Wow.. some long waiting times there. I don't understand what's taking so long for some and not others. I had my non restricted first, so possibly mine took less time than others because of that, but still, I actually think mine was less than 6 weeks.. taking a year is very unusual unless they're having trouble getting in touch with references possibly.
edit : Be very careful who you use as references. I made sure both my references were no-nonsense kinda people that had known me forever as a firearm user and were likely to answer their phone instead of letting it go to voice mail. I suspect that if they get a no-answer or voicemail, your application goes to a list for a re-try at a later date. How many times that happens before they contact you, I have no idea, if it happens at all.
Remember that "just the facts, ma'am" is not only a time worn cliche from some old movie, but a very relevant statement in this context.
IMO, the less said the better, remaining professional and clear of course. If I used Aunt Susie as a reference, who thinks I'm a wonderful person but has no clue about firearm safety, that's not a good reference to a police officer who's trying to assess whether it's safe to let me buy a gun or not.
I'd suggest trying to use people who are already RPAL holders, don't have a criminal record, and can hold a clear concise conversation without blathering on about this and that. They should answer the questions that are asked, not volunteer information about you.
Whether that will help, I can't say. I can say for sure that it won't hurt.
