wow I'd have to drill a hole??? I was assuming I would be buying a sight blade with the tritium already mounted. Hoped I could just drift out the pin holding the stock sight and replace with a new glow in dark blade one. Hmm thanks for the heads up.
BTW I have the CTC grips on my gun and love them. Discovered that little gun is really accurate with those grips. Just that I thought there might be a time when the battery might not work or I couldn't get to the main switch and the tritium sight would be a nice backup. From the few I've handled, I like the way the CTC grip switch works on revolvers much better than on the sample autoloaders I've tried. On the 101 my fingers always touch the switch but on auto loaders I often have to shift my hands around to touch the switch - I have small hands.
