    Any update on how it’s doing?

    not good. My friend sent the gun back to Sig, they put in a new barrel. He tried a heavier recoil spring with a modified magazine with the front surface trimmed off via dremel to make it look more like an STI mag. nose dives. I recommend he get rid of it at this point, it seems that the Sig P320 does not seem to function well in .40. We have both spent way too much time and effort trying to get the thing to work with all sorts of different ammo.

  2.  
    The two guns (Wilson and Nighthawk) that I have used them with have a tendency to cause the slide to lock-back during firing. The mag springs seem weak when compared to other springs.
    I don't think the mags will cause lock back during firing. I think it's a random occurrence of the slide stop wiggling. Regarding springs... You should replace them every so often I think...

  3. We spent a few hours magazine tuning last night. We did several things:

    1. Compared 9mm magazines. Sig 320 9mm measured .350, Tanfo 9mm .357, STI Spec per Dawson tuning .350-.355. The 9mm Sig magazines work, and are in range of other magazines and specs.
    2. Compared .40 magazines. Glock .40 .377 back, .385 front. Sig .40 .370 front and back, STI Spec per Dawson tuning .380-.385. The Sig .40 mags were significantly tighter than a referenced Glock magazine and the STI tune specs.
    3. Tuned the Sig magazines, with .375 back, .383 front. Initial hand feeding out of the mag indicated that there was a little more clearance from the front of the magazine tube and less hang-ups occurred when hand unloading the magazine. I still actually had the bullet nose get stuck, potentially due to the second round getting pushed forward and being pointed down to begin with.
    4. Plan is to test out the new tune. If that doesn't work, we may cut away material from the front of a magazine to make it resemble STI or MBX mags.
  4. Factory length ammo ... the biggest offender is Federal Syntech, 205 gr. I have the 14 round mags with TTI +5 bases and their springs, but stock follower. The issue doesn't have anything to do with how many rounds are loaded though, it can happen with 10, 5, 2, etc. It actually can be seen when unloading the mags by hand. It happens on all 4 mags too. I know grams has followers (and springs) ... not sure if that would help here though. I can try to post some pictures at some point.
    Maybe it's worth trying the grams springs and followers. I use them in all of my 2011 mags.

  5. A friend of mine recently bought a Sig P320 in 40 cal to pair with his x5 parts - tungsten grip module, fire control group, etc.. to shoot Limited with. It seems to work alright, other than he has a fair amount of jams.  Further inspection reveals that it seems that the rounds may be getting hung up on the front portion of the mag, not clearing the tube. Either the bullet itself gets stuck, or the rim of the case. This occurs both with aftermarket basepads and springs, and the original factory magazine baseplate and spring. Has anyone seen this issue and resolved it? It seems that the front of the tube needs to be filed down a little in my opinion, but I wanted to ask first if anyone else has figured this one out. 

     

    Thanks!

  6. a friend of mine is doing this. he bought the tungsten grip module for his X5, and then more recently bought a refurbished 320 in 40. it works well other than the fact that the .40 mags have an issue with rounds not clearing the front of the magazine, which I plan to start a new thread about if I can't find one.

  7. Limited minor with whatever gear you have is the easiest way to start the sport. Load up the mags, fewer reloads, get used to the mechanics. Shoot a few matches and make a more informed and personal preference decision then. I don't agree with newbies shooting production first. They are going to get wrecked in the scores regardless, so make it more simple with fewer reloads and stage planning extra thinking.

  8. I own a CK limited gun from 2014 that runs well.

    I recently bought a CK single stack in 40 that I needed to buy a Dawson mag catch and use only Berry's RN to get it to feed 100%.

    Bobby K will answer messages if you need help with a CK.

    I bought an Atlas Titan last spring and ran it all season. It is by far my nicest firearm. Excellent fit and finish, smooth operation, great grip (PT Evo), and a killer trigger.

    I personally know and have shot local matches in NH with Adam. He always responds to questions and is helpful in making sure your gear (even other guns) will run as reliable as possible.

  9. As the title says, I'm interested in how to tell the difference between these two.. i am probably going to pick up a used open blaster this weekend.. I'd like to be able to figure this out..

     

    I do actually have the two extractors, as I previously bought an open gun in 38 super and put a 9/38SC one in.. but I'm not sure if I can immediately tell the difference..

  10. I have loaded over 40k total on my 650, and close to 20k in .40. Recently, I have been getting cases that were jammed up sliding into station 1, either getting hung up at the back of the "slide" or just popping out completely of the track.  Has anyone else ever encountered this in any caliber, and if so, what was your fix?  I noticed that the station 1 locator had wear on it and Dillon sent me a new part, but after replacing that part, I'm still experiencing the issue..

    I cant speak for anyone else, but I would not have recently purchased a limited/or open gun had this been in effect.  PO always seemed like a waste of time to me till now, unfortunately I wont be trying it for a while, because of the other guns I purchased.  I wish USPSA would have  a little more consistency in the rules of the new divisions, then I might have a better idea of where to spend my money.  I guess for now I will just enjoy shooting open.


    You will love it! Open is amazingly fun!

  12. It is right now, but obviously things can change quickly.

    looks like the gun weight issue is up for discussion, so imagine an Edge with a red dot.





    If I'm reading this correctly I bet Limited will die a slow death.

     

    I mean, shooting major, with a dot,  and reloading about the same as open? People will love it.


    You guys might want to freshen up on the rule book.. CO scored minor like production and an Edge will never be production legal.
    Also, Limited will probably always be a very popular division..

  13. Anybody load TG under coated 200s?

    I Chrono'd some, out of a CK Arms limited gun with KKM barrel, .400 200gr Ibejiheads, loaded to 1.20", on a 53 degrees F day.

    3.6gr TG = 166.5 PF

    3.8gr TG = 173.5 PF

    4.0gr TG = 178.2 PF

    Thanks Earth!

    Did they shoot pretty decent?

    They shot OK, but I had better options.. I chose to go with Clays at about 3.55gr for 169PF - warning - only load long with Clays at major (in case you have not seen this warning yet)

  14. I just did the Harbor Freight glass bead approach, got lots of lead and carbon out of a Bedell comp, est 10k+ rounds through from previous owner. Worked great, but kind of dulled the finish a little.
