There seems to be quite a bit of confusion at Remington at the moment. The HTP, or high terminal performance, ammunition line is still relatively new. I'm not really sure if this line replaces the Express line, or is being offered in addition to Express. The Remington website isn't much help. This particular load is listed as a .357 Magnum on the HTP ammunition information page. Regardless, a 115 grain +P load from any of the big 4 ammunition makers gets my attention because it's a rarity. All the other big ammunition makers catalog a 115 standard pressure 9mm load or two, but Remington is unique with their 115 grain +P load.
For this test, I decided to try this new ammo out in a new handgun. I opted for the Glock 43 with a 3.4 inch barrel length.

I really don't have much to add other than to express my disappointment in the performance of this load. Remington publishes a 1250 feet per second velocity for this load when fired from a 4 inch barrel. Our measured velocity was less with our 3.4" barrel, which is perfectly acceptable and expected. Unfortunately, this load didn't perform well in the heavy clothing tests when velocities dropped below 1200 feet per second. This load may perform well when fired from a longer barrel. For use in the Glock 43, or other subcompact 9mm handguns, there are better options available.

Terminal performance in all other media will show different results. It is up to each individual to make their own personal decision on which specific ammunition to use for their needs. It's also critically important to test any ammo in YOUR SPECIFIC FIREARM before relying on it for any purpose.
Ammunition labeled as +P or +P+ should only be used in firearms that have been certified by the manufacturer as safe for the additional pressures generated by these ammunition types.
