I guess some have better luck than others...both of mine feed, fire and eject every time with high quality ammo, as did the first one I owned that I foolishly sold to buy the Covert version. I still carry mine daily, fire it every couple of months, and would never part with it...if para never comes through it will still be a collector's piece someday, similar to my 1917 Savage .32 auto.
I have a Solo that is not, unfortunately, very certain to feed a round predictably; can't carry it altho I do love to shoot it...nice sights, good feel, quite accurate at close range. My cousin has a Solo that he cherishes...we went to his range and fired at 10 yard plates...he actually did better with my R9 than with his Solo (he missed one plate). They were equally accurate in my hands (I missed one with each...old eyes). The R9 is still by far the easiest and most comfortable pocket and/or IWB carry of any 9mm IMO.
