XDS-40 to 10mm

[StockIIBoss]

I'm still excited about the conversion. Really just waiting for a XDS-40 to show up at a LGS. I'll have my caliper at the ready! It always pleases counter sales when you aren't there to buy. LOL

From the Springfield site pics I've overlayed, it looks like the ejection port is slightly smaller on the 40's slide, so barrel lockup dimensions will also be different. As mentioned, ejecting a live round would be via the grip if that's the case. But is it worth the 'cool' factor to have a 10mm as thin as the XDS. Yes? I mean YES!

I have an XDS-40 on the way. I'll have the answers next week.

If you want more power for the woods, a friend of mine (  flyandscuba ) shoots 45 super thru his XDS 45  for a few years now.no change to anything. After watching him I started doin the same thing. Ive seen no signs of battering yet.altho i dont shoot a lot of them i dont shy away from it either.
   If you just want 10 mm and like projects just cause, i competly understand. But 45 super is equal to or a little stronger than 10 mm so that tells me when you get it together you should have no problems with durability  . Search flyandscuba and you can get his info and chrony results

I shot 45 Super out of my Glcok 21 with 24# spring and LW barrel, and after 50 rounds my Glock was beat to crap. I will never shoot 45 Super out of a gun that was not specifically designed to shoot that caliber. I can't see where the little XDS would be able to handle that cartridge that much better.

Lots of people shoot 45 super outta there glocks no problem.hell there has been 460 rowlands on that same platform for years.donno what to tell you. Except maybe its not for you.

I hadn't though about 45 Super, or even knew about it. I'm familiar with the 38 Super, but that was it. I'm starting to like the sound of that. In the mean time, the XDS 40 arrived today, so I got right on it.

The good news is that it can easily be converted to 10mm. The 40 slide works perfectly on the 45 frame. They are identical except for the two spacer ribs in the magazine well. So, you can just use a 45 frame with no mods, or grind the ribs on the 40 S&W frame and use the 45ACP magazines. If you wanted to leave your XDS 45 in tact, just sand away. It's such that it would be a very easy job to sand or file down without hacking up the interior. In that case, you wouldn't have any need for the XDS 45. Just buy the 40, file down the ribs, and use the 45 magazines. Other "good" news is that the 40's barrel is stout. It actually fits into the 45 slide and pretty much fills the hole. And there appears to be plenty of surrounding chamber material that reaming to 10mm headspace won't impinge the barrel wall.

Now for the bad news. The ejection port is too small to manually clear a live round. You folks already suspected that could be an issue, and you were right. So, if it becomes necessary to clear a failed round, you must drop the magazine first and clear the round through the magazine well. Bummer. Not a deal breaker for the conversion for me, though. And I'm going to proceed by sending the barrel off to Ohio to have it reamed.

Now, let's argue, er discuss, about whether you should or could use the conversion for a carry weapon. I converted a CS40 Chief's Special to 10mm, which was the perfect platform for it, and easy to do, and it shot like a dream. However, I tried carrying it and it was just too heavy and chunky, and so it sat in the safe until I eventually sold it. The XDS on the other hand, is very thin and not that heavy, and I've carried the XDS45 concealed plenty of times. Depending on how reliable it feeds and how it shoots, I wouldn't have any problems carrying it for self defense. I've not once had any 10mm ammunition fail on me, so I trust that, but if it's fussy about feeding properly, then that's an entire eyebrows raising concern.

So yea, nay, I'm a crazy mofo, have fun, let a stranger at the range shoot it first?

Rowland uses a comp. I can't have a threaded barrel on my pistol in California, and I do not feel like dedicating a slide and barrel to 460 Rowland or 45 Super by welding a comp on the barrel.

  Here's an interesting tidbit the Glock 30 recoil spring assembly fits and functions in the XDS it does hang out a little bit on the front but it fires and cycles fine this allows you to change the recoil spring rate because Glock's have many options in that department. Also the aftermarket recoil guide assembly like from wolf or something like that can easily be modified to be just short enough to fit in the XDS but for experimenting you can just stuff a  Glock 30 recoil assembly in there and it will be fine  .

So does the Glock 19 (in my XDS 4.0")

Yes, a compensator is required for .460R, however, you can have a threaded barrel in CA. Threaded barrels are not illegal. An assembled pistol with a threaded barrel, on the other hand, is illegal. An assembled slide and barrel with a compensator properly installed (requires "gunsmithing skills" and specific tools), is NOT considered a threaded barrel. The "threaded barrel" definition in CA is any barrel design, capable of readily accepting installation of a prohibited device, and is not limited to only threads. For this reason, the law also requires an "intent to assemble" such prohibited devices. The process of removing and/or installing the compensator is a "state of repair" condition, meaning the threaded barrel is not recognized as such during that period. Ideally, it's much easier to just dedicate a slide to a barrel with a comp, but you certainly do not have to "weld" it on. A set screw and Loc-Tite is sufficient to satisfy the "permanently attached" requirement. You can go a step further, if you wish, and fill the set screw with a compound (RTV, epoxy, etc.), which requires greater professional skills to remove. Even welded comps are "removable", by the same definition (often easier, too). If you are in possession of a threaded barrel with an attached comp, and are not in possession of a prohibited device that will fit it (flash hider, can), then there is no "intent to assemble" (legal term) a prohibited firearm.

Simply stated, CA laws are a PITA. However, there are ways to have what you want (with obvious limitations), and still remain legal. Also, barrel threading is not the only method of attaching a comp (or whatever, including prohibited devices).

My .460R build is a G21 with dedicated long slide, barrel and comp. While I could swap barrels as needed, I simply don't. The .460R setup fires and cycles .45ACP and .45 Super just fine as it is. An added bonus is, they recoil like a .22LR.

As far as .45 Super goes, any Glock .45ACP will handle it just fine. A heavier RSA is recommended, but certainly not required. If you don't want/need more power than that, then you already have what's required to reach your goal (if you have a Glock .45ACP). Just the same, any Glock .45ACP can be easily converted to reliably fire 10mm Auto with nothing more than a barrel swap (Glock OEM or aftermarket), although earlier models should be updated with an LCI extractor for more frequent 10mm use.

In regards to the XDS .40 to 10mm conversion, any use other than range/target shooting is unacceptable if an unfired round cannot be cycled/cleared. Although some accommodations can be made, such as enlarging the ejection port about 1/8", or limiting COAL to 1.150" or less (which would only present an issue with "factory" length 10mm ammo), the inability to clear a jam or squib in a combat situation, even for home defense, is simply unacceptable. There are already more than enough disadvantages stacked against you, and to add a known failure to the equation is irresponsible.

Machine shop called. Nitride barrel could not be cut with their reamer. Too hard. Bummer. Somebody please let me know if you have a source for this. Tnx.

A good machinist should be able to single point the chamber with a carbide bit.
