Picked up a a Shield 9mm at my local dealer. I was on a list for 5 mos. and glad to finally get it. When I got out to my car I had to remove it from the box and look at it again. Then I noticed that the serial number didn't match what was on the box and the trigger felt hard. Went back into the store and found that it was a MA compliant 180051 with a 10 1/2 lb trigger I returned it for a refund and said no thanks. Later that day I was called again. More on guard now I was able to pick-up a M/N 180021 with a 6 1/2 lb trigger. Buyers beware.
