So long as your pistol has a Series 80 style hammer this is normal. It shouldn't have a negative impact on the safety of the pistol in any case. Double check your sear by first removing the magazine and clearing the chamber, then lock the slide to the rear. Now set the pistol on a hard surface (i.e. table, counter, etc.) on it's right side. Without holding onto the pistol, bump the slide release lever to disengage it from the slide so that the slide goes into battery. The hammer should not fall. If it does, take the pistol to a competent gunsmith and have the sear replaced before returning it to service or carrying it loaded again. If you are still unsure of the pistol, take it to a competent gunsmith and have it looked over.
