    My favorite CCW is my 10mm Glock-29 loaded with Underwood 115 gr. 1700 fps Xtreme Defender ammo. These rounds cost me almost $2 per round when you consider shipping. I put in lone-wolf a 10mm to .40 caliber conversion barrel and normally practice with 180 gr .40 cal. ammo that I buy in bulk from Georgia Arms. The recoil is very similar. It's in a big ammo can and I pull out a hand full of ammo at a time and load up my magazine. Sitting next to the .40 cal. ammo is an identical looking ammo can of 10mm bulk ammo that I also bought from Georgia Arms. Today I reached into the wrong ammo can and grabbed a big handful of 10mm ammo and started to load the magazine for the G-29 with the conversion barrel in it. I caught my mistake when I looked at the length of the 10mm ammo.

    I wonder what would have happened if had not discovered my mistake?! I think the 10mm ammo would have loaded most of the way into the .40 caliber barrel but I don't know what would have happened if the slide tryed to slam that big round into the barrel? Is there a danger that I could have accidentally exploded a 10mm round in a .40 caliber barrel? I'm sure that would be BAD if that happened, if it could have happened!

    I'm going to move the ammo cans further apart.

    Thanks for any insight/advice you can give me.

    I'm a random ******* on the internet and with the authority that comes with that prestigious title, I think it would be just fine. I don't think it would chamber or go off.

    I agree it probably would not chamber. But if it did chamber, being 10 mm and all, what happened next would probably be an explosion of Biblical proportions; so extreme that perhaps a new word to describe it would have to be invented. Or it would have just fired fine.

    Nothing would have happened.

    Relax, you were in little if any danger.

    The 10mm is longer, so it probably wouldn't not have even chambered. Even if it did, guns are overbuilt with a big safety margin, so you probably wouldn't have even damaged your gun.

    Plenty of 10mm pistols are built on .45 frames. Wear is accelerated, but there is no real danger.

    The issue is about 0.1 longer area that is not supported. Most of the cartridge is supported so it will build pressure until the case ruptures.

    Then there is a gap and the gas / cartridge has a nice gap to escape into.

    Probably wouldn't chamber. OTOH a 300 BO will chamber in a .223 gun.

    I color code my magazines after seeing this picture.

    The tag says 40mm barrel. So it would probably just slide out the other end

    Sorta..except a slide will go forward...

    A cylinder won't swing in.

    But..what I would guess..the slide won't go far enough forward to make the trigger move the striker rearward..meaning it won't fire.

    The out of battery firing probably can't be much out of battery.

    A .40 cal bullet[10mm] would be ejected out of a .40 cal barrel [10 mm]. Even a conversion barrel is built to withstand proof load pressure. That is my VERY un expert opinion.
