Does anyone know if there is an availability issue with the P320 9mm full size? I have been checking with local gun shops for over 3 months but have been unable to locate any P320's. Gander Mtn. advertised the gun for $549 ($100 off) but I have not checked with the local store to see if they have it and I would rather buy from a local dealer than a big box outdoor store. Also, is there any truth to the internet rumors that SIG is making modifications to the P320? Since none of the local dealers have the P320 to test fire, I would like to know how current P320 owners like the gun and if there are any issues?
