  1. What was used for lubrication ? Due to tight fitting I usually use oil on rails and barrell and small amount of light grease on lugs and slide stop. When it is warm thicker oil is used (to stay on slide and barrell longer) when it is cold light oil. Check if gun is assembled properly and if nothing rubs "more than it should". As slides starts to feels sticky does the gun still works as it should (fully cycles, ejects brass properly, etc) ?
  2. So after 1st match with new optics the impression is great ! I was initially concerned with the additionall weight, unscrewing the mount, brass ejection, dot dancing like crazy due to weight etc but.....nothing like that happened After mounting it as any other optic with red loctite (put some nail enamel check marks on the heads of the screws to see if it is unscrewing) after roughly 700 rounds I can say this setup works as expected and is awsome ! Although it is big due to window size mostly and sits a little bit higher than my previously mounted red dot plus it is a little bit heavier, those are not issues in real life at all and the benefits for me are: - really easy to find the dot even with one/weak hand shooting from some unusuall positions. - transitions are much easier as you can see the dot moving to the target you will be shootiong earlier so less time wasted trying to "find it" - ejection pattern is fixed after small modification/tuning of ejector - so zero stovepipes / ejection problems so far. - all the benefits of different reticles (I shoot mostly the circle only but the dot is also fine in yterms of size/brightness - tested by trial) Wondering how it will hold in the long run but this is not real concern atm. I am very satisfied !
  3. OK so I wanted to change the ejection pattern and adjusted the angle of the ejector. Now no ejection issues, ejection pattern is lower and more to the back (around 4pm) and brass rarely hits the red dot. There are tow cases when it happens: if the splits are sub 15-17 ms and slide starts to come back too early and brass bounces from the back of slide and then from the back / edge of red dot or as I am using the different pickup brass when the brass is somehow used / in bad shape. Overall I am vey satisfied with this setup. We will see how it will behave in longer run Link to video with current ejection pattern https://i.imgur.com/7cYKz0N.mp4
  4. So after 200 rounds I can say I am very satisfied. The brass slightly dings the very corner of the red dot but that does not cause any ejection issues so far. Monday will have more oppty to shoot on level 1 IPSC match so will have more info to add. Here is link to video how it shoots: https://imgur.com/2urrW6J
  5. After a little bit of filing managed to mount 510c on my gun today. Tomorrow will be first test. My only potential concern are extraction issues. I'm a little bit surprosed by the size of the window
  6. The residue from last photo is not from Lovex - it is from Vectan SP2(as described). Brown flakes from earlier photo though are remainings of 37.1
  7. I am using regular Fiochi SP primers. They are priced well, available, have no issues using them etc and they seem to be doing good job in all my 9mm Major loads. The gossip says the Explosia was making the AA7 for American market. Not sure is it true or not but as I am located in Europe Lovex with various powders is IMHO one of the most commonly used powder in Poland, Czech and Slovakia (availability, proce point, various powders range etc). The feature of Lovex 37.1 (apart how it shoots, measures, etc) I like a lot is easy cleaning compared to vectan SP2. Lovex leaves unbrnet brown particles all over inside of the gun but it does not leaves the solid residue. One thing I am not sure yet is its temperature sensitivity and how it influences PF and pressure . Sometimes in winter I shoot under 0 celcisus / freezing point and in Summer it might be +35 Celcius. Below is example what Vectan SP leaves inside and outside gun:
  8. I used Lovex and two other powders for IPC 9mm Major load with CMJ 123 gn LOS bullets (165-167 PF): 1. 3N38 - meters relatively well, shots soft but it requires compressed loads and it is hardly available and pricey in my location plus it fills case almost full so I got a lot of spills (OAL 30.00 mm ; 8,05 gn of 3N38) 2. Vectan SP2 - meters terribly, leaks plus is static electricity sensible and then measurements are +- 0,1 gn, leaves dark hard residue in the gun which requires cleaning more often, leaves rougly 3-4mm from the case rim - so almost no compression, shots nice but it seems there is too little gas but it shoots flat, mid prices issues with availabilioty from time to time (OAL 30.00. 8,7 gn) 3. Lovex 37.1 - meters very good and consitently, if required compresses relatively well, shoots flat and shot impulse is softer than in SP2 but harder than 3N38, leaves no permanent/hard to clean residue in the gun (looks like brown flakes but no dark dirty residue), is relatively dense but you need more of it to get PF, leaves similar amount of space for bullet similary to Vectan SP2 and is available and cheap (in my location). The only downsides with Lovex in general is that they used to have some batches of powder that were not exactly to spceification, but havent seen such case since year or two (OAL 30.00 mm, 9,9 gn Lovex 37.1). Summarising : highly recommending it. Works great and has excellent price/performance for me. This is how the back of the gun looks like after shooting 400 rounds on lovex (looks dirty but is very easy to clean. This is not copper from the brass but lovex remainings):
  9. IMHO simplest way is to glue with superglue two small tabs of polyurethane or other hard rubber/plastic to grip safety. it is easy to remove just in case amd you need no special tools. Cutting the small tabs to required size plus glue assures they will not migrate into the grip.

    Bul Armory?

    I assume this is normal ? Or is there something I should do with it ? Gun shoots fine. I am very happy with it.

    Mine looked a little bit different. I polished small burs (visible on the picture) and it seems to be working fine

    As for the photo - it seems that you are right. So here is the top of the slide stop. Not sure but it seems that on the photo below there is a sign of the link and two spots where it touches the lower lugs.

    Bul Armory?

    Please find image of a slide stop with the signs from lower lugs. if there are marks then the lower lugs contact the slide stop. This is at least how it looks in mine (Bul SAS Ii UR Open)

    It works also very well with 9mm Major loads. Built with quality, tight tolerances and works out of the box with minor and major loads. Magazines are Para type magazines but you can use original Bul or SPS magazines as well.
  15. I tested the drag of slide stop over lower lugs (with some blue dye) and quite honestly saw none or only minimal signs, so I just cleaned the burs' edges and and polished it lightly. I will observe how it behaves and hope it is just sign of break in process for this 2011. New platform for me so collecting new experiences. It is just different but like it a lot so far .
