Interesting. I special-ordered the CA version, with some standard magazines, just for the added safety features. I have no need to be able to fire the gun if there isn't a magazine in it and I like the idea of being able to tell, by feel, if there is a round in the chamber.

Also, for my wife, who has a little difficulty in racking the slide, I can leave the gun loaded and cocked, but with the magazine not fully in. All she has to do is push the magazine home and the gun is ready to fire. It's very safe otherwise.

Anyhow, others have posted suggestions for problems similar to yours, inability to remove the slide after doing internal mods. Not sure where to find them.

Have you been able to see anything by looking up the magwell?
