I don't care for it compared to my XD, but then an XD is a true single-action trigger in a striker-fired pistol rather than a "safe action." I would say the Glock felt more gritty than spongy but that is just my opinion. My XD has some creep, but it is smoother in the creep and the break is as clean as a Glock, IMHO.
That said, I have no problems (and even prefer) with it compared to a unworked M&P or Sigma, or any of the DA/SA out there (i.e. Sig). It is still certainly good enough a production combat pistol.
