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.

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.

That's for sure.

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.

Welcome. There are typically at least 2 matches every weekend to choose from.

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.

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. Thank you both for the feedback.

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.

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?

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.

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?

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.

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...

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.

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

This is still the original. The extended is "out for delivery" as I write this.

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.

Yes, tight end to the back. Thanks. 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.

Can you give me an explainer? I've never heard of it.

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.

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

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.

So sorry to hear. I never met him in person but he was very friendly when I communicated over PM. My condolences to his family.

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.
