According to an online published report by the NY Daily News and another report I watched on Fox Cable News 01/19/2010), the Trijicon sight manufacturing company of Wixom, MI is placing coded references to bible verses on their gun sights right next to the serial numbers. Reportedly there have been several complaints about this from soldiers and Marines received by Mickey Weinstein of the Military Religious Freedon Foundation. (I'd be willing to bet that this organization name should read Oppression instead of Freedom, but that is just my guess.)
I happen to own a pistol with Trijicon sights. I just checked them out. On the right side of the rear sight there are four tiny characters, it looks like H3 08. There are many biblical translations, I chose, pretty much at random that from the New American Standar Bible (as per: http://bible.cc/hebrews/3-8.htm:
"Do not harden your hearts as when they provoked me, as in the day of trial in the wilderness"
Not having to hard a heart is probably good advice for anyone who carries a weapon.
Now, mind you, my eyes are not what they used to be and I'll have to double check to see that I got the letter and numbers right. If I did, this post will remain unchanged but if I got em wrog then I'll revise chapter and verse later on.
By the way, according to one report, Trijicon has confirmed that these codes are indeed references to bible verses. I'd buy from them again - no problem here. They make good stuff, such as the set of night sights on my Glock 26 and if it is empowered by heavenly light - well good for me.
All the best,
