I've been at my job for almost 1 year. I'm pretty happy with it. It's not perfect, but I see it as an excellent opportunity, both for growth and for improving and expanding my skills.

The area I live/work in has a shortage of people with my skills and experience, and I've been contacted by recruiters pretty steadily for the past year and a half. That's actually how I got my current position; I was meeting with multiple recruiters, and opted for my current job over another (higher paying) position offered the same day.

Since then, though, several of the jobs I've been contacted about were for salary ranges significantly higher than my current one. In some cases, the range was 30-50% higher than my current salary. 

I haven't been pursuing these other jobs, because salary isn't everything, and as I mentioned, I'm happy with my current position, and would rather stay with a good thing than wind up in another job that paid more, but made me unhappy (my last job turned out really bad, and has made me particularly sensitive to that last point.

But the prospect of 30-50% higher pay... is getting pretty hard to ignore.

My first review is coming up soon. I don't know other people's salaries at my company, but I suspect I'm one of the most highly paid. My salary is the maximum of the range they were offering for my position, and I'm in a senior role on a small team.

I was wondering if there was a way to make sure my boss knows that my salary, while on the high end for my company, is on the lower end for someone with my experience and skill set, without making it seem like I'm threatening to leave the company. Is this possible, or should I just leave well enough alone, and hope that my performance over the past year prompts my employer to give me a nice bump to my salary?
