I'm not new to using red dots, but this was the first one I've bought. For use on my gen 1 Sig 365 XL, I needed a red dot that included a rear sight and with the Sig, it's a correct match for the front sight. If I had a gen 2, which has a rear sight that's separate from the sight plate, I likely would have chosen the enclosed version, which does not have the built in rear sight. The sight was easy to install, easy to get zero'd and as long as you've got some decent training, easy to pick up the dot immediately. Please make sure you use the correct screws for your gun and that you've properly torqued them. There are three sets of screws included.

I have a few of these. I have the 2/64 moa & the 3 moa. I’ll take the 3 moa all day long. The unit is solidly built. The dot is very crisp and allows me to quickly acquire it. The battery is easy to access from the side of the unit. The adjustment is a little unique. You need a very small star bit to make the adjustments. Keep the wrench with the optic. The brightness buttons are again on the side of the unit and functional, even with gloves on. It is a little pricey, but you are also getting a well built American assembled Sig optic.

This Sig X Compact fits all the P365 oem platforms l8ke a glove (no gaps and solid fit). With the Copper-color Radian Afterburner comped barrel pkg, it makes my p365x look custom. I have put over 500 rnds thru my sig and this optic is still perfectly zeroed. They ain't inexpensive! But high end quality typically isn't and it's on my EDC so quality and reliable function is a priorty.

I had a Romeo Zero on my P365X. It was one of the first compact RDS sites available and it was inexpensive. Frankly, it was adequate at best. The plastic lens easily scratched. And battery changes required removal and re-zeroing each time. Unlike the Romeo Zero, the Romeo X is QUALITY! Clear glass, side load battery means no removing and re-zeroing with battery changes, the housing is all aircraft grade aluminum and takes plenty of punishment while protecting the optic perfectly. The multi reticle is BETTER than the Holosun and the recessed control buttons are great! No accidental operation but not difficult to access. I have a Leupold Delta Point Pro, Holosun 507C, and 507k and this is my favorite RDS bar none! I like the Romeo X so much Im actually considering replacing the Delta Point Pro on my P320 with the fullsize version.

Super nice compact green dot. Fits Sig 365-380 just fine. Very easy to install, use and sight in. Remember to push the optic slightly forward as you tighten mounting screws. Used a torque screwdriver to torque screws. But they give you wrench, so you can just wing it. Use a bore sighter to get close, then tweak it as needed. I did not buy the sig sight-in app. Green dot very bright and adjustable.

This is on par with an EPS Carry. It is durable, sleek, and holds zero just fine since I installed it about a year ago. Battery still going strong, kept at 8/12 brightness. Compared to the EPS Carry: The window has a blue tint. I like it personally. The deck height is slightly lower. The battery tray protrudes a bit on the right side. There is no way to lock the buttons, so if you like racking the slide from the rear and accidentally click the buttons, you will inadvertently adjust your brightness.

It seems high quality, the glass has a blue tint which is annoying but many have tint. I have astigmatism and the dot is crisp for me over my Trijicon RMR and SRO. I mounted this on a ARC division Glock 43 slide and it fits correctly. If you get this optic you can use standard sights. I don't like that it has a non standard battery like every other optic that uses CR 2032 batteries. So you'll have to stock up on a new size. I've banged it around and it's fine, it seems sturdy, it seems reliable. It claims it's assembled in the United States and it comes with a unconditional lifetime warranty, but I'm skeptical Sig will honor it with their now terrible reputation for QC in their products but who knows. I chose this over a EPS carry, maybe wish I didn't idk I personally have had only bad luck with holosun elite optics and am not buying a a RMRcc, so this seemed like a shot to give. Also this is not the enclosed version, it is a standard open emitter which is what I wanted because I don't really personally trust closed emitters as I have also had bad luck with an aimpoint ACRO and this sig optic is going on my carry gun which I'm not too worried about not being able to use the optic if it gets wet.
