Fully agree on replacing springs. The recoil spring is the most important in your type og malfunction, so replace it first. When you take the gun appart, make sure you check the condition of the leaf spring (behind the grip safety) and main spring (inside the mains pring housing-the arched thing). Sometime gunk accumulates there, and while this is not relevant to FTF, it can cause light primer strikes etc.
While you at ir, check the barel to frame fit, sear-trigger-disconnector arrangement and grip safety function. This is 70 series gun, so the firing pin should be very easy to remove. Change that spring too and clean the firing pin chanel.
There are total of 5 springs in the 1911, not counting the magasine spring. It should take you about 30 minutes to change them all. Very simple. One thing, before you take them out of the frame, make sure you note how sear and disconnector fit together. They are also small funny looking parts, don't loose them.
