I understand that the 9MM is popular, but they are literally falling off the shelves at every gun dealer within 200 miles of here. It is also suddenly easy to find .380 or .40 also. Meanwhile there are zero in .45acp. I think S&W is leaving lots of money on the table. I have spoken to most of the local shops here, they all have stopped taking orders for them, they have dozens clients wanting them and they get nothing but crickets from S&W. I am about a month from just buying a G30SF, I vastly prefer the S&W, but both fit in an IWB and will do the job.
