This is the better ESP gun it has alighted slide that is IDPA legal :

Just finished up the changes and shot a couple of matches.

Were you trying for a load just over minor with a 147GR? The 147gr JHP 9MM loads were developed for a narrow operating band of performance. Try increasing your 147 gr velocity to 1050 -1070 FPS.

Yes the light eliminates the square trigger guard issue.. I have found that kydex for the Springfield Operator full rail with light works well for light failed 2011's.

Robar... I prefer NP3/ NP3 Plus but the have Roguard and Poly- T2 also. I have guns done in the mid 1990's with lots of rounds down range.

Keep in mind that the A5 doesn't function the same as a standard buffer their is a lot more going on than just cycle length with the A5:
1. Deceleration of the weights in recoil
2. Unloading of weights in closing/
3. Elimination of carrier bounce

Will you use that variable for USPSA matches too?
So far I have used:
Sig Romeo 4B ( sent back under warranty)
Trijicon MRO
Trijicon TR21 1.25-4X Green triangle retical
Burris MTAC 1-4X Balistic CQ retical
I am staying with the MTAC 1-4X, I have used the magnification on:
CM 99-40 Partial People Eaters
CM 99-09 Long Range Standards
And on a stage ware shooter had a choice of using 3 different boxes for a target array ( 20yd, 50yd or 75yd). The Balistic CQ recital works the best for me across all the target engagement ranges we have in USPSA, and allows me to sometimes run a stage different than I could with just a dot.

in my MPX I run :
125Gr MG JHP
5.4Gr N340
1290 fps161PF

Geissele B-GRF. 3K so far, no issues.

Is there any sort of general consensus on dot size for this application?
Thinking that I would assemble an open div rifle that I would also use as a "precision rifle", so optic would be something like a 3-9 or 4-12/16 or some such.
I recently picked up $300 work of Cmore gift cards from the FN 3 gun match (thanks FN and Cmore) so I'm thinking an RTS2 would be interesting. They come in 3, 6, and 8 MOA.
Based on the below, and the numbers primarily at the 50yd distances, I was thinking a 6MOA dot would work out nice.
thanks

Sig would be good if it would hold up.. I just don't see it based on the poor build quality so far.. the MTAC is working the best so far 2 (USPSA) HOA'S and 1 all steel HOA so far

I have pulled off 2 HOA' S out of the 5 matches shot so far....

The problem exists in all of the devisions.. production is just the worst case.
Maybe this deserves another thread...
Well they haven't done that for Production. The top GM's are shooting above the 100% HHF in some cases 15-20% above.What would serve as a better way to start out classifying shooters in the new division?
I guess that's my issue. I get that there are flaws in using the Open hhf's for classifying PCC shooters, but I dont have a better solution at this time. Perhaps in a year or so they can reset the PCC hhf's with actual PCC scores, but until they have that data, what would you suggest as an alternative?
As an alternative I would have set a 6 mouth collection period and base HHF factors off of actual data and then correlated that in to HHF's for the remaining stages.
But why wouldnt they adjust HHF's for production? Seems like having the numbers off like that (long-term) would create numerous "paper" GM's, etc...?

For sure, using Open HHFs is not going to be equitable in the long-term... too many of the current classifiers have mandatory reloads, which are the Achilles Heel of the PCC. Presumably this question will be addressed when the Powers That Be have enough scores that they can correlate existing handgun HHFs to PCC HHFs at a comparable shooter performance level.
In the meantime, my guess is that the GrandBaggers will be checking out the classifier stage at the start of each match, and only elect to run PCC if there is a no-reload classifier, preferably with longer-distances thrown in too.
Add week hand strings in on that also .. week shoulder both hands on gun is advantage PCC..

No they should drop off fast:
B: This score is more than 5% below the minimum score for your current class and cannot be used. Please note that you may have scores from your initial classification that are lower than more recent scores that are flagged B. This is because all scores regardless of percentage are used to determine your initial classification; however, after you have earned your initial classification only scores that are at higher than 5% below the minimum score for your class can be used. For example, for a C-class member, only scores that are higher than 35% will be used.
I had a C class % in Open with an A card for years because I just didn't shoot Open that much, only took a few months to get an A percentage last year when I retired from Limited. However PCC is a bit different it will be interesting to see just how things progress.
-
Makes no difference, everyone could put in four .001% PCC classifiers and you will still get classified one class below your current highest pistol class. So it is A for me in PCC irregardless of how well I shoot the first four classifiers.

Bellvill Tactical Research Khyber Mountain Hybrid, zero break in time best boot have ever used

Are you running a thumb rest as well? The best thing to flatten a gun out is ditch the thumb rest and learn a solid grip. You will be amazed.
100% agree.. lot of people comment on how flat my open and limited guns shoot for me. I have used a unbroken ( thumb under the safty) isometric tension grip my whole life.

Thanks guys! I bought an MPX Carbine today! Gunna run some factory Speer Lawman through it on Friday and try an MRO from LaRue! It's actually lighter than I thought it would feel. But I still wish the handguards were a tad bit smaller but I am used to NSR/MI rails. Can't wait to take it out to a PCC match!
T
Congrats! I'm very happy with mine - i went matchy/matchy on optic and got a SIG ROMEO 4C, and so far so good (normally I use Aimpoint or Leupold)
BTW, if you feel you need to spend more, Lancer is supposed to have a carbon fiber front handguard that will replace the factory metal one. No timeline that I can tell, but when I pinged customer support, they said they added me to a list for notification.
My Sig ROMEO 4B went back to SIG for warranty, QD mount shifts forward and backward under recoil, if you tighten it down to stop that the latch pops open under recoil and the sight falls off.

Thanks for the info! I just ordered some Gen2 mags in case I bought a Carbine. Have you had any issues running the courses with the longer barrel? What stock are you using? Have you tried any factory ammo and had any issues? Thanks!I am running the 16" MPX carbine, had some initial issues with cycling 125gr @ 1040fps in Gen 1 magazines only, load was ok in Gen 2 magazines. I bumped up the load to 1160 and switched to using Gen 2 mags only, this load works but feels like it may have a slight short stroke resulting in a a small sight dip when the bolt closes. I have since settled on a 1290 fps load because that is the same powder and charge weight I run for limited.

I don't have any issues with the lounger barrel, but I never was a bury your self in a port type of pistol shooter anyway.
Gun was sent with the wrong stock (retractable), still wating on the side folder from Sig. Currently running the KAK knuckle and a ACS stock.
No factory ammo, I load MG 125gr JHP's.

I am currently trying several sight and reticle sizes every match seeing what will work best, so far I have used:
MRO with 2 MOA dot
Romeo 4B 2 MOA dot and 50 MOA ring
Next match it is a TR21 Green triangle 1.25-4X

Gen 2 have a tan follower and lounger feed lips... Gen 1 is a black follower.
Solfest load that will cycle in mpx gen 2

I found that in my 16" gun my 125gr Montana Gould JHP @ 1290fps (5.6gr N340) was softer than the same bullet @ 1160 fps (5.4gr 3N37). I am convinced you can short cycle this system and induce more recoil and counter recoil bounce, while still ejecting and feeding. The 3N37 load was initially 1090 fps and not reliable brass fell out the ejection port at your feet. I reduced the OAL an gave it a bit more crimp to get it to 1160fps. Any NATO/ European spec 124gr 9X19 ammo is going to be 1280-1325fps. The ability to simply buy good factory ammo for a flyaway major match instead of having to bring hand loads on an airline is one of the reasons I like PCC. Another reason is if Iam low on brass I simply buy a case of good NATO/ European spec 124gr 9X19 ammo that matches my reloads.
