.45 ACP or .45 Auto

[FIREFIGHTER769]

Ok, so this may be a stupid question, please forgive my ignorance. I picked up a SA XDs last night for my new EDC. But what is the difference in .45 ACP and .45 Auto. Is there any? I had some .45 Auto laying around, and loaded up a mag and stuck it in there, had the nose of the bullet got stuck on the feed ramp. I cleared the weapon and removed one round from the mag, and tried again, and it worked fine. I just dont want it exploding in my hands because I didnt use the correct ammo. (By the way I'm not a dumbass, its an honest question. I have only ever owned .40 S+W, so this is new to me) Thanks for any input

Same,45acp stands for Automatic Colt Pistol. Just don't try 45lc not the same at all.

The .45 ACP (11.43×23mm) (Automatic Colt Pistol), also known as the .45 Auto by C.I.P., is a cartridge designed by John Browning in 1904, for use in his prototype Coltsemi-automatic .45 pistol and eventually the M1911 pistoladopted by the United States Army in 1911.[SUP][2]

Someone will come along with another answer I'm sure .... But I believe them to be the same... I know I have shot both from the same gun

Yup different name but same stuff. The odd ball in .45 rimless ammo is .45 GAP which is not the same round as .45 ACP...

Yep, .45 Automatic Colt Pistol.. Same thing. Not to be confused with .45 Auto Rim.

Had some Mecgars mags that did the same thing. You just need new mags and all will be fine.

I made that mistake before. I went to Walmart and bought the first box that said 45 on it because it was a dollar less, lol.

You are doing what every responsible gun owner should do. That is either research or ask for help. Irresponsible people assume. That is why a lot of "unloaded" guns injure people.

I know everyone else already answered your question, but I will add that 45 auto and 45 acp are the same thing.
