Thanks for reaching out Drew! I'm afraid I can only speculate myself. I have not seen W Train & Defend series ammo on the market recently, that's for sure. But in my personal experience, Winchester doesn't definitively discontinue a product line until they have removed it from their website. The fact that winchester.com/Products/Ammunition/Handgun/W-Train-and-Defend still exists leads me to believe that they haven't officially axed this one. That said, you may rightly assume we're not going to see it again – but there's a chance they'll begin producing it in significant quantities again. I wish I had a definitive answer for you!
