What is best red dot for S&W 380 ez Expert Answer

The best red dot for the S&W EZ .380 will depend on personally preference. However, to mount a red dot to the S&W Shield EZ you will need a dovetail red do mount. To get the correct mount you will need to first pick a red dot then get a mount that fits that red dot mounting footprint and the rear dovetail of that gun. Please email us at techsales@opticsplanet.com for more information.

Holoson HS503R by A-A-ron, August 29, 2022
Great optic and got for a great deal on OP. The red dot function took a bit to get used to since it's different than others I've had. Looks perfect with the Scalarworks mount. It doesn't have the largest sight picture but enough for a cqb riffle.

Glass has better optical quality than Aimpoint T2. Circle dot reticle is crisper than Eotech in a much smaller and lighter package. More than bright enough for any situation on this planet. The mount sucks. The optic is compatible with all aimpoint m...

Amazing optic by Brady, January 19, 2022
The sight fits the rail perfect and looks great. There was no movement after 300 rounds. I love the variety of sights you can use. The adjustments are easy and it was simple to sight in. I’ll be buying another.

Better than Trijicon by Holosight reviewer, April 26, 2020
This sight came with a CMMG 9mm pistol I purchased. My father and I took both his (300 blk) and my (9mm) banshee's to the range to test out, and this sight viewed far better than his Trijicon MRO. The Trijicon showed substantial echo past the initi...
