Hello: Since guns sales are in the toilet right now I am not sure it is a good time to raise prices? Lots of options in the 1911 market if you want a 9mm or a 45acp but not many if you want a 40 S&W. Thanks, Eric
Trojan in .40 Cal is discontinued... the ONLY .40 Cal Single Stack available now from STI is the DVC Classic... Makes no sense to me, have to wonder what is happening @ STI lately.

That Holosun 510c has the same latch in the mount as the Sig Romeo 4B that I sent back twice for failure to stay locked while firing.

Been using a Romeo3 on my MPX ... Then destroyed it. So while it's out @ SIG for replacement, I slapped a Holosun 510c on. I'm starting to really like it and potentially more durable w it's shroud. Can do circle, dot, or circledot reticle and has sleep function as well as solar
One on our AR9
commonsense in the industry is 99.5% that the Sig and the Holosun are made in the same factory.... just saying.

Just an FYI - reaming a 9mm to 38 super/supercomp is not a great way to go. The dimensions at the base of 9mm is larger so your brass will bulge. If you want a 38 super/supercomp get a barrel that was reamed for it (with a 38 super Nonte reamer) and then adjust or change your extractor to run super or supercomp.
So you are calling out Schumann, STI ,KKM and any other manufacturer that sells a short chambered .355 barrel as not knowing what they are doing.. That pretty much leave the Schumann AET and BarSto finish chambered barrels as the only barrels that are correct using your logic.

yes A finish reamer has Zero effect on the rear of the chamber when used:
"reaming a 9mm to 38 super/supercomp is not a great way to go. The dimensions at the base of 9mm is larger so your brass will bulge"
The rear chamber dimension is set by the manufacturer. typicality it is set to the low end of 9x19 ( .0391 -.007 = .384) .38 supper is .384 -.006 = .378
The tolerances of 9x19 9x23 and .38 Super over lap that is why the a short chambered .355 barrel is sold and works.

I have all 3 lengths:
3ea 170mm
2ea 155mm
3ea 140mm
what I use and when depends on the stage breakdown and my plan. If I could only buy 3 mags to start I would do:
1ea 170mm
2ea 155mm
Barney off one of the 155's that becomes your "oh shit" mag in position 3 use the 170 and the other 155 in whatever order the stage breakdown and your plan indicates.
140's are good for classifiers and the rare stage where you shoot 8-12 then reload. If I am shooting moor than 12 I am starting with a bigger mag

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
Add Leupold LCO to that list.

I have 2 identical guns and a third that I am currently doing some experimentation with. If it works out I will do a twin later this year and have 2 sets of twins.

Couldn't get Gen 1's to run 100% in my Gen 2. lucked in to a even trade on hear with a guy needing Gen1's

I am happy to duplicate a factory NATO/ EURO spec load..Gives me the same feel and I have the option of using factory for big matches. additionally from whare I buy my factory 9mm it is $40 more per 1k than reloading, if I need the brass... I can't justify my time to buy once fired and load it when I need a brass restocking..

I went to N340 when VV stopped importing N330 and never went back. IME N340 and WAP ( Silhouette ) are vary close. I will stay with the N340 because I have 12 LB left over from my Limited days.

I don't know - seems like an awful lot of people here on BE like TruBors
Yes.. but neither of us have visibility on the sales VS production capacity #'s that STI uses to make their decisions on.
-
- Or sales are week vs the DVC open and dosn't justify using production capacity
- Or everybody hacking the True-Bore slides up to reduce weight means that the state of the market has moved past the True-Bore configuration

Thanks Kevin. Yep I will be at Rio. 5 stages of steel is impossible to say no to. :-) I am tending to agree with you that the MPX has less dot movement at higher PF. Not sure why because we aren't running comps but it is what it is. Plus I am really tired of clearing the jams I started getting when I dropped the PF down from my higher "break in" load.
It is down to cycle length, cycle time, port presser and dwell time. If you are short stroking the system you will have the carrier mass in counter recoil effecting the gun when it closes, because it did not dissipate the correct amount of energy in to:
- full spring compression (cycle length)
- the receiver buffer stop (cycle time)
Being similar to an AR system with a brass deflector if your brass is not going to 2 o'clock you are short stroking.

Kevin, i am still working a load up for my MPX and while I get the logic of a slower burning powder your load is just over 161 PF which raises a couple of follow up questions. Do you just prefer to shoot at that high a PF or is that as low as you can go reliably? I get reliable function at @ 150PF with E3 and it is a weeeeeeee bit faster than 340. (still feels softer than 130 PF in a blowback). I guess the two salient questions are A Can you get down to 130PF with slower powder and B Is 130PF even the right goal to pursue?
I found that in my 16" gun my 125gr Montana Gould JHP @ 1290fps (5.6gr N340) 161 PF was softer with less sight movement than the same bullet @ 1160 fps (5.4gr 3N37) 145 PF. The 3N37 load was initially 1090 fps 136 PF and not reliable brass fell out the ejection port at your feet and had massive sight movement in recoil and counter recoil.
IMO a 130 PF goal is not where I want to be, my development goals were:
- Reliablity
- Fast cycling withe the least amount of sight movement
- Ability to match an available commercial spec load for:
- Flyaway matches
- Brass replenishment
- Cycle time close to an AR or an Open pistol
Speer 124gr TMJ or Geco European spec 124gr both hit the 1280-1325fps range and meet my goals on 1&2.
I did arrive at this load vary easy I had about 1K of the 3N37 load that was run by a friend when my reloading set up was torn down for construction of my new reloading space,I had to shorten the OAL and tighten up the crimp for the MPX and that put it up to 145PF. The other load of 5.6gr N340 was the same charge I used in my .40 6" limited gun. When I looked it up an it was within the range for 9MM so I just ran with it, thought if it worked it was one less step converting that press from 9mm to .40 or back.
If the 150PF load meets your goals it should be good to go. If you are a @ Rio this Sunday I will give you a handful of the 161PF loads.

something is binding the trigger bow, things to check:
2011 grip screws if loose it will cause the trigger bow to bind
Over travel adjustment, as in not enough.
Over all fit of the trigger bow and shoe, if it is to loose movement can be nonlinear and cause it to bind.
Vertical movement of the rear of the trigger bow, the part the disconnect rids on if this has excessive movement it causes the disconnect and sear to bind

Yea I just did the preorder.

Key words being " for me" . I get .08 -.10 splits pretty easily with an AR or the MPX and as fast as it sounding like a Double fire on a close wide open target.
I run my 9mm 3gun load from my 5" and 6" 2011's 125gr MG JHP 5.6gr N340 1290 fps in the MPX , 1220 in the 6" and 1190 fps in the 5". My point being a locked breach gas operated system has difrent ammo requirements than a blowback unlocked system. I agree you can play around with weight, springs and loads to optimize that blowback system. However that also narrows the operating band on it also, would you want to put a NATO spec or Open 9 round in to that blowback system optimized for a Production minor load with a small charge of fast powder? I wouldn't.
For me one of the selling points of PCC and my MPX is I don't have to fly with reloads. I can buy NATO / Euro spec 9mm on site at a flyaway match that preform like my reloads.

i hear
16 minutes ago, surgdog said:I certainly agree with your statement but I have used my recipe for my handguns and don't want to change or have a different load for just one gun. If I can accomplish that by opening the port a bit it would be worth it.
As far as the OP original question about an opinion between the two its just my personal experience that as far as obtaining one of the two and going to shoot the CZ is a more competition ready platform IMO. I love the MPX. It is cool and a blast to shoot. It's just taking more tweaking than the CZ and for almost twice the money I would think it would shoot anything fed to it. But as you rightly point out it is a different operating system and as also pointed out in a different thread on here somewhere Sig probably didn't design it for competition. Once I get it going I can't wait to shoot it in completion with my handloads.
I hear you, I just think of the MPX as the PCC equivalent of an open or limited gun that you tune the loads to exploit the advantages the system has to offer. I would never consider running a blowback gun in PCC it is just to slow of a cycle time compared to an AR, open or limited gun for me.
As a side note I saw a guy have a out of battery detonation with a CZ a few weeks ago in a match his trigger finger out ran the operating system.

The MPX is a gas system it needs gas pressure and dwell time to function. For a Gen 2 gun you just need to pick your powders from the correct burn rate category (N340, HS6, WSF) . Don't try to use a small charge of fast powder like in a production minor pistol it will not generate either gas pressure or dwell time in to the operating system..

The MPX is a gas operated system and has different operating requirements than a recoil or blowback system. Your load is the issue with the MPX. it is a gas system it needs gas pressure and dwell time to function, a small charge of fast powder is not generating either gas pressure or dwell time in to the operating system. A slower burn rate powder would help (N340, HS6, WSF).

.198 is standard for castings. Most custom builders us a billet and or hardened .200.
.197 is undersized, if the lugs were fit correctly to a .197 then you may have a tighter lock up on the bigger diameter or you may have a interference in the lock up. going to a smaller diameter from what was used for the initial lock up can cause issues with link breakage.
End result is if you change from what the gun was built with the following needs to be checked:
