Are you sure they are Gen 2 magazines (tan follewer ) ? Gen 1 mags can be iffy in some gen 2/pcc guns....

I cleaned the gun including the gas tappet which had a caked on layer of carbon.
I swapped the bolt carrier group with my father's new (less than 500 rounds) MPX pistol. My bolt carrier group ran just fine in his gun (no stovepipes), my gun with his bolt carrier group still stovepipes.
Did you also clean the carbon out of the expansion chamber in the gas plug? as that fills up the piston starts movement sooner, and therefor extraction is started while the brass is still expanded against the chamber walls causing the extractor to slip off the rim before the case hits the ejector and clears the action..... simple test move the newer gas plug to the problem gun.... an additional consideration is the extractor spring will have been over stressed up to this point and a rebuild would be a good idea...

Has anyone tried to undercut the trigger guard on the legion grip? It feels a little funny with how flat it is on the support hand.
Undercut triggerguard & beavertail.. thinned the front strap & transitions to the sides ( Front & Rear) then stippled

PCC is 2nd or 3 most shot division in AZ for the last 2 years.... last 2 matches # 1 and tie for #2 :

I use mine more than my laser now ... tight ports that you would have to bury yourself In to use the primary...plus reduced bore offset on really close upper A only targes..

Maybe you're right. The Government always knows best doesn't it.
I have milatary friends that have lost their sight from lasers ...." eye safe "only means that you will look away/ close your eyes before you do damage, that's why a slightly defused splash back can be more dangerous than a direct view.. you can play Russian roulette with your eyesight, but I wont RO, run the pad or stay in a bay with someone using one.

The 5mw is what is deemed as eye safe( no protective laser safety glasses) any thing over that is dangerous in direct view and IN SPLASH BACK OFF OF THINGS...their is a thred on the PCC area that some videos were posted of the lasers burning/melting stuff..I was a laser safety officer when I was in the milatary,wont stay in a bay if someone is using one over the 5MW limit..I don't care whet th sticker says i can tell...bottom line if it is brighter than the 206 it is a risk..

Do you prefer stippling to silicon carbide? I just bought the stuff to do my own since I've done a decent amount of stippling on other pistols I was wanting to try something different.
Prefer to reduce ( adjust the natural sight index) and stipple...

My buddy is getting one for his. I think Springer sells them as semi fitted and should drop in with minimal work if any.
Simi fit will need some work on the hood... have a 2011 HEXTAC for IDPA I'm doing for a friend that
I need to finish first.. CO is a 2020 projectnfo me

I finally shot the Legion UPPER today and confirmed that the LCI notch does leave a stripe of debris on the lens. The difference is significant.
After 100 rounds of factory ammo (Blazer Brass). Hope you can see the stripe right above the notch. I applied a piece of tape to the lens to show how much debris there was on the lens.
I would remove what is on the lens with a piece of tape after each stage but it will be primarily a back up.
yea LCI is gonna be a long term problem... I opted to do a Bar-Sto barrel without a LCI....

Hello: I just have pro grip on my hands and grip for now. I am right at 44.27ozs so I may have to to give up something so I can put some tape or silicon carbide on it. I have not seen anyone yet texture the tungsten grip with an iron yet. The rain did let up but the ground was a little soupy. Tear down it was not raining. Thanks, Eric
Grip Undercut Front & Rear, Shaved down and stippled... better than grip tape.

So there is a Proam style match in Pima this sunday and Im trying to go.
USPSA in Tucson is on its death bed... lots of canceled matches, low turn out... that Proam is only because the USPSA normally on that day is canceled ( all Pima USPSA are canceled for all of September) ... I am doing the 1.5 hr drive to Rio for the Saturday match...

Does the new bolt carrier design retro fit to older guns?
Nolan
Yes... I have the newest carrier, spring guide and buffer in my oldest gun.

I have been hoping for a SD3G that worked in the MPX and they offer me a 2 stage trigger with a price gouge to boot. I'll pass.
Never had a bit of issue with my Eclipse so I'm sticking where I'm at.
Been running SD3G's in all 3 of my MPX's since 2017.....

For me based on my military experience with the Colt SMG’s (blow back 9mm) I knew that I wanted a locked breach gun and the advantages it offers. Some key points
· I was able to replicate the malfunctions in my #2 gun that has none of the gouging in the upper
· I was able to eliminate the malfunctions in all 3 guns by restricting the gas and beefing up the extractor tension ( same thing you do in an over gassed AR)
· I believe the loose ejector contributed to the gouging in the upper, combined with the high carrier velocity and the sharp edge on the spring guide dovetail. The new competition carrier and spring guide eliminates this that’s why I bought it for the #1 gun with the gouging in the upper
· I have seen similar / worse wear issues in other piston systems (SCAR, HK416) that are steel parts in an aluminum receiver. The linear operation of a Direct Impingement AR is really a wonderful thing
· The hole down the center of the gas plug is critical, as this fouls up with carbon, Bullet coating or lead the volume is reduced and starts the piston moving sooner in the cycle time ( i.e. over gassing)
· I balance the ammo (155-162 PF) with the gas system, recoil spring rate and comp to get all 3 working together …. Same thing you do with an OPEN gun
· I could have gotten a new competition MPX when I bought my #3 gun so I could push the #1 gun down to practice/beater status… however based on all my trouble shooting and fixes I felt the last thing the MPX needed was more dwell time ( lounger barrel same gas port location)

That's what I'm trying. Do you have the grooves in the receiver races, too?
I had zero luck with Sig:
- wanted the whole gun shipped on my dime ( over 1 year old)
- would void any warranty if it had "after market parts" .. i was unwilling to un-pin @ weld the MBX comp and re-pin & weld the stock flash hider back on...
- stated the expected service life was 25K so I should count my self lucky that I got 30K
I got them to sell me the latest updated carrier, spring gide and buffer and I keep an eye on the ejector to make sure it is not loose again. the groves line up with the part of the spring guide that dovetails in to the carrier ..
once I went down the over gassed / to fast a powder burn rate + week extractor springs trouble shooting path all 3 of mine run 100% until the extractor spring wares down ( 7-10K or so) ... and I go 4 times as long with 50 % less build up on the cleanings
-
Check to see if the ejector is tight in the upper receiver....one of mine came loose at some point and also gouged the upper..it was the dovetail interface of the spring guide digging in ...I have since changed that upper over to the new competition carrier and spring guide

Agree the RO bit is faster but frankly I have seen a variance in responses from handing a flag to the RO which seems to correlate closely to how they feel about PCC as a division and I just don't feel like dealing with it. Never an issue at 3-gun matches though.
you would think that PCC being the #2 or #3 largest division in all of the level 2&3 matches in AZ for the last 18 months, the haters would start to get over it... If they got their wish and PCC went away in to their own stand alone sport that would be a 30% ish drop in attendance at the now Pistol only matches...

I have a small dump pouch on my belt on my week side behind my mag pouch:
- drop the first mag in it when I head to the line
- drop the flag in it when I grab the first mag to load
- drop any used mag (s) and chambered round in it & pull the flag back out
my mags on my belt are only used for reloads, every thing used on a stage is in the dump pouch to be cleaned and reloaded at the end of the stage....

Factory ammo is usually loaded with a bulk canister powder specifically spec’d for that use which isn’t available to aftermarket reloaders.
Guarentee everything from federal is canister and not available to reloaders.. charge weight will also vary lot to lot as presser is the primary data point used for lot acceptance...

I think you can still buy the old style plug at ILWT. I’ll try the soaking for a few days to see if that works first.
Early Gen 2 had the "complex" plug that was replaced with the "open" .. the "open" ( .114" -.117" is what I have seen) is the only available part from Sig.. If you want to play with the restricted plugs ILWT is the source .0520" &.0469".
My #1 & #2 guns use the .0469" my #3 is a.0520".... BUT I also have the MBX Comp's that increases Back pressure, like a suppressor and I use speer 115gr TMJ's @ 1400 FPS , federal XM9001 115gr JHP @1425FPS or reloaded 115JHP's @ 1410 FPS.....

Soooo.....would you explain what the factory achieved buy going to the open style gas plug please.
eliminated customer complaints on the system not running on crap ammo and / or loaded with fast powders ( anything aluminum cased, American Eagle, anything steel cased, WW wight box (exception for 124 NATO wight box load) ). My #1 gun has 30K on it, my #2 has 18K on it and my #3 has 5K on it... I can induce a malfunction in any one of them by:
- running to big of a gas plug for the ammo velocity/presser/powder burn rate
- letting the expansion chamber area of the gas plug get reduced in volume with carbon/lead build up ( ie early unlock)
- letting the extractor springs get worn out
Running the restricted gas I can go 2K In between cleanings and have less build up than I used to see on 300 rounds with the open plug's..

If I understand the plugs correctly, the small size plugs allow more of the gas to vent out with less obstruction. Perhaps that's enough force/heat to keep 'em cleaner?
No, the smaller size plug lets less gas in to the system over a lounger time and restricts the excess flow after unlock. The piston and plug act as an expansion chamber for the gas when the correct volume is reached the piston moves back creating a larger expansion chamber until the piston passes the vent holes.

Installed mine yesterday.. didn't like the "competition" return spring reset. Swapped in the "carry" return spring and kept the light sear springs for a 3 1/8 LB pull with a reset I can live with.
