know who makes a serrated black patridge .250 classic/dx sight? Don't know about SERRATED, but Jack Weigand makes a .250 Patridge Front Sight that fits the Classic/DX Sight Base...I think Midway USA sells 'em...also check w/Toolguy, he may make 'em too...HTH....mikey357 Link to comment Share on other sites More sharing options...

No.343 Posted April 8, 2011 Share Posted April 8, 2011 If you are shooting low then you need to lower your front sight. This will raise your point of impact. Link to comment Share on other sites More sharing options...
Toolguy Posted April 8, 2011 Share Posted April 8, 2011 (edited) No.343 has it right. For an additional $5.00 I can make a serrated black F/S. That would be $45 + $5 shipping. I will add that to my vendor forum. I make both classic and pin on. Edited April 8, 2011 by Toolguy Link to comment Share on other sites More sharing options...
S391 Posted April 11, 2011 Author Share Posted April 11, 2011 I just got an email response from Smith & Wesson and the stock front sight on a 625JM is .243.... in case anyone wanted to know. Link to comment Share on other sites More sharing options...
Matt Griffin Posted April 11, 2011 Share Posted April 11, 2011 An easier way to think about it: The bullet moves WITH the rear sight and AGAINST the front sight. So if you want the bullet to move up, either move your rear sight up or your front sight down. Same for windage. Matt Link to comment Share on other sites More sharing options...

I spent 15 years shooting sporting clays so I never had to worry about sights....... Link to comment Share on other sites More sharing options...
