Dave,
Thank you for your e-mail and the interest in our TRUGLO handgun sights for the Smith & Wesson Shield pistol.
The New Smith & Wesson Shield pistols (9mm & .40 caliber) do share the same front and rear dovetail dimensions as the Full-size and Compact Smith & Wesson M&P pistols.
There is a correct POI (Point Of Impact) result and overall performance and fitment is acceptable when our handgun sights have been installed on the Smith & Wesson Shield pistols.
We have noticed a small detail we feel obliged to bring to the attention of all potential owners of Smith & Wesson Shield pistols if they are considering installation of any of the TRUGLO sights for the M&P series of handguns:
TG131MPT
TG131MPTY
TG231MP
TG131MP
On the rear sight ONLY, there is a slight protrusion of the sight base that extends approximately (0.015") beyond the upper portion of the slide's radius top left/right edges. This slight extension does not extend past the overall width of the slide and in fact remains well within the overall width of the slide.
Please see the photo of the current TG131MPT rear sight installed on the Smith & Wesson Shield.
In our opinion, the rear sight does not present an opportunity to become snagged on any material, nor will it interfere with holster fit and operation. While very insignificant in its presence beyond the slide's radius edge, we do not recommend the rear sight be modified in any fashion as to minimize this overall width. Any kind of revision to this sight may result in damaging the tritium or fiber-optic components of the sight and will void the TRUGLO warranty.
At this time, we are working on a revision to this sight, where its overall width would be reduced enough to alleviate the small portion of the rear sight that comes past the radius.
We hope to have this revised rear sight available as an inline change and that will be incorporated into our current four sight selections for the Smith &Wesson Shield pistols, detailed above.
Once we have established a specific beginning to the manufacture of these sets of sights with their revised rear sight platform, TRUGLO we will be able to relate the identity sight sets with this structural change through production coding and make Smith & Wesson Shield owners aware of this better option for their pistols.
In the meantime, we do not feel there is a problem to install any of the following sight sets on your Smith & Wesson Shield TG131MPT TG131MPTY TG231MP TG131MP and look forward to even better installation options in the next few months.
We appreciate your interest in and choosing TRUGLO products.
Shoot safely,
