Just got back from the range - did the test with the various ammo with the new P-11 - everything worked great - it ate 95 grain frangible flat nose, 115 FMJ and hollowpoints and also my favorite 147 grain hollowpoints. It was easy to keep in the CM at 10 yards even rapid fire, but like other poster said, it does have a snap to it and after 200 rounds my hand had had enough...
but like I said, the Bersa Thunder 9 UC was a great shooting gun, just bigger and heavier than I wanted to carry, but was fun to shoot for extended sessions.
