having read a few forums and hearing a number of people , including myself, having feed and reliability problems with comanche length pistols i have found the fix. actually terry tussey told me about it and performed the fix on my pistol. on the comanche length pistols the slide does not come back far enough to allow the rounds in the magazine time to come up. the slide barely clears the back of the magazine. kind of like a 5 inch gun with a thick shock buff. he cut the frame rails back so the slide comes back as far as a 5 inch gun. after a trip back to baer and it still nosedived i went to terry tussey and he fixed it so it will feed with any of my mags and any ammo i have put in it. hope this helps.
