Nevertheless, regardless of their shared ancestry by way of bullet diameter, they’re distinct and incompatible in most conditions.
Let’s look at these key variations intimately to know why.
The .40 S&W cartridge boasts a shorter case size than the 10mm Auto. This seemingly minor distinction in measurement seems to be a big issue. The .40 S&W cartridge is designed to be noticeably shorter. It is a elementary distinction, and the first motive for the potential points when making an attempt to chamber and hearth these rounds in a 10mm 1911.
The case size distinction creates a big discrepancy within the general size of the loaded cartridges. That is notably necessary for the feeding and chambering of the rounds inside the firearm. The slide has to perform correctly to ship and extract the spent casings. A shorter spherical may not be correctly positioned, resulting in a failure to feed, or a misfire.
The inner stress exerted inside the cartridge throughout the firing course of additionally performs a job. Whereas the particular stress rankings can fluctuate relying on the particular ammunition load, it is necessary to know that the 10mm Auto, normally, operates at greater stress ranges than the .40 S&W.

It is a extreme hazard, because it may launch high-pressure gasoline and particles immediately into the shooter’s face. This will trigger extreme harm.
The extractor is the a part of the firearm that grabs the rim of the spent case to take away it from the chamber. If the extractor is just not grabbing the casing appropriately, there may be a failure to extract the .40 S&W case, or if it does extract, it will not be correctly ejected, resulting in a jam. The marginally totally different rim dimensions between the .40 S&W and the 10mm Auto can compound this downside.
The 1911 and Its Innards
The 1911 pistol platform, with its elegant design and sturdy building, has been a favourite amongst gun homeowners for over a century. To know the potential risks, you want to be conversant in the particular elements concerned within the firing course of.
The chamber in a 10mm 1911 is designed to simply accept the longer 10mm Auto cartridge. Its dimensions are exactly calculated to supply correct headspacing and case help for the 10mm Auto spherical. The barrel’s chamber is meticulously machined to make sure secure and dependable operation. Making an attempt to make use of a cartridge that’s too quick, just like the .40 S&W, can upset this delicate steadiness.
The barrel is the guts of any firearm. It’s answerable for guiding the bullet downrange. The inside of the barrel, together with the chamber, is essential for the secure and environment friendly operation of any cartridge.

The extractor’s function is vital. It’s the small, spring-loaded element that hooks onto the rim of the cartridge case to tug it out of the chamber after firing. If the extractor would not have a agency grip on the case, the cartridge is not going to eject, and the gun will jam. This will happen with an incorrectly sized cartridge, or a cartridge within the incorrect caliber.
The journal serves as a vital hyperlink within the firearm. It feeds cartridges into the chamber for firing. The scale of the journal may cause points. The .40 S&W cartridge may not be correctly supported inside a 10mm journal. This will result in feeding malfunctions and different issues.
The Hazards of Mixing Ammo
Let’s delve into the potential hazards that would come up from making an attempt to fireside .40 S&W ammunition by way of your 10mm 1911. The dangers are to not be taken frivolously.
One of the crucial speedy potential points is the failure to extract. As talked about earlier, the extractor may not be capable of get grip on the shorter .40 S&W case. This will depart the spent casing caught within the chamber, inflicting a jam.
Improper headspacing can be a problem. It may result in misfires. With out correct headspacing, the firing pin may not strike the primer with adequate pressure to ignite the propellant. This will trigger the shooter to want to manually clear the weapon.
The hazard of case rupture or bulging is one other severe concern. If the .40 S&W case is just not absolutely supported within the 10mm chamber, the case will be overstressed, resulting in a doubtlessly catastrophic failure. This failure can lead to the discharge of high-pressure gasses and particles, which might trigger severe harm to the shooter. This might trigger extreme facial injury.
The potential for injury to the firearm can be an element. Repeatedly firing .40 S&W ammunition in a 10mm 1911 may topic the barrel, slide, and different elements to extreme stress, resulting in untimely put on or, finally, injury.
Various Options and Caveats
The one secure method to hearth .40 S&W ammunition in a 10mm 1911 is to have a professional gunsmith set up a conversion barrel, or to have a whole 10mm-to-.40S&W conversion equipment put in.
This conversion basically replaces the barrel with a barrel particularly chambered for the .40 S&W cartridge. Moreover, should you select to go this route, additionally, you will want magazines designed for the .40 S&W. Keep in mind that utilizing the flawed journal may cause feeding issues.
Basically, the fee related to a conversion barrel, in addition to the accompanying journal and different mandatory modifications, would probably come close to or exceed the price of shopping for a separate .40 S&W firearm.
