Officer acp dual recoil springs.

[iblong]

Mornning guys/Gals need some input please.
This weekend I was getting my Colt mark IV 80 series officer ready for fall carry,I shot 100 flawless standard preasure loads through it ran perfect.
I then ran some warm loads 6.3gr unique -xtp 230gr 1.230 they run an average of 860 fps out of the officer and about 920 out of the Gov.model,recoil seems to be to brisk for the single 22lb wolf springs failure to feeds,failures to bat.ect.put the old dual spring back in and flawless again.If I go back to standard loads it worked fine with the Wolf 22lb.I have mabe 4-500 runds on this spring,I cant seem to locate dual springs for it.
The heaviest spring I can find is a 24lb.Will the 2lb spring make much of a difference.These failures are a bit unsettling as Ive never had any issues with this pistol in the three years its been carried.
Thanks,Bob.
