A recoil spring is not real hard or expensive to change,or maybe some zippier ammo.

I have a Commander clone I just did some work on.I put a stock rate 18 lb spring in it.Same problem you are having.Bought new Colt mags and plus 10% wolf mag springs.That helped a lot,but its not 100%.I'm about to order a 17 lb and 16 lb spring.

The ammo at this point is WW white box Walmart promo ammo.

When I try or load some stiffer ammo,I can go back to 18 lbs.
