Pros: easy to shoot, fast followup
probably decent penetration in fmj config
cons: expensive to buy, and expensive to shoot - you will probably not get as much range time beacuse of the cost
The ' defeating body armor ' ammo isn't readily available, and the round probably doesn't have much energy/ velocity left after defeating the armor anyways
hard to find ammo
small wound channel in fmj, shallow penetration in v-max loading
If you want one or have one then enjoy it. I think it is a neat idea for a plinker/ fun gun but not an answer to any SD questions that haven't already been addressed with other firearm choices.
