A couple Sig RomeoZero optics showed up by surprise at the shop I work at and I snagged one to try out. Initial impressions are positive, and that it has a chance at being outstanding for its intended role.
First, the optic is not built or marketed as a duty grade optic; it is a polymer body and apparently polycarbonate lens, meant for the concealed carry crowd. The construction accounts for the optic’s very light weight, .3 of an ounce on the shop scale.
I find the window and dot very useable for the size of the optic. Mine is 6moa and has plenty of brightness for max daylight. The window has a slight bluish tint that is less pronounced than many other optics, and the housing is minimal enough that overall vision with the optic is quite good.
I really like that the dot is a plug and play solution for my p365xl, including a rear sight notch in the optic housing and that is regulated to replace the rear irons. The dot matches up with the irons from the factory, which is pretty cool.
Sig advertises a battery life of up to 10 years, which I assume is 10 years sitting in the safe with the motion sensor dormant, but we shall see.
The emitter is the primary concern for me, it is not shielded in any way, simply recessed into the housing. This optic is in no way waterproof, we will see how that translates to daily carry concealed.
We shall see if I can break it. If not, it is a neat little optic and has an almost perfect form factor for the size gun it is built for.
