Last weekend, during a DTI Defensive Pistol Course on the East Coast, a student brought a 1911 pistol in 10mm Auto caliber.
10mm Auto had a brief following when it was first introduced in 1983. But, it never gained significant popularity, and there has been scant demand for the ammunition for at least the past thirty years.
Recently, it has garnered some popularity among handgun hunters. But, as a serious carry pistol, the 10mm has few adherents.
One of them was my student last weekend, but his enthusiasm for the caliber quickly withered as his $1,500.00 pistol failed to cycle time and again! Most common problem was failure to feed.
We cleaned and lubed it, but feeding issued continued.
In our, and his, frustration, we eventually put this student into a G19, which of course, ran fine for the duration.
We’ve seen a few other pistols in this caliber at our Courses, but not many, and I’ve never seen one that ran reliably.
The 10mm Auto is a long, straight-walled cartridge. It is essentially “designed to fail!”
Pistols chamberd for it usually have tight chambers (for accuracy, you know), which exacerbates the reliability issue.
As a hunting handgun, the 10mm Auto may have a place, so long as you’re not hunting anything dangerous!
As a pistol carried for serious purposes, it has few followers, as noted above.
One fewer after last weekend!
