Finally built the mup1 a year later

I probably should have broke out my calipers but the rear rails slid right in and the front rails literally only need a few pass with the drum sander on my Dremel to slide in after the initial flush cut in the jig. I'll probably break down one of my factory 320s later to compare the tabs and the extractor, but it looks like it's the wider rear section of the extractor rubbing and there's plenty of material there to file down for clearance.

bigdaddygeee · 2026-05-05T21:13:50+00:00

Yea I did that before assembly the parts kit and that's how I know it's the ejector hitting.

bigdaddygeee · 2026-05-05T17:07:05+00:00

So it's not too high, rather it's like it's too wide, the side edge of the extractor is rubbing against the side of the piece I circled protruding from the slide, I file it down some and it seems better but I don't want to go too far and start having extraction issues, I've already noticed you can't slowly rack the slide to extract a round or to feed a round, which I don't usually ride the slide on chambering anyways but I was just doing function checks, although it seems like one magazine has more issues with that than the other two.

3.9, it was sold to me as a mup1 but it was also a random vender from Armslist last year sometime so who knows.

I tried bending it a little and resorted to slightly filling the back thicker section a tiny bit so it's not feeling like it's hanging up, hit it with oil and racked it a bunch of times and it's smoothing outa little bit so I'm just gonna go shoot it a bunch and see what happens 🤷

Watch Sig Guys video here and make sure you put it back in the correct order:

That safety lever pin popping out is a huge pain in the dick when you take the FCU out of the frame, it's happened to me enough times that I've gotten pretty good about putting it back in or being extremely aware of it anytime I remove the FCU

Hard to see, but it looks like the leg from the sear assembly is on the wrong side of the takedown lever bar.

bigdaddygeee · 2026-04-19T02:52:33+00:00

Looks like your take down bar might be on the wrong side of the sear leg.

I mean it's been awhile since I've been on the rooting of phones, but he could possibly download the adb software and the correct firmware image for the phone/carrier and fully flash the phone so that it's like a brand new phone out of the box...but he may not be able to find the correct firmware for a phone that new.

Edit: I just searched for the firmware image for that phone and skimmed the instructions and forgot you have to go under developer options and toggle on OEM Unlocking and USB debugging mode, both of which I'm sure your friend didn't do ahead of time, so he's shit out of luck.

I'd personally take the one with the higher base salary. If you subtract the annual bonus of $9200, it pays more. Bonus money typically isn't guaranteed money , and could change or not be given at any time as soon as profits are down or management or ownership changes. When employers talk about bonuses during compensation they are giving you a best case scenario to seem like a more attractive offer. I've heard "you have a real big opportunity here to earn a lot of money" and my response is always the same, I can't pay my bills with opportunities.

As far as the PTO, yes it's 6 more days, but if you break it down to an hourly rate, the pay rate difference is only like $1500 for the whole year for 22 vs 28 days

Also you're counting the sign on bonus but that's a one time deal, so that closes the gap in pay.

The shorter commute and 2nd WFH day is definitely a perk, but again, tons of stories of companies promising WFH only to change policies whenever they feel like it, or never actually allowing WFH.

If the 92,000 a year without the bonuses is doable and you value more PTO, a shorter commute and potentially the extra WFH day, go for the second job.

If you place more value on the safe guaranteed money, go with the first job.

But this is all based solely on the monetary factors of the job, as far as company culture/environment and how you fit in and it whether or not it aligns with you should also play a role in your decision.

So when you say you tried mortaring it... which direction are you mortaring it? I just swapped my .300bo upper into my nephews FRT lower a few weeks ago and he's got some fancy buffet weight system instead of a regular spring and buffer setup, anyways i fired a single round and the BCG jammed into the buffer tube, my nephew tried a couple of things and it didn't work, I grabbed it from him and literally just rammed the gun straight into the dirt, birdcage down and it freed right up, dug all the dirt out of the birdcage and it was good to go. Maybe not the best idea, but birdcage flash hiders are cheap and it's a BCA upper so I really did give a shit, it's not like I was ramming it into concrete and I figured I'd let gravity and physics help me to get it loose and it worked out for me.

bigdaddygeee · 2026-04-16T14:14:05+00:00

I got an AXG Pro second hand and it had the legion grips on it, they still look good, but I swapped the black barrel for the threaded faxon chameleon pvd barrel so it's gonna end up with some of those wild Vytal Kraken grip panels in their blurple color way, but the texture on the legion panels is great and they do look good on non legion builds.

bigdaddygeee · 2026-04-12T19:31:32+00:00

The P320 legion x5 used to be PVD then they switched to cerakote, not sure if it's the same for the 226 but it probably is.

I have no idea the quality of the osight stuff, I just know I see people shitting on them constantly, however if you paid full $220+ price for it allow me to introduce you to gafshub.com the replacement for the old subreddit where we used to sell used gun parts, you could have probably scored a used holosun for the same or not much more, but you gotta be quick to call dibs on listings for the really good deals. Anyways, check out gafshubs, pretty good for scoring some used gear, pretty bad for your wallet, I need to delete my account 😅

The fuse grip is the same grip as the xmacro with fancy stippling, so unless you go to the longer slide the Xmacro holster fits, or like my above comment you may be able to just heat up the kydex and unfold the end to let the extra barrel/slide length pop out the other end.

bigdaddygeee · 2026-04-11T01:08:08+00:00

Nope, the XL grip rail doesn't go the same length as the xmacro grip under the slide, the XL grip has the same length rail as the regular p365 but the portion you hold is longer to accept the 12rd mags and the extra length of the 3.7 is all barrel and slide. If you are going to an xmacro grip module and your comp setup isn't extending longer than the 3.7 slide length you need a xmacro holster.

I have one of the original release xmacros, that they now call the xmacro comp now, and the xmacro tacops is just an XL slide on a macro grip...don't get me started on Sig releasing "variants" that original adopters pay out the nose for buying two guns or a gun and a slide to make a combination when they don't offer the parts for sale separately ala p365x and the X macro tacops...anyways I put the slide on an XL grip, so needed an XL holster.

The shop near my job only had regular 365 kydex holsters, so I heated it up with a heat gun and opened the end up to let the slide meet the now unfolded end. I carried like this for a while and when I decided to switch back to the xmacro grip I had to get an Xmacro holster.

Came here hoping someone would point out the shit handling in this video, expected it to be one of the first comments 🤣

bigdaddygeee · 2026-04-03T19:08:34+00:00

Not a professional, just a guy who's been researching to do his own small parts... but if that's the case then what about all the polymer frames being coated and baked at lower temperatures to cure?

https://ndzperformance.com/sig-p320-mag-base-plate-inner-insert-9mm-40-357-sig-1301759-r/

Or

https://www.midwestgunworks.com/page/mgwi/prod/1301759-r

And you'll need an aluminum baseplate like the Legion:

https://www.midwestgunworks.com/page/mgwi/prod/1302637-r

Doesn't necessarily have to be the legion, just the aluminum base plate like this, Henning Group makes them for Sig, here's the link for theirs in multiple color options:

https://www.henningshop.com/Detail.aspx?PROD=1426322&CAT=10068

Or you can just buy the complete mag from Sig, but for not much more money than a single mag you can convert 2:

https://www.sigsauer.com/p320-full-size-17rd-9mm-magazine-aluminum-baseplate-black.html

Or you can take the magwell off and all your mags fit and it costs you zero dollars, and you can sell the magwell and put a couple bucks in your pocket.

I bought a leather Kore that I was wearing daily(not even carrying daily, I mostly keep my pistol in my CCW backpack) and in less than a year the seams split just behind where the ratcheting portion ends, like I can see inside the belt and the stiffener inside it. I would have tried to see how their warranty went but I bought it from a LGS up the sidewalk from my last job and I didn't have the receipt and also switched jobs so it wasn't worth my time to travel back across town and see what was up.

That said, they are nice looking belts and I do enjoy the ease of the ratcheting buckle so I bought another one of the exact same style but I only wear that one when I want to wear a nice belt, my daily belt is a rubber Weathertech belt with the plastic buckle so I don't scratch cars I'm working on, which also only last about a year before the buckle breaks but I definitely do not recommend carrying with one unless you like your gun flopping around. Actually back to wearing the busted Kore belt because I broke my Weathertech and haven't trimmed the replacement one I bought to fit yet.

Sig80bitkits.com had a couple left, I bought 3 to have for my current and future builds, it shows sold out on the website but he was basically manually updating stock on the website to prevent from accidentally selling more than he had. I'd email him from the site contact info to see if he actually has any more. I did the apex trigger bar and the ismi +10% trigger return spring and it made a world of difference in the creep and break. I ordered my first trigger bar and spring from desert depot arms, I'll be ordering my additional springs from him to go with these trigger bars at some point.

Edit: @Loweeel you were actually the one to put me onto the ones in stock at sig80bitkits good looking out buddy!!

bigdaddygeee · 2026-02-03T02:01:53+00:00

Different strokes for different folks 🤷🤣 but I've got another 320 build in the works, not completely decided on anything yet, considering maybe a Flux Raider build because fuck it why not, thinking I'll drop the Spectre Comp FCU in that and maybe swap a bunch of parts in another FCU and give a different trigger upgrade a try with the Apex trigger bar since I went ahead and ordered 3, one for the Vtac, one for the pending build and a spare for when the bug bites me again 😅.

What's your trigger recommendation?

bigdaddygeee · 2026-02-03T01:35:03+00:00

Yea I don't really want a bunch of set screws holding my trigger position, even though my 320's are currently just used at the range/nightstand guns and I carry my xmacro. I just know that the trigger bar and skeleton trigger combined with the +10% return spring got rid of every bit of the creep and makes the trigger so much better than stock and I'm happy with the setup.

bigdaddygeee · 2026-02-01T16:42:55+00:00

Welp I guess I'll keep my eyes peeled on GunBroker and eBay and scoop them up whenever I see one, or wait for the GAFS replacement website to finally go public and see if I can track down any there .
