Here are the Raven9 and FX9.
The Raven9 has the following:
Davinci Comp
Faxon 10" Tapered Barrel
KynSHOT PCC Hydraulic Buffer
Tinney Competition Trigger
Primary Arms SLx MD 3MOA Microdot
Lockhart Magwell
FX9
TandemKross Buffer
FX9 10" Upper
6oz Buffer (Presently testing)
SIG Romeo5
Techwell Magwell
The Raven9 is more expensive and wears more upgrades. Build quality (fit and finish) is substantially better then the FX9.
The major drawbacks of my Raven9 are/were:
1. The lack of a feed ramp. Flat point bullets have yet to feed reliably in the Raven9,
2. I and others have experienced broken firing pins. Lockhart indicated to me the faulty pins had heat treating issue and they have since received a new batch of pins. I have not tried them nor have I had any further firing pins fail on me.
The major drawbacks of my FX9 are/were:
1. My FX9 suffered from headspace issues resulting in several out of battery ignitions and swollen cases with both the 18.5" and 10" barreled uppers. Since resolved under warranty. NOTE: I have since discovered felt or any cloth cut thick enough to fill in the cutout notch on the Glock style mags glued in place with Krazy glue works better than trying to glue plastic to plastic. I even tried paper wich works once soaked in glue. Either way the mags now lift the bolt catch lever and the bolt locks back every time now on the FX9.
2. My FX9 continues to have 100% lock back issues after the last round. Wolverine did bend the lock back arm and it works some times on some of the mags. If you fill in the notch on the follower of Glock OEM or AM mags my gun will lock back the bolt 100% of the time. Call it what you want but Freedom have an issue that may have or may not have been resolved. I would insult your intelligence if I repeated their explanation for this failure. SHK marked Korean 10/32 mags work the best in my FX9.
Here is a picture of a modified mag. You have to shape your glued in part. I used a piece of plastic and Krazy glue. It is the red part in the photo before shaping.

With the comps both PCC's shoot dead flat. With the hydraulic buffer the Raven9 felt recoil is very much like a .22LR. Both comps cost about the same. I believe the Davinci Comp is the better of the two. I ordered both from the Manufacturer. The Raven9 has an improved trigger installed with an hydraulic buffer and better optic will be my primary competition gun.
For the record and because my shooting buddies know this, I shoot both PCC's about the same....not well. With the red forearm, red Ruger Hat, 511 Vest and Levi Shorts/Jeans I do look awesome though. Ya just cant buy talent but god knows I tried. :>)
