  1. The group called "cz firearms owners group"
    it doesn't even come up in a search.


    I can see it... [emoji2375]

  2. Won’t be available in California except in private party transfer from an eligible purchaser, such as law enforcement. Then the “mark-up” doubles the price.
     
    226 SAOs go for $1900-2100 in California and are very hard to find.


    So if I bought one you’d pay me $1600 to $2K for it???

    Wow...

  3. The new 320 Legion has a tungsten matrix blended in the polymer making it significantly heavier than the standard 320 frames. Cool idea for a polymer competition gun.

    Now that’s worthy of researching!

    Neat!

    I am going through the same process right now with a Glock 22 that shoots way left.  I shoot all of my 9s and other 40s straight and most other people's Glocks straight but this one is definitely off and low round count to boot. 

    How were the OEM sights aligned?

  5. Ferritic Nitrocarburization is a surface conversion process and is a surface hardening process.

    I have some articles that I can email you.

    CeraKote is just a paint. It’s not very good compared to Melonite/Tuftride/Tenifer (all Nitrocarburization tradenames, btw). Parkerizing is not as durable or corrosion resistant, either.

    PVD coatings are thin film coatings and they are bonded but a small point load (a pointed nail) will cause the coating to fail.

    Glock is smart: the Melonite then use PVD (in this case some form of DLC) on top of their slide.

    That’s the best that I’m aware of at the moment.

  6. Nitrocarb is very tough. But it will wear if you're rough on gear or do a whole lot of draws from a kydex holster.
     
    PVD/CVD is a process not a type, whichever coating you choose will determine your results and color but many are tougher (and slicker) than nitrocarb.
     
    DLC is even tougher and slicker and comes in lots of pretty colors (duplex stainless looks amazing without being gaudy).
     
    Hard Chrome is also a good choice since unless you gouge the crap out of it you can just polish it out or re-beadblast for much less than a new coating.
     
    If you are very rough on your stuff, learn to cerakote and just repaint as needed.

    Actually, nitrocarburization is the tougher, harder, more durable more salt water corrosion resistant of the two.

    Putting DLC atop a nitrocarburized slide is the ticket.

  7. Is there a question here?

    There are lots of reasons why it may shoot left, but odds are it’s the shooter. Perhaps his sight has been drifted. Perhaps yours needs drifted. 99% or new shooters shoot Glocks left. Just a fact of the matter.

    That alone points to “Pistol” not necessarily “Person”.

    I conducted an experiment with two (2) Glock 43 pistols.

    One shot 3” left of POA at 5 yards/ offhand and from ransom rest.

    The other one shot 1” left of POA offhand and from a rest.

    So...

    (1) I switched upper assemblies

    (2) I switched only barrels.

    (2) I switched only the slides.

    The problem followed the lower assembly.

    I assume it is the locking blocks.

    Wherever the rear sights are drifted when the pistol is brand spanking New is where they NEED to be to be point of aim: point of impact.

    I used to mechanically center them and then scratch my head.

    I now know so I hand select them based upon where the rear sight is located in the dovetail.

    I’ve found Gen 5 triggers to be remarkably consistent so it’s less critical compared to, say, Gen 3 and, to some extent. Gen 4 triggers.

    Sold that left-shooting pistol with full disclosure to a guy who was adamant it was me. I was glad as Hell to rod myself of that craptastic plastic and began paying much closer attention to such things as the position of the
    Rear Sight in the dovetail.

    I have planned on doing another experiment with purchased locking blocks to see what differences they may make (essentially checking dimensional tolerances or variability) but it would require much more equipment and effort than I’m willing to invest and it’s not MY problem; it’s Glock’s problem.

  8. For those that have run your pistols hard for a few years, are you finding that one is holding up better than another?  I’m looking at a few custom builds a they both run different finishes.

    “Nitride” is far too generic a term.

    PVD (Physical Vapor Deposition) coatings come in many, many varieties of which W DLC is but one. There’s also TiAlN (Titanium Aluminum Nitride) and others.

    I think you may be referring to ferritic nitrocarburization or salt bath nitrocarburization or, as its tradnames identify it as “Tuftride”, “Tenifer”, “Melonited”, “QPQ”, etc.

    PVD is a COATING

    The latter process is a SURFACE CONVERSION PROCESS.

    I would coat a Melonited pistol with a PVD coating - like Glock has done with the 19X and Gen 5 pistols.

    I cannot think of a more durable surface than that.

  9. I picked up a newer DVC in .40 and immediately noticed that the scalloping at the rear of the slide does not provide as much grip as the slots machined on the Edge slides.  When racking the slide during an unloaded start, I use the overhand technique, however even with this I have to grip the slide much harder and more carefully than I do with my Edge.
     
    Has anyone else encountered this?  Any way to fix aside from grip tape or machining the slide?

    I’d have the slide bead blasted to the surface roughness you desire then have it coated with a PVD coating.

  10. i have 2  new  tso with  same sloppy machining signs  on lower lug  and damaged barrel bushings . dealer ask from cz to send replacement bushings only and they refused.
    cz dealer sent pic. to cz and the answer was that it's  all  O.K.  [emoji3] 
    this was last "custom "  sloppy fit guns from cz that ours club will ever order.



    I would collect the photos and all other evidence and place it on their FB page.

    They’ll respond.

    Trust me.

  11. Any feedback thusfar on the quality of goods coming out of the Kansas City facility?
     
    Not to put them down or anything, but I rarely trust any new pistol (ahem Sig P365) or new iteration of a pistol (ahem Glock gen4).
     
    Given the total lack of optics plates, I'm considering getting a Czech made P10-F and just getting it milled? Seems like it's about a $80 price differential on average, so you wouldn't be out too much extra cash.

    Why not use the P-10C?

    You no longer need sight radius...

  12. What *I* would do if I were to manufacture bolts I’d make them print holding the longitudinal length to a very low tolerance.

    For example, the print may call out 35mm +0.1mm/-0.15mm (I’m making this up).

    I’d insure that the dimensions are nominally 35mm and the variance WITHIN what’s allowable.

    In other words, QUALITY CONTROL & QUALITY ASSURANCE.

    Now... what DO THEY DO?

    I cannot imagine them deviating from what I’ve outlayed.

    It would be interesting to measure, say, 10 examples of Colt, BCM, LMT, etc., bolts with statistical analysis.

    That would make a nice technical article.

  13. Check out Todd Jarrett on grip:
     

     
     
    I took a class from him and grip is a big deal to him. He made some changes in my grip that were really subtle but helped a lot. 
     
    Additionally you will find all off the top shooters work on weak/support hand grip strength. Why? Because in rapid shooting grip strength is how we control our guns for the follow up shots.
     
    In one of my first USPSA matches I was on a squad with Henning and after watching me shoot he came up and squeezed my forearm with his support hand and said, "grip it like that." He has a strong left hand.
     
    Additionally you will read a whole lot about the grips on the gun itself. Again look at top USPA shooters and they have really aggressive textured grips. People add "board tape", "cheese grader" grips, very aggressive stippling or similar. The goal is to hold on really tight.
     
    Get a couple of those "Captain Crush" grip trainers (not those cheap Walmart easy ones) and get your support hand beefed up.[emoji2135]

  14. With much better customer support. 


    You’ve got me curious...

    What is SF Customer Support like?

    I said “SF” because... “if it’s good enough for...”

    I tangentially knew some guys who worked at Crane and they felt that the SF cans were the best. They stated that they were not the lightest or quietest but flash suppression, minimal shot dispersion and durability is where their product(s) shine.

    I do not possess one so my experience of ownership is all naught.

  15. I have a Sig P226 and the Magazine Safety Spring has broken twice.  When it is broken the mags won't load or if it breaks with a mag in it they will not drop out, and the pistol will not fire.  The slide works but the trigger will not fire.  I know this Safety Spring is a feature that California insists on being installed to sell here in this state.
     
    My question is.  Has anyone else had this problem?  Since this is the second time it has happened I want to know the cause.  Is it a factory defect or am I doing something wrong.
     
    I want to compliment Sig on their quick response and willingness to fix it right away.
     

    Can you “de-neuter” it?

  16. ATEI in the Detroit Metro Area would be my suggestion. It's owned by an admitted friend but I only befriended him at a shooting class and that was before I was even remotely interested in his products.

     

    SUPERB workmanship - I've got a Glock 19 with RMR mounted by him and he should soon be offering W DLC coating through IonBond as well.

     

    Check out the website and give him a call.

  17. Well, I have run into another issue. My 13 yr old cannot rack the slide on the P-07 with the dot mounted. He used to be able to come over the top of the slide and it improved his grip on the small CZ slide. Do y'all think it would be a problem if he used the front serrations and the back of his hand pressed on the sight to help with leverage? I'm not comfortable with it, but maybe someone here can assure me he isn't going to put enough stress on the sight or mount to break something, or knock it loose.

    I recently picked up a lightly used Gen5 Glock with an ATEI-mounted Trijicon RMR. I *thought* I'd have to send it back to ATEI for slide serrations until I got the pistol in hand.

    Grab the slide like you always did. The optic will touch the palm of your hand but as stated - if it can handle the recoil of the pistol when being fired it will have handle you handling it to cock the pistol.

  18. Interesting perspective from everyone. I didn't see if anybody talked about with eye sight problems, (near sided, far sided, contacts or glasses)whether they use a dot or still prefer iron sights.

    I'm nearsighted and I'm trying an RMR on a pistol now. I also have astigmatism and considering eye surgery so...
