What is causing this? This happens about 33% of the time. When I rack the slide to simulate the recoil, it jams. Like a 3rd/4th-type malfunction.
It doesn't seem to matter whether I rack the slide quickly, or if I do it more slowly. Ultimately I have to eject the magazine, tip the gun on its right side (in the air), and work the action until it comes loose.
pulling the slide to the rear forcefully does not simulate recoil. your not strong enough or fast enough to do that. it happens in almost all weapons that use inertia to aid in the ejection of spent casings. this happens from time to time when i use snap caps with my walther ppk/s in .22LR my bersas my SA 1911-A1 also with my 1944 Ithaca 1911-A1 and with my sig 220 and all the conversion kits i have for the previous.
I talked to someone at the range about it tonight. He said that the gun isn't meant to necessarily extract and eject a round with a bullet still in it. Obviously the Snap Cap has a "bullet" still attached when the gun goes to eject it.
