If you’ve seen our other semi-auto caliber tests, you might remember that we used sub-compact pistols with barrels around 3.5 inches while the G20 is a service-size handgun. Now, if I could just find one of those 10mm necked down to .40 I would really have something. We all hear about how terrific the 10mm is, but what if we put it to the test?

It didn’t always work when defeating obstacles like steel automobile bodies, auto glass, and surplus bullet proof vests worn by the up and coming motor bandits that used more force than finesse in their crimes. This comparison is a joke. * - indicates bullets that failed to retain an average of at least 85% of their initial weight. Would like to see what people think of the .357sig compared to these 2 rounds.

While both are overkill for deer broadside, a quartering shot or front-shot the deep penetration is useful if shooting from the front (I won’t take a shot with medium a handgun if the deer is facing directly away). In his article he shows the Clear Ballistics, in direct comparison testing it will perform just like the FBI gel spec but has a wider temperature range of performance and doesn't spoil like the real gelitin. So… Read more ». Likewise, it would be great to compare the rounds in longer barrel lengths. Some of their tactical people still use it.

Did I miss anything? Depending on who you ask, slight over-penetration is not always considered a deal-breaker, and these loads might still be worth considering for self-defense use. 3.) Perhaps the XTP loads are the only ones he could find with comparable weights. Then the bottom fell out from under the Ten—again. In the big picture, the 10mm will throw a slightly heavier bullet at the same speeds that the 357 will launch a lighter grain bullet. While newer and better bullets have been developed for the major semi-auto service calibers over the last few decades, ammo companies have devoted comparatively few R&D resources to designing bullets specifically intended to take advantage of 10mm’s capabilities. I have never liked the trigger on the Glocks even the improve versions still arnt great, Well I already have the 357 so I do believe I will purchase the new Springfield 1911 TRP™ 10MM – RMR®.

I have both and found that jacketed hollow points are only about 80% in every pistol I’ve ever owned except, for a heavily modified 1911. See more from Terril on youtube under Mark3smle. In most cases, the 4.6-inch barrel of the Glock 20 will boost a bullet’s velocity by an extra ~40-90 feet per second compared to a subcompact barrel that’s an inch shorter. We can see in this head-to-head that the 10mm retains a very slight advantage in terms of energy, but the 357’s overall longer bullet gives it the edge for penetrating power. I haven’t carried a .357 revolver in years myself but that would be my choice if I was going to do it. The clear plastic ‘gelatin” is NOT FBI protocol.

On paper with these comparable loads, the 10mm is slightly faster with an 81 feet per second advantage. Why not use a 10mm pistol with a shorter barrel to keep the test protocols more consistent? I do wound ballistic workshops for a living and shoot a lot of gelatin, made, calibration verified and shot to the FBI protocol. So no, I don’t hate semi-autos… Read more ». The .357 Magnum is a powerful cartridge, but in this case it takes a narrow 2nd place to the 10mm Auto. Don’t think it ever made it to general issue though.
