    Hello, all!

    Two weeks ago, I purchased a 640 for my wife to carry. I seriously love that little revolver, and see one like it in my personal future! The biggest complaint that either of us has on it is the front sight. It's got a black ramp on it, and it's just difficult to sight in quickly. Have any of you had a problem like this, and what would you suggest for an alternative? Thanks!

    Since the 640 has a pinned front sight, it is easily replaceable.

    Besides my 640, I also own an M&P 340--and I really like the small-sized tritium front sight on that one.

    Call S&W support.

    They will know what sights will fit the 640, but they may get their undies in a bundle looking for the correct height--e.g., to get it to shoot to the correct POA.

    Unless you have your typical SD ammo sorted out, just tell them it's for a standard 158-gr. load; I've found many SD rounds have been tweaked to match that POA.

    A tritium ramp would be sweet on this one! I believe that I will call S&W and see what they suggest. Thanks, Jim!

    Ditto on the XS sights, can't go wrong with either standard dot or big dot although the standard dot seems to be more proportional with rear sight slot on the M640.

    I agree with the XS big dot.

    The gunsmith at Gander Mountain put the sight on for me. I put the ghost ring on my Marlin 1894 myself, but the guys at XS told me that the pin is not consistently placed on the 640, so they ship it undrilled and they recommended that I have a professional install it.

    I would also encourage you to get the Crimson Trace laser grips for it. I like the LG-305 and have it on all my snubbies (640, 642 and 60). http://www.crimsontrace.com/Home/Products/SmithWesson/LG305/tabid/233/Default.aspx?id=533
    It is a little bigger and allows a better grip. But others like the smaller one.

    Either way the laser and Big Dot make a good combination that will serve well in all light conditions.

    She says she wants a gold bead. I think that would work well.

    Talk her out of it. I know that sounds a bit arrogant, but there are far better options available. I cannot see any reason to give up the option of having tritium for low light use. Gold bead sights may look chic (and work well in some lighting conditions), but a white dot/tritium vial combination sight is highly visible in all lighting conditions, from bright light to low/no light.

    Please do yourself and her a favor and put an XS Standard Dot sight on the 640. I have Standard Dots on two 640s and a 340PD and wouldn't part with them for love or money. For me, the dot is the perfect size relative to the J-frames notched rear. Visibility is fantastic, and accurate shooting is no problem (provided the shooter is capable of it) out to 25 yards or more.

    And yes, before purchasing the Standard Dots I agonized quite a bit over the Standard/Big Dot issue, and am very pleased that I didn't allow myself to be won over by the high-pressure salesmanship on the XS website, where there is (or was at the time) a FAQ page that all but forced the Big Dot down people's throats. If I recall correctly, it even resorted to ridicule of those who opted for the Standard Dot by opining that most such purchasers were "game-players" who "only shot at stationary targets" or some such demeaning nonsense.

    In fact let me bestir myself and see if I find that page.

    Yup, here it is, from the XS website FAQ. The below quote can be found at its original location here: http://www.xssights.com/faqs.html

    Well, I suppose if they've convinced you to go with the Big Dot, so be it. It's a lot better than a gold bead sight, which I hope you decide against.

    Owen,

    The reason she wanted a gold bead is because she loves the one on her 627PC. That being said, I have tried to convince her on tririum. The other night, I took her out on the porch in the dark for a comparison. Her gold bead was completely invisible, and the night sight on my 586 was bright and very visible.

    She said that her only complaint about it is that it is difficult to sight in full light, being a black ramp. Last time we were at the gun shop, I showed her the tritium sights with the white ring. I think she's sold. Thanks for the input, and it looks like we're going to get her the tritium.
