Well, I am kind of gettin interested in this little thing. I have done a search and opinions are A or B, hot or cold, and about 50/50. I would like to know if you think the reliability has truly improved, since its introduction. Also, there are several "types" available, like the Tomcat, Alleycat, and Widebody. Various finishes and either an oversize or smaller safety. My big question is how much does the widebody weigh? And how wide is wide? I think I am going to rent one this weekend. Is there a certain serial # to avoid like that on the earlier NAA Guardian? Thanks ya'll.
