Bought it about 3 weeks ago. First trip to range - would jam the last bullet against roof of barrel. Did it with all ammo shot.
Returned to dealer - he suggested a new magazine. I also read about similar problems on other sites.
Noticed mine had rough machine marks inside barrel. With a dremel and a felt burr, tried to polish area - was only able to "smooth" rings - they still remained.
FF to today at range. ONLY 4 of 6 bullets in magazine would shoot then it would jam bullet in roof of barrel......................aaarrgh!
I guess it is hit or miss. You either get a jem or a lemon - mine was bitter!
Anyways, took it to the dealer today, in light of their "other" recall, it may be a long wait.
A couple of pics of one of the jammed bullets:
I will post results when I get mine back.
BTW, I renamed mine RUGER POS.
