Are those with the teflon finish (tough to tell from the photo)? Or does D&H use that same finish on all of their magazines?
Can you work a deal on 100+ mags? Last year I did a bulk buy from www.44mag.com
for the D&H teflon with magpul followers (ininstalled) for $11.58 per magazine, delivered. If you have them in stock (or can get them) and can come close enough to that deal, I'd go with your shop.
