I have a P30L, P30, and an HK45. The triggers as they come from the factory have a long reset. I noticed quite a difference compared to my Glocks, VP9s, 1911s. I remember once I was shooting the HK45 in a class and I did not let the trigger out all the way to reset. So I sent them to Gray Guns and had the shortened reset package. Now I can shoot them completely interchangeably with the other guns and not experience any issues.
Another thing that I had done to the P 30, the P 30L, and the HK45 is to have the groove removed in the lower inside of the trigger guard. That used to whack my finger during recoil and be uncomfortable. Interestingly, the VP nine has the same group but is not a problem. This is because the slide and rear grip of the VP nine is different and is higher to allow me to grip the gun higher up in a changes dynamics of of where my finger is during recoil.
