about when will p99 fully break in?

[lyricsdad]

Any other .40 SW owners out there.. especially w/ the walther p99. When did your p99 fully break in? When I have a full magazine, loaded it is very difficult to rack the slide. When does this become easier? My first pistol was the p22 so I am used to a really easy slide lol. this p99 was like night and day. So when does it loosen up? I have 412 rounds put through mine so far.
