johnhhuber Posted May 24, 2013 Share Posted May 24, 2013 I just bought my first two M&Ps (5" and 4" pro series 9mm) for IDPA and USPSA competition. I have shot 1911s for years and this is my first real jump into this type of pistol. Questions... 1 - What springs do I need to change out and at what recommended frequency? (my 1911s I changed firing pin spring and recoil spring every 2K rounds etc.) 2 - What parts do I need to keep in my repair kit? I have heard the strikers are prone to break...what else? Thanks!
