I was poking about on the CE Safe website and came across the "M1" and "M3" options from Ft Knox.

As I understand it, the M2 line was spec'ed by CE a few years ago and proved popular enough that some other big dealers have started carrying the line.  Maybe the same thing will happen with the M1 and M3.

No pricing info listed here but they probably aren't too terribly priced.  These certainly give a couple more options to those who're interested in heavier steel bodies and doors.

I just purchased a safe from ce safes. You will not be disappointed.  Went to their showroom and had it delivered within a week. Very good business.

Discrete and professional.
