I have seven Para double stack 1911s including a 45 ACP and 40 S&W warthog and 45 ACP Long slide SuperHawg. All function without any problems except ONE mag won't reliable feed the SuperHawg but works in 2 other 45 ACP 1911s.

I agree that if they work (mags & guns) you are happy. If things don't work, life gets frustrating. Ammo can be a problem. 230 jacketed RN worked fine, one gun would not feed lead 230 RN. All will feed 200 gr lead SWC with OAL = 1.250" and taper crimp at case mouth = 0.469" . The shoulder of the SWC is about 0.010" to 0.020" out of the case.
