This is a brand new stainless steel grip screw for vintage and obsolete Smith & Wesson K, L, and N frame Target & Magna grips (It will not fit the new "Classic Series" grips). The OAL is 1.259" and measure 1.160" under the screw head to the end of the screw (give or take 0.002"). Some S&W Target and Magna grips had their grip screw escutcheons recessed more than others - in some cases this screw may be a tad too long (easy to shorten) but it won't be too short for any of the sizes.
