Is it possible to convert a G21 to 9x25 dillon? If so how can I do it?
Lone Wolf is about the only place to get 9x25 barrels these days and they only offer them for the G20. They have barrels to convert the G21 to either .40 super, or 400 Corbon, but that's it.
Check out the .40 super at double Tap here:
And bear in mind that DT's velocity claims are usually about 100 FPS or more faster than your own chrono will show, but even so, the .40 Super is no slow poke. If I already had a G21 I think I'd go for it, but I already have a G20 and this conversion isn't available for the G20.
.40 super will perfectly fit the breech face and extractor of a G21, whereas 9x25 Dillon will not, so it might be a better idea for the G21 anyway. Plus you won't need new mags, which you would even if you could convert to 9x25, which you apparently can't. Just drop the .40 Super barrel into your G21 and you'd be good to go.
Here's more about the cartridge on Wiki.
Almost forgot to mention that a G21 to .40 super conversion would probably work better with a stronger recoil spring than the stock one. A 20, or better yet, a 22 pound spring would be a good idea. But that and the barrel would be the extent of what you need for the conversion.
But lone wolf does offer a G20LS, which it states on it's website will fit a Glock 21, along with the 6 inch barrel for 9x25 which would work with the lone wolf G20LS, so theoretically you can make your G21 frame shoot 9x25 dillon or 10mm.
My only question, is there any difference between a G20 and G21 frame that would change the reliability of putting a LW G20LS w/ 9x25 barrel on a G21 frame vs. a G20 frame?
Yes, I brought the thread back from the dead, but now I have a question on this topic.
