I have a thread in the Ammo sub-forum about something similar, same pistol too. Here it is.
Mine fed 230gr. Gold Dot HP at the range yesterday just fine whereas before yesterday all four of my mags (2x seven round factory mags, 2x eight round Chip McCormick mags) were having trouble stripping the Gold Dots from capacity as the mag springs appeared to be too strong or not fully broken in yet; however, now that I've put another 170 FMJ rounds on top of 80 previously fired FMJ rounds it will now feed the the Gold Dots when properly seated by slapping the back of the mag against my hand.
Only trouble I had yesterday were four or five rounds FMJ Winchester Whitebox that were weak and failed to chamber the next round completely after ejecting the previously fired cartridge as well as leaving the slide out of battery due to the squib. My gun just hates WWB but loves Remington UMC, so I guess it all depends on your gun.
