Green laser for sig 365 - Viridian Weapon Technologies E-Series Laser Sight

I already have the Lima on my 365 and a holster for them. I thought this Viridian would be an upgrade as the Lima requires you to put pressure on the switch to activate the laser. I want to mention I have the Viridian product on my Hellcat and am mostly satisfied with it. It does shift off of center with a little pressure or carry use. Not enough to matter at most reasonable distances. Back to this item though. The tools that came with it and the small soft screws were a let down from the very start, before i even got the halves apart the flimsy design made me doubt this piece would ever go on, stay on or stay centered. It's very cheap and very poorly designed. What scares me about a piece like this is that it's easy to envision missed shots and ones that possibly harm others due to the design. It is an unsafe product with huge risk. Again, I have at least 5 or 6 Viridian products I am happy with but this one was sent back in less than 30 minutes after arriving. Optics Planet - great service and return policy when things go bad.
