Is it .45, or is it Memorex?

Sorry, couldn't resist the old commercial. OK, if a white box of .45, is .45 auto, is that the same critter as .45acp? I think so, but was curious after a trade for this box ("auto") and not see the acp designation. Best to be curious in all things that go bang.

Yes it is the same

Better check---it could be a 45 auto rim.

45 Auto & 45 ACP are the same & interchangeable
45 Auto Rim, however, is not
45 GAP made by glock is not
45 ACP is not.

All and any more responses appreciated. Figured it best to ask and certainly it's a good way to use a wide audience. Many thanks.

I had the same question on my first purchase!! LOL

45ACP and 45AUTO are the same...

I left and had to come back later to pick up my ammo that was sitting right there... I got lucky because it was the last two boxes they had in stock!
