I've carried a Airlite N-frame (4") every day for a few years and consider it easy but I work outside & dress as I please.
High & tight OWB, under a tshirt or untucked button up shirt works for me if I want to cover the gun up.
The guns are so lightweight, high carry doesn't tend to want to roll outward like a steel gun, but a good belt is still needed. Several good holsters are available.
I have J, K, L & N frames, the width of the cylinder really isn't an issue for me.
Grips are a little more noticeable (at least with my wardrobe) than cylinder width, but I have big honkin Hogues on it currently. Rounded back grips cut that signature down but I don't care.
N frame grips are in practical terms the same size as K & L frame so no difference in hiding them.
I used to carry a 2 1/2" Python part of the time, you having a 2 1/2" barrel just makes it that much easier to cover with a shirt tail over my 4".
