So I haven't had the compact, but I carried the 85 (basically an ambidextrous 75) daily for 15 years until 2 years ago, when I replaced it with a 75 sp01 (also called cz 75 shadow). It's my daily carry and my ipsc standard division competition gun (same applies to the 85).I also had a friend who carried the 75 compact for a few years. All I can say about the 75s is that they're real workhorses.I carried my 85 in the service and while on reserve duty, and it delivered like the US post: through mud and rain and sleet and sand. Mainly mud and sand. The newer shadow is slightly more sensitive, (no clumps in my mud please), but somehow managed to keep the same grip and feel, only give better accuracy and speed. And truth be told I'm doing a lot less time in the mud these days. I might be getting a bit long in the tooth for that... I haven't fired the walther nearly enough to form a good comparison, but fwiw I'll give the cz´s a big thumbs up.
