Apex Tactical Specialties announced two new parts for the Shield and for the SD pistols from Smith & Wesson. For each pistol line, Apex is now making low-profile and no-profile loaded chamber indicators. These new parts will work on guns chambered in both 9mm and .40 S&W.

According to Apex:

Designed to eliminate the obstructive interference with the sights of the factory installed Loaded Chamber Indicator, the Apex Low-Profile LCI maintains the visual and tactile features of the factory LCI without interfering with the sight picture while the Apex No-Profile Block option simply replaces the factory installed LCI and fills the void in the slide with a flush fit.

The parts carry a suggested retail price of $19.95.

Apex made this video further explains the parts and shows their installation:

I should note that the loaded chamber indicators are only found on the California-compliant versions of the pistols. Owners in other states do not have to worry about these superfluous parts.
