Great red dot. - Holosun HE407C-GR-V2 Green Dot Sight

I have several Holosun red dots on everything from pistols to rifles (407C-GR, 403C-GR, 510C-GR, 515-GM). They all have performed perfectly with no issues. I am running the 407C-GR-V2 on my Canik TP9SFX. I just wanted a simple dot only, so I saved a little money going with the 407 instead of the 507. I have around 400 rounds through the Canik and have not lost zero. Shake awake is a great feature of this optic and one of the reasons I buy Holosun products. I like to set them up and leave them on. The green dot is also very easy to pick up quickly. I highly recommend. Will be picking up the 507C for a Glock build I have in the works.
