The grip is from an AXG Pro. I'll put together a more thorough list of parts after testing the 4.7" barrel/slide setup.

 

Nice. I love the AXG Pro more than the X5 setup actually, (here's mine), plus it can double as my EDC. Well, I don't have a photo small enough to upload.

Observations from the Open Major P320.

• 14# recoil spring had better return than 12#.
• I've never shot a more accurate 25 yard group at speed. Roughly a softball with 0.5s cadence.
• Dawson sight pusher does not make a good sight racker, it cracked after a mag. This was due to a combination of using aluminum and drilling the through holes with not enough material clearance. I bought some 0.375" aluminum bar stock as a temporary fix. I prefer to stay with Al for now due to ease of machining with my hand tools.
• The compensator is not aggressive enough for the ammo load. I might create my own using CFD analysis in the future. I have some thoughts about using a PCC compensator.
• Two failures to ignite out of a 120 round batch due to using CCI 550 Small Magnum Pistol Primers. Switched to CCI 500 to see if the issue persists.

Current ammo recipe:

• Precision Delta V2 124 gr JHP
• 6.9 gr Winchester AutoComp
• 1.13 +/- 0.005 OAL
• CCI 500
• ? PF, I'm estimating 172-176 based off of feel, will chrono this weekend.

 

The gun works surprisingly well.

 

So far, I've unintentionally spent over $7K on this project (yes, I feel as stupid as this gun looks). However, it should cost less than $2700 including the Sig Romeo3 Max optic. If the gun remains functional after 10K or so rounds, then I think it will be a very good entry level option for those who are open major curious.

 

Sorry if I missed it before but is your 320 an X5? Appreciate all your knowledge transfers!

Brilliant breakthrough, similar to point of diminishing returns. Or like how you're better at something after you've taken a break. Your subconscious is still analyzing and improving the process ready to execute it better next time. Though there is a point where the break is too long.

Very happy with my Otto Noize Barriers - with the foam tips - as the plastic flanged ones don't do squat. Also very good are the 3rd party Comply foam tips.

[Henning +6 Base Pad - Question]

I ordered directly from HenningShop.com and got the new Grams followers and springs - flawless so far in my 17 +6 base pads. Just got them earlier this week though and only been through one USPSA match (about 100 rounds over the three mags).
