@kneelingatlas Do you still feel the CM needs popple holes with the new comp?

 

"Need" is a funny word, adding holes will almost always make an Open gun shoot flatter, but it also means more powder and more blast, so it's certainly a matter of preference.  Here's a video my friend took of me shooting it this morning.  I plan to do a slow mo video when I can find a place to set it up.

Tested the new comp yesterday and its a good upgrade from the factory comp.

The gun shoots flatter and is less nose heavy.

 

Going to experiment with more powder to see if it can utilise it better than the original comp.

What all would i need to / have done to utilize this comp with a 75b 40 cal slide that's had the fpb removed ?

 

Remove barrel bushing

taper ream slide to comp bushing angle

fit barrel of correct length and threading to slide

Install and alignment ream comp

install on tac sport/sp01/or 75b frame

Enjoy!

did I miss something?

The OD of the bushing in slides made for 14mm OD barrels is significantly larger that that of this comp.

 

You could leave the busing in place, cut off the cone and use this comp as a bull-barrel style on a TS barrel cut to length.

What would the barrel oal need to be?

And the thread engagement length and pitch?

I have about 1000 rounds through the new comp. It works well. I had to chase the threads of the factory barrel (as suggested by Kneelingatlas) to get it to fit. 

 

Forgive me, I’m not a native english speaker: what is “chase the threads”?
