Two local dealers have been out of stock since at least the end of November and can't get new stock from their distributors. There's a small but steady stream of them on gunbroker.com, though, if that helps.
I bought my Thunder 380 plus at our local US Money Shops about a month ago and have a Thunder 380 CC in layaway from the same store. That is all the Bersas they had or I would have all of them in layaway.
I attended a gun show in Joplin, MO yesterday, what a mad house, wall to wall people, lots of guns for sale, very little ammo. Several dealers had the BT .380 and .22, both for around $330. I love the feel of the BT .22, that may be my next purchase.
My dealer usually has a couple of BT380's and sometimes even 9's and 45's - they are a very popular firearm around Morgantown, WV - with good reason, 'cause if they all shoot like mine, they will be 'spot on' right out of the box!
