At 60, the other thing I have previously bashed as stupid, but now find immensely useful is a Laser sight.
I have a Viridian laser on my LCP, and the pocket holster has a magnet that deactivates the laser when holstered.
When you draw the pistol, the laser automatically comes on.
I can keep my focus (mentally, and in my bifocal age, optically) on the target without trying to tilt my head back to see the front sight.
Sounds like a nice rig. My .380 is a S&W Bodyguard Semi-auto and has a laser also. Nice design...has a button to activate laser on both sides right where your index finger rests while aiming...for lefty or righty.
