    Can I ask from where? I've had at least 2 suppliers not send emails, one of them has done it twice now - instead choosing to post something on social media. 

    Those website in-stock notifications are typically cron jobs that run periodically. If the cycle period is too long, say once every hour, the item goes in and out of stock before the job runs it never sees the item as in-stock and the emails don't go out. It's not typically a push notification, at least not in my experience.  If you want to get something that sells out fast you'll have to use a website tracker that checks every few minutes.

    IIRC the SRO is 25mm (wide) x 26mm (tall) 

    I have a spreadsheet with the window sizes of quite a few optics and I have the SRO at 22.61 mm X 24.89 mm.  I just went and measured the vertical height of one of my SROs and I'd say that's spot on.  So within 0.6mm if we're nitpicking.  It definitely isn't 26mm.  

  3. I'm looking forward to more info on this coming out.  Looks like it's aimed right at the SRO.

     

    Edit to add: The following site states the window dimensions are 1.1" (28 mm) x 0.87" (22 mm) and also has details on the reticle.

    Window Size: 1.1 × 0.87 in

     

    I believe that makes it as wide as the Romeo 1 Pro and as tall as the SRO.  That's approaching the size of the Romeo 3 Max but with an RMR footprint.

     

     

  4. The difference between the two will be insignificant so get the one that gives you the feels.  Shooting performance is 90% the shooter if not more so one or the other won't give you a noticeable advantage.

    Nothing wrong with your brass. Light strike issues tend to be about springs, firing pins and hardness of primers.

    And I agree with @HesedTech, it looks like a spring and/or lockup issue with the fire control system.

     

    Thank you both for the feedback.  I examined every part of the gun I could without luck.   I finally bought a spring testing kit from Atlas and the spring that came with my EGW ignition kit was supposed to be 17 lbs but actually measured more like 13 lbs.  I swapped it out for a Wolff 17 lb spring that actually measured 17 lbs and I haven't had a problem since.  I just wanted to make sure there wasn't something else going on.  This is a fairly middle-of-the-road load though so it would have surprised me.

    They all look fine to me as far as signs of pressure. Here is an extreme example of what over pressure can look like.

    Thank you both for the feedback.

     

     

  6. I'm hoping to get some input on how the primers look on my fired brass.  Particularly, is there a high pressure situation going on that could be causing a reliability issue? 

     

    I was dealing with what I estimated to be light strikes in a 1911 I was building.   When a few other people, who I'd consider more knowledgeable than me, saw the fired brass they were convinced the problem was coming from a high pressure situation that was causing the firing pin hole to clog up with metal bits and slow down the firing pin.  Eventually I was able to measure the hammer spring weight and found it was closer to 13 lbs rather than the 17 lbs it was labeled and swapping it out has since resolved the issue but I want to get some feedback and see if there is an issue here that just hasn't caught up to me yet.

     

    This load is 3.3gr of N320 under a 147gr Black Bullets projectile with an overall length of 1.140.  This brass came out of a double stack 1911 but I've shot thousands of rounds of this load through my Glocks and it looks the same and has never given me trouble.  You can see the primers are cratering a bit but I see no flattening.

     

    Any feedback is appreciated.  I'm not convinced that there's a high pressure issue here but I'm open to being wrong.

     

    First picture is this load out of the 1911 and one of my Glocks (gen 5).

    Second picture is some factory ammo out of the 1911.

    Third picture is more of this load out of the 1911.

  7. I got to try one of these first hand recently.  The window size is fantastic.  The refresh rate of the dot seemed to make it look scattered while firing rather than the dot streaking.  Is this normal?

     

    Also, is a dimensional print of the footprint available?

  8. Per the IDPA 2017 rule book:

     

    8.2.2.3 ESP Excluded Features and Modifications (Non-Inclusive list):
    A. Trigger shoes.

     

    And the 2022 Equipment Appendices.

     

    A.2.4 ESP Excluded Features and Modifications (Non-Inclusive list)
    A.2.4.1 Trigger shoes.

     

    I believe this makes the Timney Apex non-compliant for IDPA CO since it follows the ESP equipment rules.  

     

    That being said, I run an aftermarket shoe that's purely cosmetic on my Glocks and no one has said a thing.  I'd probably put a stock one back in if I went to a big match though.

    That is exactly why I won't use a Dawson, especially in a 70 series.  I prefer the Cheely.  It is not quite as long, but does the job.  The EGW is a very nice firing pin, but it is too short to use in some slides.

     

    I might have tried the Cheely but couldn't find it in stock anywhere at the time. 

     

    I might go back and test the EGW pin with a Wolff 17 or even 15 sitting to see how it performs now that I know the EGW 17 spring is really like a 13?

    Dawson has the best extended FP to their specs.

    It seems nice. It's long AF and actually protrudes into the chamber when the hammer is down. I can't see a scenario where there'd be a round in the chamber with a hammer down so it doesn't seem to be an issue.

    Do realize that just because the package may have said 17lb spring, it could have been a 15lb spring. I have seen it happen.  Sounds like something may be dragging. CCI is some of the hardest primers going also.

     

    To follow up on this, I couldn't find the compressed length to measure the main spring at and the gauge I bought only has a marking for measuring government length recoil springs.  I do have 15 and 19 lb Wolff main springs though and they both measure to the claimed weight at about the same length. 

     

    The spring that came in the EGW ignition kit that's in this gun is stated to be 17 lbs but measures at 13 lbs, maybe 14 if I'm being generous at the same length that the Wolffs measure to their stated weight.  

     

    So that was fun...

  12. I got a chance last night to test a new extended firing pin briefly and went through about 60 rounds without an issue.  I mistakenly assumed that the "O/S" in the EGW O/S Firing Pin that I originally put in the gun meant it was oversized or extended but that wasn't the case.  The new Dawson is significantly longer.

    Check the firing pin stop.  It may be the back of the firing pin is rubbing against it.

    Thanks.  I'll double check this.

    I actually took delivery of a spring pull gauge since I started this thread.  I haven't had the opportunity to measure the main spring yet but I'll report back if it's out of spec.  Thanks.

    One more question. Did you cut the chamber in the barrel? Is it possible it had excessive headspace?

    Just a thought. 

    When I finish reamed it I did have a chamber gauge on hand so it's within SAAMI spec as far as I know.

  14. I thought I'd follow up on this one more time to update on what I've tried and see if anyone had some further insight.

     

    I went to the range this weekend and tried some factory ammo and some of my reloads with primers set deeper (8-10 thou) than my previous batch without much luck.  The factory ammo (Speer) actually gave me 4 out of 22 light strikes so it's not looking like my amateur reloads are the problem.  I've put thousands of my current load (3.3g N320 under 147g, CCI primers) through my Glocks with a 4lb striker spring without a single light strike.

     

    I did play with the pencil test quite a bit and found the 17 and 19 lb main springs will shoot a pencil out of the barrel, both shoot it noticeably shorter than the Glocks with a 4lb striker spring.  

     

    I backed out the overtravel screw all the way to eliminate that as a possible issue.

     

    Below are a couple pics of some primers, including some of the failures to ignite that were shot with the 17 lb main spring.  To me they look light, particularly the failures, but I'm certainly no expert.  On another forum a few guys with more experienced than I seemed to be concerned that the primers were flowing and causing the firing pin tip to build up metal fragments and cause drag.  Again, I've been using this load in my Glocks without issue and I'm not seeing anything on the firing pin or feeling any drag when I articulate the pin by hand so it doesn't jump out as the obvious cause.

     

    I did swap out the 17 lb main spring for a 19 and ran through about 120 rounds (reloads and Speer) without a single issue though.  The consensus seems to be that the 17 lb should be enough, and some even use 15 lbs, so my concern is the 19 lb could just be masking an issue.

    Have you checked that the firing pin spring is inserted in the correct direction? If reversed, it can cause problems not allowing the firing pin to travel it's full distance.

    Yes, tight end to the back.  Thanks.

    Pencil test is taking the unloaded weapon, cocking the hammer, and placing a pencil in the barrel. Press the trigger and, hopefully, the pencil goes flying up into the air. 

     

    Eraser end pointing down. 

     

    It's a down and dirty  way to ensure your firing pin is doing what it's supposed to do. 

    Ok, gotcha.  I did assemble the pistol without the barrel to confirm the pin is coming through and it did seem to be going to full depth.  I'll give the pencil test a go to confirm for science though.  Thanks.

    Not to sound like a smart donkey but the primers are fully seated? I know I have this issue from time to time from me being lazy on the push stroke. 

    Thanks for the feedback.  I just checked from the stock I'm shooting and they look good.  I'm on an 1100 and it primes on the down stroke so it's hard to short stroke it.

  17. 1 hour ago, CHA-LEE said:

    If everything else is setup correctly, a 17lb hammer spring and an extended Fire Pin should set off any hardness primer. There is likely some other issue that is either keeping the hammer from hitting the back of the firing pin squarely, such as the lower barrel lugs not cut back far enough and the slide is sitting too far back compared to the hammer strike angle. Or the barrel lock up height is not right and the firing pin is hitting the outer edge instead of the middle. Look at the fired brass, is the primer strike in the middle or biased to one side? With the hammer decocked and resting against the back of the firing pin stop, what part of the hammer is touching the back of the firing pin stop or firing pin? The hammer should be touching the back of the firing pin long before it bottoms out on the back of the firing pin stop.

     

    I can take a look at it and tell you want I see if you want.

    I'll bring it with me Monday night and you can let me know how mediocre it is.  😆

     

    I looked at the hammer angle and the early wear on the firing pin stop seems to indicate the hammer is striking slightly past vertical.  

     

    Unfortunately I wasn't smart enough to bring home or photograph any of the brass from my test session.  I don't remember the primer strikes being significantly off center but they did look a bit light.

    Offset firing pin strikes shouldn't pose a problem unless they are way off toward the edge.  It's fairly common to not be exactly centered, particularly with a custom build and higher lockup on the barrel.  I would check the overtravel screw on the trigger and maybe back it out a bit to see if that makes a difference.  Also, check the firing pin hole to make sure there's not a burr or something in there.

    Thanks, I'll take a look at both of those items.

    OK, I'm going to be that guy that reminds you to check the stupid obvious stuff. Have you verified there's nothing in the firing pin channel that shouldn't be there? 

    That's ok because I'm the guy that would miss something obvious.  I did blow it out and clean it out with a cotton swab.  When I push the firing pin manually it doesn't feel like it's dragging to me.  

  18. I just got my new (first) build to the point that I could take it over to the range for a test fire.  It ran great except for an occasional light primer strike so I'm looking for some feedback on what it could be.

     

    It's a Jem/Cheeley build with mostly EGW internals and Wolff springs.  The main spring is 17 lbs, firing pin spring is Standard Power, extended firing pin, and the primers were CCI.

     

    I don't have a heavier main spring to try but I'm going to order one.  I've searched the forum and it seems like lots of people have no problem running 17 lbs and some even lower.

     

    Any feedback is appreciated.

    Log into your IDPA account right now, there is a survey on allowing AIWB holsters in IDPA. Personally I would love to be able to actually shoot the “concealed carry” game with actual concealed carry guns and gear. I hope they stop stepping on their own dick by disallowing it.

    Nice.  I'm surprised to see this come up.  I asked my area coordinator about AIWB and he replied "There is zero chance appendix will be allowed any time soon.".

     

    I won't hold my breath but until this changes IDPA is just USPSA with a bunch of extra stupid rules.
