I would like to know if the primer used for cal. .45, .40 and 9mm are the same in sizes or literally, the same.

Thanks.

exactly. the 45 uses a large pistol primer. the 9mm and .40 use a small pistol primer. can not interchange them.

There are a few types of .45 auto that use small primers, like the Winchester and Federal (?) NT's. Most folks will toss those, but I just separate them out from the regular cases and put small primers in them.

I see no harm in this, but if you're using a progressive press like a Dillon, getting a small primer case in mix will bring your progress to a screeching halt.

I keep the loaded small-primered .45's separate, and when I have enough I'll take them with me on a road trip where I might find a place to shoot where I can't easily pick up my cases. I consider them "disposables".

and there are differences between small primer 'NT" 45 ACPs, the flash hole is smaller in the Winchester.
