Capacity of the Px4 Storm

[Life During Wartime]

So for whatever reason, I thought the Beretta 9mm Px4 Storm was an 18+1. But since then I have seen on the maufacturer it is a 17+1. Was there an old model that had an extra bullet or maybe an aftermarket mag


I remembered, I may have also been thinking of the Beretta 90 Two, which also now has a 17+1.

To the best of my knowledge, PX4 has always been 17 + 1. Beretta also sells a 20 round mag for the PX4.
