I'm using a Para 40 - not the tightest slide fit - I was wondering if heavier spring might give a better return to same zero.
Note: I get 26 rounds in my mags with room to load - I had two tubes cut and welded into one big stick. I should be okay most times with 26+1 even with a forced reload somewhere.
I like using my old Para 40 mags that hold 21 rounds. Still getting used to the ported shock and change in recoil from Limited.
