Luckily you have chosen a caliber that is available. Everyone has 40 cal. The best bet is to look for a gun show in your area. This will save on shipping. Large quantities will cost you in the long run because of shipping. As far as Cheaper than Dirt goes I won't buy from them either. Too many bad stories lately.

To preserve liberty, it is essential that the whole body of people always possess arms, and be taught alike, especially when young, how to use them... -- Richard Henry Lee, 1787
