EBP Durability Testing – Drop Testing

The GRIP FORCE EBP is made from an engineer-grade polymer. The EBP is an injection-molded part made to precise standards. It is not 3D printed.

Throughout our product development, we have conducted various durability tests to ensure our product is suitable for hard-duty use.

Some of the testing has included the following;

Sample of three EBPs/magazines from production run: two G17 mags with EBPs and one G19 mag with an EBP.

The magazines were loaded to full capacity to make them as heavy as possible and subject them to the most significant free-fall drop impact forces. The tests were conducted by dropping each magazine from at least 4 feet high onto concrete and sometimes higher.

We dropped one G17 and one G19 magazine onto the five sides of the base pad (front, back, bottom, left, and right). Each EBP magazine was examined before and after each drop, under magnification and in bright light.

Our Team dropped two fully loaded EBP magazines (G17 & G19) from 4 feet onto concrete, 20 times each (5 times on each side). That did cause some slight scuffing on the base pads where they impacted, but no cracking or significant damage occurred.

We also dropped the G19 and G17 mags onto the cement from a height of 7' 2", and both landed without issue. We examined both EBP magazines under magnification in good lighting, and no cracking or significant damage was observed. Each of these two mags/base pads had been drop tested twenty times each (from at least 4 feet), and once each from 7' 2" high.

Cold Temperature - Drop Testing

Due to our MIL/LE customer base, we also conducted cold-temperature testing to ensure their suitability for extreme-duty use. We placed the third EBP (G17) fully loaded magazine in a freezer for just over 90 minutes. The freezer temperature was -17 degrees.

After 90 minutes, the G17 EBP magazine was removed from the freezer and immediately tested. It was dropped onto the concrete from a height of 4 feet. It was dropped a total of five times, once each on the bottom, left, right, front, and back sides. After a thorough examination, no failures were observed.

As with the first two magazines, this EBP magazine was checked under bright light (with magnification) to confirm there were no cracks or failures.

On a separate day, we used this same G17 EBP magazine for additional cold-temperature testing. We placed it in the freezer for over four hours (245 min total), and the temperature was -2 degrees.

Upon removal from the freezer, the EBP magazine was immediately drop-tested. It was dropped once on each side (five drops) for a total of 10 drops between the two cold-temperature test days. There were no issues, cracking, or damage other than slight surface marring at the impact sites.

These initial drop-test magazines performed so well that they were put into service and used as duty magazines. We will not sell any gear that we would not readily trust with our lives.

We continue to test the durability of our GRIP FORCE EBPs and strive to offer the best product we can.

Thank you.
