What is the purpose of the laser sights in the first place?
I have 3 and technically they are excellent, but laser sights for me have only 3 uses:
1- able to aim behind cover with less exposure
2- moving targets
3- zombies
For low light, no light or better visual I prefer a good night sight (and a flashlight). Never runs out of battery and does not give away your position.
If you watch the promotional video from crimson, they emphasize both scenarios.
Zombies are for military, swat, airsoft, video games etc. the pros. You became too visible. It's aka shtf. Than you might consider a red dot, but in a pistol it requires a big mount. And again, batteries.
