I have been a long time 1911 and Glock fan where in my world the .45 ACP reigned supreme.
I recently started expanding my 1911 collection to include Dan Wesson offerings in both 10mm and 38 Super, and thought if it was good enough for my 1911s it should be great in a Glock as well.
The first thing I did was to buy a Storm Lake 10mm conversion barrel for my G30SF.
Then I bought a gen4 G20 complete upper for my G41 then ultimately purchased a Glock 40mos.
With my Glock 10mm itch scratched I began looking for what was available in 38 Super.
I quickly learned of only 1 choice. My search lead to a Lone Wolf 6" G40 conversion barrel in 38 Super.
I ordered it and I just installed into my G40 slide. I know, crazy right. It fit perfectly.
Then I loaded up a G40 10mm mag with 17 rounds and cycled them through this set up with only one issue.
The slide locked open with one round left in the mag.
So it will be off to the range to test this converted Beast to see how it runs.
Anyone ever done this before? If so, how did it run?
What problems should I expect?
Any other thoughts would be greatly appreciated!

38 Super in a 10mm mag

Ejection was perfect when hand cycled

Jeez....a 38 super glock. That has me yearning a bit.
+P's should run well in the G20, but the G40 slide may require a lighter RSA. The .38S is stout, but the G40 slide mass may be too much. You can also try it in your G41 slide, which is a little lighter. Standard pressure .38S may require a lighter RSA in the G20, and I don't know how they will work with the long slides. Polishing the locking lug cam surfaces can also help speed it up a little. Don't polish the locking block, or it may affect the other calibers.
To help the last-round-magazine issue, either take a little material off the slide-catch step, just enough to engage the catch to the top of the slide notch (too much and the 10's won't catch), or use a .45ACP follower. both may need a bit of fine tuning in the Gen3 mag, but maybe not as much in the Gen4 mag (I haven't tried the Gen4 mags with this).
Another "caliber bonus" is, you can also shoot 9mm in the .38S barrel. The same cautions should be observed as with the .40SW in a 10mm barrel.

Yes I did it.
You will have some feeding problems. You will most likely need to bend the feed lips of the G20 magazine.
.
Thanks for the feedback about feeding issues. Good to know.
This kinda moves the post forward a bit on a set of tests I want to do, as it gives me a 38 super barrel for the Glock. Now I just gotta save my pennies for a 38 super barrel for my new G20SF, and find a shooting buddy with a G21.
I picked up a 6" 9mm LWD barrel and spring set for my G-20 and it works pretty good.
Although I like the 357Sig and 9x25 Dillon cartridge performance from my 10mm guns... ;D
I love the versatility of Glocks. 38 Super in a 10mm, who else can do that?
I want a 38 Super barrel for my G29 now. Yeah I know there's the 9x25 dillon but that has too much muzzle blast. The 38 Super should also allow for an extra round or two in the magazine.

1911, but only if you are pretty handy with a file, or get stupid lucky on a "drop-in" 1911 barrel.
A dedicated magazine sounds as if it is the solution to the problem. If you like a 9mm bullet, it seems to be the way to go.
Interesting. I didn't know such a beast existed.
I read a lot about the .38 Super and it's "accuracy problems" (from the original Colt products). When chambering on the case mouth, the "accuracy problems" miraculously disappeared! (Strange how that works). :)
In a 6" slide and barrel, the 124 grain bullet seems the best way to duplicate/exceed the "police proven" .357 S&W Magnum 125 grain JHP loads. With more ammunition it is what Colt was trying to accomplish 87 years ago in 1929. Penetration coupled with substantial expansion will likely result in enhanced tissue disruption (both temporary and permanent).
