Hiya Kelsw and thx for the thread, agree with above operators suggestions as well. My experience is that a shotgun is the HD first choice, as homes invasions involve several perps on avg. I'd go to LGS and try both,but which ever system your P-09 is where you already have muscle memory developed,so go with what ya know. Suppose considerations might include of your range allows drawing from a holster,as some forbid it. And subtle tho distinct differences if your P-09 is cocked and locked, one in the barrel hammer down,vs the latter with safety engaged. And I also have the preference of the cz decockers that you push down on, verses a tactical I owned that ya had to nudge it upwards,which felt unnatural. So do try to try it before ya buy it if possible. Be well.
