I have a P-01 Omega Urban Grey Suppressor Ready pistol. I just received some Mec-Gar CZ 75 Compact 9mm 10-round magazines and wanted to share how they fit in my P-01 (I have not taken them to the range yet for live fire).
First, here's a 16-round factory magazine (pinned to 10 rounds) that came with the gun:
Next is the 10-round Mec-Gar Compact Magazine
Here's a close-up the gap between the base plate and the well. It's almost like the gap of the factory magazine above.
Here's how the Mec-Gar 10-round compact magazine looks from the back when it's fully seated in the pistol.
Here's the factory magazine from the back.
Here's a pic of both mags. Factory is on the left and Mec-Gar Compact on the right.
The Mec-Gar compact magazine seats and ejects well in my P-01 Omega.
I installed the larger base plate of the factory mag on the Mec-Gar mag but the magazine did not seat in the pistol. The base plate also didn't lock to the base of the Mec-Gar mag.
Hope this helps folks looking for 10-round compact magazines.
