I'm still learning the best way for "me" to pull the P320 trigger. 1911s are easy. Like you, I've always been a fan of VV N320; especially with the 147g bullets. At the recommendation of Luke/KKM, I bought some N330 to test with the 124/125g JHPs. It definitely tightened up the groups a bit....... Sent the MAX to TSA for his competition package. Have to say it's as close to a 1911 trigger as ANY striker fired pistol I've had in my hands! We actually discussed that issue prior to him doing the work........... 1911's are easy??? YES! Like you, I've also had a love affair with the 1911/2011 platform for right at 50 years! I enjoy their fire control system more than any other!!! BTW: this is that same "match load" I bench rested yesterday in the new LO pistol: Link to comment Share on other sites More sharing options...
RangerTrace Posted May 25, 2023 Author Share Posted May 25, 2023 Well, Maybe I need to try some N330. Is it just as soft as N320? How many grains are you using for the 124s? Link to comment Share on other sites More sharing options...

IMO, yes it's just as soft...........a little slower burn rate but about the same energy......... https://www.vihtavuori.com/powders/n300-powders/ 4.7g @ 1.080" which yielded a 135-136PF IIRC. This fell right in line with KKM's recommendation....... Try it..........you'll like it! Link to comment Share on other sites More sharing options...

I did discover that my new GGI P320 has a slower barrel that the GGI P320 Lockwood. Both 4.7". I'm probably lucky I made PF last weekend at Texas State.

I may have already mentioned it...........but Luke at KKM said I should be in the 4.7g - 4.8g for my 5" KKM barrel to come into it's "sweet spot".......... Good luck!

RangerTrace Posted June 5, 2023 Author Share Posted June 5, 2023 4.8 grains of N330 under an RMR 124 grain TC Matchwinner to 1.125" seems to be the ticket. This is a 15 shot group fired from a rest at 25 yards. If you exclude the 3 shooter errors, they made it inside a 1.5" circle. For any kind of P320, I'm very happy with this group.

I might pickup some VV330 at some point, I already use RMR 124 FMJ and 124 MPR/JHP, but I suspect the group has as much to do with the shooter as with the ammo.

Thank you, I am certainly trying to learn the P320 trigger and the dot at the same time. The other N320 load was certainly accurate enough for IDPA/USPSA matches, but if there was a powder out there that could tightening things up a bit, I had to try. So, I was happy enough about these results that I loaded 1000 rounds of it yesterday to cover Area 4 and Kentucky State. Link to comment Share on other sites More sharing options...
RangerTrace Posted June 10, 2023 Author Share Posted June 10, 2023 I shot Area 4 today and started with the newer Modern Classic slide pistol. All started well, but by the 5th o r 6th stage, I had 4 light strikes. I switched to the Lockwood and went the rest of the match without a light strike. This ammo is case gauged and carefully inspected for high or even semi-high primers. The ammo is perfect. I use CCI SPP and the Lockwood has never failed on checked ammo. I'm waiting on a response from Bruce, but I need a quick fix before KY State next week. I assume I can just swap strikers between the two pistols and it should correct the issue? FWIW, I LOVE the small TXG grip module and the barrel/slide combo is a tack driver. For whatever reason, it shoots about 50 FPS slower (than the Lockwood) as well and feels softer!!

Is there any significant design differences between the modern classic and the Lockwood slides? I was under the impression that the Lockwood was essentially the same; perhaps slicked up a bit with some nice checkering differences. Not true?

I've never had a problem swapping P320 strikers back and forth between multiple P320s. However with mass produced components I could certainly see a striker that worked fine with this gun but was marginal with that one.

RangerTrace Posted June 10, 2023 Author Share Posted June 10, 2023 Bruce had me check for primer flow. There was a tiny bit in both pistols. I have not examined my brass since I settled on 4.8 grains of N330, but it only made 132PF at area 4, so it's not overly hot. Link to comment Share on other sites More sharing options...
RangerTrace Posted June 10, 2023 Author Share Posted June 10, 2023 The small group is from the Lockwood pistol, the larger group is from the Modern Classic. No light strikes this morning out of 50 rounds. Link to comment Share on other sites More sharing options...
