I finally picked up my CPX-2 last night!!! At the lgs they had both the newer and older versions of the slide and mag release. My wife didn't like the newer style ( I agree it was a bit harder to release slide). So we got the older style.
One of the mags loaded about 8 rounds decently. The other only 6. After taking them apart they were both void of oil. I'm gonna give them a light coat of oil and let them sit a while.
I'll let y'all know how the first trip to range turns out.
