Handled the gun for like an hour at decay of nations it is pretty sick the stroke is reminiscent of an old hammer but more solid. The mags are well thought out. The straight ones are 9 rnd FS compatible. It is also compatible with all the other mags. The 45. frame is pretty comfy I couldn't complain. The grip frame is one piece. The barrel is spyder threaded but has this twistlock adapter that allows to switch between ammo types.
