It holds a zero very well and works as i expected it to. The tolerances are pretty snug though so it shouldn't be off very much when you put it back on.
They're a perfect fit and give an amazingly crisp sight picture. Easily installs with a sight pusher tool.
Excellent no frills sight. Great price. Wishes i had upgraded sooner. Nice bright sights. Better than my glock with oem night sights.
Each dot illuminates perfectly in low light. Just the right amount of brightness at night. Excellent visual sights recognition in both daylight and darkness.
Tritium is dead. Arrived extremely dim and with almost no tritium glow left. Their either old & outdated or defective sights.
