Update (10/23/17)

Sorry everyone, been a busy couple of weeks for me ( both families in town cause I got hitched.)

Finally had a chance to shoot a little with the light on my pistols. I placed it on 3 weapons, Sig P226R (9mm,.40, .357sig,) M&P Full size (9mm,) and a P229R (9mm,.40, and 357sig.)

Put about 50 rounds of each caliber on some paper and was very happy with the light.

No weirdness or issues that I noted.

I did accidentally activate it once as I got a little over zealous in drawing quickly and presenting on the P229R ( I have long fingers and I jammed the switch as I formed my grip on the slightly shorter pistol .)

Love the fact I can charge it attached to the pistol though, I have a portable battery pack plugged into the USB charging cable in my little pistol safe so it's always charged when it goes to sleep for the night!!!
