What makes this particular gun special is that pistol comes with two types of magazines. One has a baseplate that is flush with the bottom of the Compact grip frame and has a capacity of 17 cartridges, the other is a full-size capacity magazine with the XDM Gear Mag X-Tension that not only gives it a 25-round capacity, but also transforms the XDM pistol into a full-size XDM 3.8 configuration.
The XDM came with 2 magazines, one 17 and one 25 compared to the 13 and 19 round magazine from the real steal version. There were also two Mould-Tru backstraps (sized small and large), and 3 magazine X-Tensions so you can convert regular length magazines to XDM Compact configuration.
Just to let you know, the fps may differ but 280 fps should be a accurate result!
