I own the DA/SA 226 Legion, I love the gun. I also got it for 20% off.
If you're going to get a 226 but can't justify the high price tag then get a regular 226.
However, the Legion is a beast and to get the same quality from a normal 226 would cost a lot more than the Legion is priced at.
It all comes down to A) Do you like extras? or B) Do you just want a reliable great shooting gun?
If you like bells and whistles then the Legion has everything you need. If you just want a quality firearm get the regular 226. The Navy isn't very special anymore anyway. The Seal Teams dropped the MK25 in favour for the Glock.
