I have a P01 omega & the width is too large for the CCP division- specifically with the ambi safety/ decockers its greater than 1 3/8 in (1.375") it measured over 1.4"
Disappointing, but regardless, am very happy with mine & will be shooting it this season (May even let Canuck44 fondle it next time he shows up south of the border )
According to another thread on here the P-01 Omega does fit the CCP box. The box is able to close even though the safety sticks out a bit.
The regular P-01 has a barrel length of 92,5 mm. Why not just buy it. The max. barrel length fir CCP Division is 111mm.
Your 4.4 inches equals 111.76 MM. The measurements mught vary from one gun to another depending on how accurate the company who makes the extended barrel is.
That is most likely what I will end up doing. However, I greatly prefer a longer barrel and a threaded barrel. Gives me more velocity, more options, and less muzzle blast, plus I feel it would not be any harder to conceal for me personally. I also like the sights that come with the threaded model.
If worse comes to worse I'll just be shooting it in SSP/ESP, but I would sure prefer to be able to use it in CCP!
