Should it fit a P226R holster?

At the minimum, Vedder does. https://www.vedderholsters.com/sig-sauer-p226-mk25-navy/

E: just realized the p226r is the curved Sig rail and not the squared one on the mk25.
Finally getting around to this, and it's such a drag that they make their full range for the P226R but not the Mk25... and the full range is available for the HK45C which I swear is bigger than either but has that essential "C" in the name. I picked the one IWB-cursed 9mm in SIG's whole line-up

SVMS-01 UNION FLAG GREATEST MOBILE SUIT

ENACT = CHEAP EUROTRASH COPY






What's necessary to build a P320 in .40 S&W? Is it just a change of barrel + recoil spring or does it require a different slide/frame? I'm considering getting one with my last permit but I also wanted to get something in .40 because it's always in stock at my LGS for cheaper than 9mm and I have a bunch of it for my PC carbine already. Has anyone here done this?

Slide, barrel, and spring. Only thing that transfers seamlessly is the FCU. And the grip, of course.

I might be rewarding myself for getting through the past couple of years with a more expensive fun gun, and am looking at options. Iím thinking about uncommon guns that can be SBRed relatively easily, and have been eyeing an SG553P. For reference, a couple other thoughts Iíve had are things like the MPX, SL8 converted to G36 specs, USC converted to UMP specs, any maybe some others. I really just want a well-made, fun, relatively ambidextrous friendly SBR that would stand out more than an AR15.

Question for the thread: Iíve seen some .300 Blackout 553Ps for sale, but they have a long barrel. What are the chances that these can be cut down to 8.9Ē without any fuss?

Honestly, I think Iíd prefer one in 5.56, but for something like this I could go either way and Iíve seen more in .300 lately.

"Hmm, these sights just aren't high enough. I should get suppressor-height night sights."

"Oh look, for an extra $500 on top of that hypothetical cost I can get an entire slide with a dot and non-night sights! What a deal!"





Haven't shot it yet, but the dot is exactly where I expected it with a quick aim and the shake-awake works perfectly. That'll do.

OK, an update for the crickets: I decided to go with a P556 rather than a 553. It is about 90% of the gun I want, and much cheaper. Iím starting to pull pieces together to make it what I want it to be (aluminum Swiss style lower (with folding stock pending stamp), MFI diopter sights, etc.).

Mine has fishgill style handguards, which is OK but not quite the look Iím going for long-term. Does anyone have a line on a set of the classic plastic non-fishgill handguards?

Iíll keep trolling Gunbroker and AR15 EE in the meantime.

You can find them, but they tend to be expensive. Here's one I found selling 551 handguards for a bit over $200.

I've never seen the SIG non-fishgill handguards for sale. They only ever came on the 551a1 and I think the 556 classic (maybe?), and either way they're even harder to find than the swiss ones. You really only saw them for sale when someone sold them because they got the swiss ones. Hell, I've only actually known one person other than myself to sell them.

I think he's talking about the short P556 handguards, seen here. Those seem to be especially rare to find for sale because there weren't any nicer Swiss part for owners to upgrade to like they could with the full-size 556/551-A1. (The P556 was a 10" barrel instead of an 8.9" like the 552/553, so the piston and handguards are a different length to the Swiss counterparts and don't interchange.) Judging from that WTB thread that I linked, you're going to have a hard time finding any examples for sale unless you're willing to wait a while.

The other option that used to be popular way back was buying a set of 550 handguards and sending them to Double Diamond Law Enforcement Supply to have them cut down to fit the P556. This was about as accurate as you could get because actual SIG 552/553 handguard are cut-down from 550 handguards (they don't have the rear swell that 551 handguards have), so you'd get the same look as the real deal Swiss guns. That said, I have no idea if they still offer this service. They still offer SIG 55x stuff on their website, so...maybe? If you reach out to them and they do still offer the service, you can get 550 handguards cheap here and here, but be aware that you will be waiting for them.

Nail on the head. Parts for these are sometimes difficult (at best) to get, the short handguards are drat near impossible to find.

The current set of fishgills I have I actually stumbled on while looking for my P556. The P556 I ended up with had a quad rail handguard on it with an integrated top rail, but I couldnít use it since I wanted to go with MFI sights. A guy that was selling a different gun mentioned that he still had his stock handguards that would be included in his sale, so I asked if I could take those off his hands for a fair price.

When I got them, I got a kick out of the fact that the short fishgills are just cut down full size ones with an end cap, ala SIG 552/3 handguards being cut down 550 handguards (though not nearly as nice of a design). I guess the short gas systems were kind of an afterthought all around.

Question: I finally got around to mounting my Romeo 1 Pro on my X-VTAC R2 (only mentioning this because it also tells what sights I'm using) tonight and the sight picture isn't ideal. I think it's due to my installing the steel shroud, as I'm only JUST able to pick up the front sight when *burying* the dot between the RMR's rear sight.

For others who are using/have used the R1P, did you install the protective shroud? And yes, I did install it using a torque wrench to the recommended 30lbs.

EDIT: Yes, the weapon was clear and unloaded when I took these, and no, I haven't zeroed it yet:

This one showcases how difficult it is to pick up the front sight:



And this one is what I mean when I say "I have to bury the dot":



I also want to emphasize that this is the first red dot sight I've bought for one of my own guns, so any advice would be appreciated.

You need to zero the red dot before you judge. I have a R1P with a steel shroud installed on a P320 Pro (4.7" barrel with iron sights on the slide) and mine doesn't cowitness at all. I can't even see the irons with the dot in-between. I plan on getting suppressor height sights once I swap over to an RMR. Pics in a sec..



You can see that the rear iron sights don't even clear the R1P body and even trying to use the R1P rear notch the POA would be no where near where the dot is zeroed.

You can see some sight pics with shroud removed and installed here:

Thanks. I've never zeroed a red dot before, only prism and LPVO optics on my AR, and learning whatever I can now will help immensely when the 9mm Banshee 300 I just ordered tonight arrives sometime in February/March of next year, since I'm planning on putting a Holosun (or an Eotech, if I can get a good deal between now and then) on it.

I've watched a few videos in the past few hours and it sounds like I'm going to have to learn to 1) focus on the target, not the dot, and 2) as you said, the dot doesn't have to cowitness with the front sight at all.

Question!

New gun owner, picked up a P226 and hit the range twice. First time ran about 80 rounds through with no issues. Second time was a few days ago, towards the end of the first mag my shots started going comically to the side more and more and the sight felt weird.

Well I somehow couldn't fathom that the sight might be moving and another shot sent the front sight into orbit.



Anybody have an idea of what I could do? The rear sight is stamped at a #8 but I have no idea what the front sight stamp was. Seems it could be either #6 or #8. Not sure if there's a good place to try to get a set of sights, not sure if it makes sense to get a tritium replacement or try to get an original set, etc. etc.

Quality being very important. I wouldn't trust any of the Sig pistol optics unless they've improved dramatically. Even an RMR I have is not on a pistol since it flickered off from recoil enough under shooting that I couldn't trust it on one - it's a type one however and the newer type twos don't seem to have that issue. I've had good luck with Holosuns 507 and 508, and the Leupold Delta Point Pro (sold this one but it was fine on an M17 I had, not sure if I'd want to take a spill with it however), I'm sure the Holosun 509 and Aimpoint P series are fine but I haven't shot them.

The rear sights on my M17 are loose and lifting off the slide, has anyone seen or dealt with anything similar before?

First pistol I've owned, got it new about 6 months ago and have only fired 300-400 rounds so far. So I'm a bit surprised to see issues so soon.

Take the slide off the frame, remove the extractor plunger as you would to install a new extractor, and there should be two holes with screws holding it in place. Take out the screws, apply some loctite or similar, and screw them back in after reseating the sight plate. There is a loaded chamber indicator spring that's easy to lose under the sight plate - so make sure to be cautious when doing this so you do not lose it. Sounds like someone at the factory just was lazy on the screw install.

That's my thinking too. I'm comfortable with the Sig Romeo1Pro on my XCompact.

edit; like, if you've practiced a bit with your RDS, you should be able to present your pistol and see the dot. Every time. If the dot isn't there, you should still be pointed right to hit a torso sized target at ~5 yards. Right?

Can you dry fire it with a coin sitting on the slide / sight and not falling off or sliding? People at the range thought I was some kind of natural when I started and used the loaner P226 with the line on the back, but not long after I bought my own Mk25 I had a bad string of pushing left. Don't take this wrong but it's a sturdy gun and probably not your sights unless there's a jiggle. You can also check this by using a ruler / string / laser level to check the alignment from front to back.

I pushed left because the Mk25 grips are the screw panels instead of the E2 that everything else gets now, so getting the E2 and working on my support hand really helped. What direction and how far are you drifting?

Also having the tritium on the Mk25 I can only say they're of questionable usefulness if you don't plan to use your gun at night (I'm Canadian so that's very unlikely). If you end up replacing them find the best contrast set that your eyes pick up or look into glow-in-the-dark, which on my HK45C are much easier on my eyes.

Iíve never noticed that movement causing problems at the range. Itís not exactly a precision sight to begin with. I suspect you could shim it internally.

What does help a lot, though is throwing some green loctite on the elevation adjustment screw. Get it dialed in for one aperture and then lock it in. Otherwise that screw moves under recoil and then youíve got elevation going everywhere.
