Have you replaced the sights? I'm going to install Dawson Precision sights. Until I get that done, I've blackened out the rear white dots and painted the front dot red. I've found that to be an acceptable improvement for now. The Dawson Precision sights have a more narrow front blade with colored fiber optic. Less than $100.
I haven't replaced them, and hadn't given it much thought yet. For stock sights, they are decent out of the box, and I haven't gotten into big customization on any of my guns yet. I'll probably use these for the foreseeable future, but I definitely will be looking at some fiber optic ones in the future. Compared to the Taurus, it's incredibly nice to have a market out for the pistol instead of magazine shortages...
