Further Information


PTS EPM 1 Magazines require the very strong internal spring to be bedded in before use. To do this, simply fill the magazines using a standard speed loader (avoid using an ODIN or similar crank wound loader) and empty them again by pulling the BB retainer on the top of the magazine backwards with the feed/fill port pointed in a safe direction, preferably back into your BB bottle. Do this 2-3 times for each magazine before the initial use.
