Years later I learned you could use a Wolff extra power(11lbs)magazine spring for the full size 7 round mags in the 6 round Colt officers mags.These helped a lot so the mag spring could keep up with the high slide velocity of these short guns.
These little guns need a little more TLC than their 5" counterparts. I change my recoil spring every 500 rounds and firing pin spring 1k. Mag springs when they show signs of loosing their oomph to keep up.
Sounds like a classic example of recoil spring bind to me.
That's not the fun's fault. That's an operator error by using a recoil spring that was too long.
