Excellent, low-mass sight for pistols or other platforms
on December 10, 2013
I purchased this for the S&W M&P .40 CORE. The CORE comes with an adapter plate (#2) that fits the JPoint perfectly. This is an excellent optic with some trade-offs.
First, the unit is not built like an EOTech; the housing is polymer and the lens is acrylic. While this might seem a disadvantage, it makes the Jpoint incredibly lightweight. It of course does weigh something, but in real-world terms it weighs practically nothing. This has a couple advantages: it doesn't change the way your pistol balances/handles, and since there is no mass on top of your slide, there is minimal inertia from the recoil.
Jpoint states that they went with the acrylic lens for similar reasons; low weight and durability. I read several reviews of CMore sight users that experienced cracked glass, which will not happen with the JPoint. The trade-off is a slightly less clear optical lens, but the dot is all you need to see anyway. Basically red dots/holographic sights allow you to keep both eyes on your target, with the dot super-imposed on your target. So that makes the acrylic lens less of an issue.
You cannot turn the Jpoint off without unmounting it and removing the battery. It does come with a protective cover however that keeps the dot on the lowest power setting to conserve battery life. The upside is the sight is always on and available, provided of course the battery is good.
To compensate for the lack of power on/off and adjustable brightness, the Jpoint adjusts automatically to light changes and it does so very well. Standing near a light switch in a completely dark room, I can switch the light on and watch the red dot get much brighter instantly, while a flip of the switch back to dark makes the dot shrink and dim to its lowest setting. It works instantly and perfectly.
Overall I'm very happy with the Jpoint, with the only unknown for me being its long-term durability.
