I am new here but here for a distinct reason. I really hope some of you experienced folks can help me. I recently purchased a new 9mm 4" XD,went to the range only to have it go "click". The range master informed me that the firing pin spring was to weak to set off primers. My dealer ,begrudgingly gave me another new replacement pistol. The first time out ,it worked fine but the second time ,it too went "click" and was diagnosed with the same ailment as the first....a very weak firing pin spring. Supposedly the XD is a viable alternative to the Glock,but with better ergonomics and safties---which is why I bought it. Does this handgun suffer from maladies such as I have described? What do you think is the problem ? How may the problem be cured ? Right now it is being fixed at Springfield ---but is it really a reliable pistol for concealed carry ? Proper maintenance is not the problem as prior to and immediately after each range trip,the prescribed maintenance according to the manual was accomplished. Wolff Springs offers a firing pin spring with increased power and as I was told by them,"to cure just such problems". Help ! Did I buy a can of worms ? Can it become a reliable CCW ?
