Externally, the EPM1 has also been updated significantly.  As with the original EPM and all PTS polymer products, the EPM1 shell is made with Dupont Zytel® polymer which makes it extremely durable and strong.  Another carryover feature is the continuous mag well guide to reduce snagging when drawing from or inserting into pouches or the rifle mag well.  Our signature EP texture has been implemented onto the shell to give the magazine a positive texture for better grip and tactile feel.  The texture along the spines have been changed to ridges for even more positive tactility and allows the EPM1 to be compatible with the Magpul Maglink® Coupler.
