Not for indoor use! - HiViz LiteWave H3 Tritium/Litepipe Pistol Night Sight Set for Glock Gen 1-5 in .45 ACP, .45 GAP, and 10mm

These sights came standard on my S&W M&P Performance Center 380 EZ Shield.
Boy do they LOOK cool in the ad copy and on the gun.

But boy did they suck at the indoor range that I go to.

As others have said, if you plan to use these sights primarily on a gun at your local indoor range, I would pass on these sights.
They do not seem to respond well to artificial lighting.

I took my new 380 EZ Shield and a Glock 48 to my local indoor range recently. The Glock had its standard white 3 dot sights. The Glock sights were a pleasure to use compared to the HiViz Litewave H3 sights. The H3's were dark and a strain on the eyes to attempt to see. They made shooting the 380 EZ not fun. I am no expert in what type of lights my indoor range was using, but they did not play well with the Litewave H3 sights.

Sad when standard OEM Glock sights are significantly better than S&W Performance Center chosen sights.

I gave 3 stars as I am sure that these sights will perform as expected outdoors.
