.45Auto Vs. .45ACP Whats The Difference?

[Rugerman]

what are the main differences? also this is of topic but it is a pistol section, so the SA XD 4inch Model has a 14 round mag i believe. Correct? you cant have any mags over 10 rounds regardless rifle or pistol right? Thanks in advance

45 Auto and 45 ACP (Automatic Colt Pistol) are the same thing.

The law for magazines are the same for both rifle and pistol mags.

"45 auto" is a generic term that means "45ACP".

There's a new 45 round for automatic pistols, called the 45GAP ("Glock automatic pistol" that is a physically shorter round with supposedly same performance. It's a new round and it remains to be seen if this will get any marketplace traction besides Glock.

You cannot acquire new hicap magazines (those over 10 rounds) in CA. If you owned exsiting hicap magazines in CA before 1 Jan 2000, you can retain and use them. Otherwise its 10 rounds or less.

40 is cheaper, I believe, but 45 is more fun in my opinion, and the opinion of many.

It's not as loud, the recoil isn't as sharp, and there are many excellent weapons designed around 45. The 1911 design comes to mind.

.357sig is even more fun to shoot. But the .45 is my favorite round.

I just ordered another 1k rounds of 45 on the net.

It won't last long.

.45ACP is my favorite pistol round. Very enjoyable to shoot. .40 is so jumpy

Both of these rounds are fun to shoot if you looking for a first gun for target or defense the 40 s&w is a great choice the ammo is a little cheaper so you can shoot more.

"45 auto" is a generic term that means "45ACP".

Also, a number of gunmakers are using "45 AP" interchangeably with "45 ACP".

I once bought some brass from an E-bay for "45 AUTO" and it turned out as "45 AUTO RIM" ...same dimensions as ACP but headspace is 516 rather than 480

How much rimmed do you have? I'll trade you for 45acp if you want.

[Rugerman]

so .40 is cheaper but .45 is more fun to shoot....... I'm looking for HD and an all around pistol maybe even for some rabbits. I 'm thinking about the Sig 220 Equinox but 1k is a little over the budget. i'm looking for around $600 so i was thinking the SA XD in .45 or .40S&W And does anyone here have the 4inch ported model?

[HKROB]

If you want a sig you might want to look at the CPO (red box ) p226 or p229 in .40 sw they cost $500-600. I have a sig p226 40 sw & HK usp .45 acp I love them both

.45 Revolver or .45 Pistol??

What is the difference between rounds as I don't own one but have a friend who has a revolver and uses the moon clips. I know there is a rimmed round for the revolvers but what exactly is the difference or benefit?
