White Sound Defense (WSD) has just introduced their latest guide rod for the Smith & Wesson M&P. WSD doesn’t make just any run of the mill steel guide rod. Their designs have functionality you won’t find anywhere else and the typical attention to materials, coatings, and designs that you have come to expect from WSD.
The most noticeable feature of their guide rods is their extended length. The guide rod actually sticks out from the muzzle end of the M&P slightly to act as standoff in the event that a contact shot must be delivered. The standoff function of this guide rod makes it much less likely that the M&P will be pressed out of battery if the muzzle is pressed into someone or something when a shot must be fired.
The guide rod and spring are made from no compromise materials. The guide rod is made from durable 4340 alloy steel which is titanium nitride for corrosion resistance. The spring is made from music wire and then plated to prevent corrosion.
The springs match factory weight so that they do not alter the reliability of the M&P. I own several of these for my Glocks and they have all run like tops.
I should also note that the guide rod has a small transverse hole which can be used to wind the spring effortlessly onto the guide rod if you insert a paper clip. It makes it just as easy to install as a captured unit.
