I have several .. LG 436s on three Glock 26s and two more LG 436s on a couple of Glock G 19s. I guess you can tell how much I like mine.
Yes, they adjust for vertical and horizontal. Easy and fast (takes very little turn to get adjustment so don't over turn the adjustment screws. Easy to mount, good battery life and I have never had a pair go out of alignment. A friend has one on his Kel-Tec and we shoot a LOT. He pocket carries his Kel-Tec, I holster carry IWB one of my G 26s and we have zero issues with these laserguards maintaining perfect alignment.
I cannot say enough good about them and if you shop at Shooters-Resource
http://www.shooters-resource.com , you'll find some great prices (after you put the item in your cart). Excellent and fast shipping too. Good retailer.
I simply cannot imagine your not liking them if you decide to go ahead and buy one.
