Roger that.
5.7 is my go to round for a whole host of reasons.
The only legitimate downside of what you've listed is the price of the weapon. Ammunition is very reasonable and available albeit by online sources.
There is a real issue to be aware of though. This particular round is VERY sensitive to changes in bullet weight. Point of aim vs. point of impact can vary up to two inches between 27 grain vs. 40 grain loads...AT SEVEN YARDS!
Any general change of ammunition should be followed by a sight adjustment.
That said, I don't know any other pistol where I wouldn't feel outgunned by an AK ;)
Thanks for the info. I would like to try one but my days of buying things I want but don’t need have passed.
There is a long list of guns I once had and wish I had again. A shorter list of guns I never had but would like to try out is still pretty long.
