Welcome Back Dave,
I enjoy studying and have collected the complete catalog of 1976 Ruger Liberty Line of SA/DA revolvers, M77's and 10-22's, M-14's, .40CAR, no attempt to tackle the No #1 or #3.
My current passion and pursuit is the OM .44 in both FT and SBH. While I'm certainly no expert most everything I've learned has been from the members here or at there direction to read. ROCS members are more than willing to share there knowledge and encourage learning through displaying and writing articles. Many have befriended me quickly and as you know are well read and authors on many published articles, website hosts and authors of various books on Rugers.
I'm happy you found a way back onto the site.
