Better combination than i expected - ADE Advanced Optics RD3-015 PRO Shake Awake 1x Reflex Red Dot w/SAR9 Optic Mount Plate

I bought this mostly because it already came with the mount for the SAR9. Trying to figure out which optic fits which plate can be confusing, so having everything together made the decision easier.

Getting the original rear sight out was the hardest part. I used a sight pusher and after that the installation went pretty smoothly. The plate fit securely and the optic mounted without any modification.

I've taken it to the range four times since installing it. The zero has remained consistent and the shake-awake function responds immediately when I pick up the pistol. The sight picture is also better than I expected at this price.

Overall, this is a nice upgrade if you already own a SAR9 and don't want to spend the money to have your slide machined.
