What do you think the 170mm would hold 25-27?
That would be a game changer for LE duty mags too...right now reliability of the extensions is "questioned" (notice I didn't say questionable) and as such we are not allowed to carry them.
If Magpul's 170mm 9mm mags prove to run like all Magpul mags before them do....well then - that could be a game changer in a gunfight. The more rounds you can dispense without needing to reload the better IMHO.
