Just wanted to say Giday to everyone and thanks for a very informative well laid out forum. A-lot of really helpful info for a newbie to shotguns. Jury is still out on my 712 ALS and the mag plug retainer, contacted CZ via e-mail today, and will followup with a call tomorrow. Not sure I will get a response before new year, but i'm itching to shoot that dang thing.
Cheers
