When I ordered it said nothing about a back order. They said my order would be here in 2-5 days.
Did it say it was back ordered when you placed your order?
I got a follow up email stating the order had been processed. I would assume they would tell me if it was out of stock?
On editing today, I just got notice my ammo will be here on Monday.
I was always able to get it from Cheaper-Than-Dirt without backorder. I haven't ordered any in some time now...too expensive to practice with, although, I did run 100 rounds of the DPX initially---no problems.
If you think DPX is expensive in 380, price the DPX 62 gr. in 5.56 NATO--now that's expensive! I have two 30-round mags for my SU-16C.
