Giffroy,

One would not expect to have set back in the magazine from firing the pistol. If anything, one would expect the bullet to be "pulled" (increase the OAL) from firing as is sometimes seen in high caliber centerfire revolvers, and the locking the cylinder. The main problem with set back in a semi-auto is when the bullet strikes the feed ramp. If it does set back the bullet, and you are near/at max powder charge, then the chamber pressures can go quite high, and cause a problem/kaboom!!

If you are near/at max powder load, and not getting reliable toggle function, perhaps you might consider installing a lighter weight recoil spring.....Just a thought.
