## Description

While it is possible to install this mount without the use of a Gunsmith, we recommend hiring a professional gunsmith. Please note. Unprofessional installation such as improper torque will result in screw loose, not holding zero, damage to the firearm/optic and personal injury. When you first receive ADE red dot. It might has a picatinny mounting plate pre-assembled (might be packaged separately in the retail package, depends on the ADE model). Please use the allen wrench provided to take out the 2 hex screws(M3x6mm) on the top behind the glass frame. It will disconnect the red dot from the picatinny mounting plate. You will then be able to attach the red dot to a variety of handgun mounting plates that are sold separately（please read the description to see if this listihng comes with an optic plate for a specific handgun).

Review: I could wear size 16 shoes & say they fit. - I was really excited to buy this product. I like the brand name and quality, especially with it's price point. I was especially excited that it states the design is specific for a Sig p365 non XL. When I read that, it implied to me that there would be some Elegance in how it fit on the gun and in keeping with the purpose of the gun which is micro concealed carry. When the package arrived I took it out and when I held it against the gun and I was convinced I received the wrong product. So I checked the paperwork and sure enough I had the correct item I ordered. I don't have the exact dimensions but it sticks out extra on both sides of the slide plate, and the height is increased dramatically because of the adapter plate. I thought maybe I was missing something and I tried reaching out to the seller. But they have chosen to have desertcart handle the customer service. What desertcart customer service rep understands Carry conceal and the nuances of what that means? I've tried before and didn't bother this time. Now I could put on a pair of size 16 Shoes even though I wear a size 8 and they would go on my feet. But they don't work and neither does this sight for a Sig p365. I've returned the item and recommend the following: Sig Romeo Zero Holosun HS507K-X2 Crimson Trace Rad Micro Pro All of these can be purchased on desertcart.
Review: Works absolutely great. - How easy it was to install.
