I took a new shooter to the range today, and I taught him the safety rules. Set him up to shoot and then let him go for it. He loaded a round of 9 mm by accident into my XD-40. The gun fired but had a failure to eject. I checked it out and holy mooly, the 9mm blew out to the diameter of the chamber. The gun fired subsiquent 40 S&W rounds w/o problem. Do you think the gun was hurt?

A single 9mm in a .40 chamber?


Hell no, unless that gun was weak from the factory, it ain't hurt.

Obviously, it fired fine after that 9mm...


Take it as a lesson learned and don't let it happen again.

I would just check your extractor for any sign of damage.

[atek3]

extractor and ejector look fine.

Good to hear. I'm sure the gun is ok. :cool:

Wasn't there a post a while back about 10mm in a .45 ACP and other such goofs with pictures? Or am I remembering something else?

[4v50 Gary]

Doubt it. I fired a 9mm from my 45 once. :eek: Taught me never to allow someone else to load your magazine for you.

Your gun wasn't the first to have that done to it and it won't be the last. A coworker did that same to hie Taurus PT101. No problemo.

Having mixed calibers availabe can get interesting.
Specially if the smaller one fails to fire and is NOT gripped by the extractor.
Rapid clear drill MAY leave the smaller one in the barrel.

Subsequent trigger pull gives a lesson on what shooting with obstructed barrel looks like.

Did that once with a 9mm between my G17 and G22, 9mm casing blew out to diameter of 10mm chamber. Nothing else was damaged and we just don't talk about it hereabouts in polite conversation.

Learned a valuable lesson to always check ammo & mags when shooting.

It should be fine!! :)

I saw this at the range once.

The lady in the lane next to me (obviously a novice) was having frequent jams and I noticed the holes she was making in the target looked torn rather than nice round holes.

I offerred assistance and found she was shooting 9mm in a .40 chamber. I guess she just pointed to a box at the counter (thinking it's all the same) and the guy sold it to her assuming she knew what she was asking for.

The interesting part was holes in the paper target! It was bad enough that I noticed it before I realized what she was doing. Bullets must have been tumbling or something. :confused:

Sounds like you're still good...just try not to do that to many more time ;) I learned w/ newbies to give them the right ammo before they start shooting...but I guess you know that now too :D

Doubt it. I fired a 9mm from my 45 once. Taught me never to allow someone else to load your magazine for you.Try that with a 4506 sometime. When you drop the slide the entire cartridge goes flying out of the barrel at about 7 fps. Terrible ballistics- makes a .30-30 look like a flat shooter. I wouldn't want to guess at terminal ballistics...best guess would be right about .25 ACP level. It is, however, very low noise and low flash, and the recoil is negligible.

:D

I think you'll be fine, too, and it sounds like you have an interesting conversation piece!

At the last Glock shoot in Dallas, the guy who shot in front of me did that.

He was making reasonably good hits, but the gun kept jamming.

About six years ago, I got back into pistols after a lengthy absence during which I didn't even own one. After a long afternoon of shooting 3 different calibers at the rental range, I loaded 7 rounds of .40 in a .45 magazine. Took one round to convince me that something was badly wrong: the sound was funny, and the bullet keyholed in the target.

The .40 case, of course, split. No harm to the .45.

Very embarassing. :o

I don't shoot when that fatigued any more. I also trust my gut a lot more...if something sounds/feels/smells/looks wrong, I stop and check it out immediately.
