I did this once (breach load) on my glock 22 and 35 to see what they would do (using snap caps). The 22 did it no problem and extracted it cleanly. The 35 failed to lock up properly and I had to get a wooden dowel to tap out said snap cap. The 35 is older and has more rounds down the pipe than the 22. Used slingshot method when releasing slide.
Since that experience I learned my lesson.
