I've done a bit of research (thanks Glock Talk!) and narrowed my choice in tactical lights down to the Procyon Xti (for Glock 23). Seems like the best combo of size, features, and price for me. Luckily I found one at a decent price ($120 @ Black Bear Sporting Goods) but the impression I got from surfing around was that these were discontinued. Have these been discontinued, and if so, why? Seems to have gotten enough praise, seems odd they'd stop producing it. Anyone heard anything?
