Clock 21 to 10 mm conversion
« on: May 10, 2013, 11:37:24 AM »
So I finally gave up on the 40 cal conversion.
 
I am going to try the 10mm conversion. I found the bbl I need and am about ready to pull the trigger on that. Question is; I'm thinking I need 10 mm magazines. If that isn't true let me know. If it is, will the 10 mm mags work in my 21 frame. Anyone have info or experience on that?

The 20 and 21 share the same frame. The 10mm mags will work just fine. I'd probably pick up a 10mm extractor as well, just in case.
The .45 extractor will likely work fine, but============.\

Wouldn't you instead need a 40 cal. slide instead of a 45acp slide?

Dee, the reason I gave up on the 40 cal conversion was the fact that A Glock guy at the NRA convention told me the frames were different and the 40 cal slide would not fit on a 21 frame. But The Storm lake folks say you just need a barrel. But I am open to enlightenment.

Well my question would be: How are you going to get the 45acp bolt face with a a case head diameter of .480 to align, center and hold, a 10mm cartridge with a case head diameter of .425? I would not think this possible. It might fire the round but, due to the machining differences according to this the left side of the 45acp bolt face would not hold the 10mm against the extractor.

Thats a fair question, Dee! I will have to get an answer before I spend the $175 on a barrel, and the $30 + for the magazines, and whatever a 10 mm  extracter costs.
This is not a "must have" but a project. I could of course buy a new pistol, but what fun is that?

I've been wrong before but, I don't see a Glock 45acp slide handling a10mm round regardless of any parts changing.

I'm going to check with the barrel maker to see what they say. I will have to be convinced before I throw away money on a barrel and  magazines, when I could add some and get a whole new pistol. Ive been seeing lots of 10 mm ammo and thought it would make a good hog round from a ground blind I have in the woods.
 
 Hogs come within 30 yds and pistol shooting has always been a love of mine for hunting. Unfortunately I sold my 44 mag a few years ago to buy my youngest son his first  shotgun.

I personally like the 10mm round myself, and would like to have one in a Glock, but as I said, the Glock 21 slides bold face is milled for the 45acp case head, and I just don't see it working at all. Let me know how that works out.

Well, as it turns out, LW makes conversion barrels for the mdl 21 in .40 Super, and 9x25 Dillon only. Both of which are based on the .45 acp case. Not sure why that is, as the 9mm conversion works just fine with the .40 breech face. But there ya go, if you want a hot 10mm out of the mdl 21, go with the .40 super. Your .45 mags will work as well.
Hope that will scratch your itch! Have fun.

Between the two, (10mm/.40 Super) I'd go with the 10mm. Brass is available, and the straight wall case is much easier to load for.
Conversion barrel from Storm Lake $160 + magazines = large frame Glock in 10mm for cheap!

??? I could have sworn I posted in this thread a couple days back????

Just to clarify.  Brother Savage, the 9x25 Dillon is not based of a 45 case. It's based off a 10mm case.


I have a G20 in 10 and love the caliber. Teamed with a better 6" barrel some damn respectable numbers can be achieved!  My loadings with 200XTP exceed 1250fps.


I thought hard on the 45 super in a 21. But ultimately went with the 20 as I have a bunch of 1911 guns and don't need to make a mistake loading a hot loaded 30+ cup round I to a gun designed for under 20k.

I have shot a bucket of 9mm thru my g23 with a LW conversion barrel with not a single hiccup! I have read of guys shooting 10's outa 21's but IIRC reliability was spoty.

If this needed to be reliable, I would buy the slide and barrel.

Frankly, CW I was surprised I hadn't seen your post here already!  ;)  I am so glad you did!

Is good enough for me. Having a pistol that had possibly spotty performamce. is not acceptable, as far as I am concerned. Coupled with Dees concerns and some reviews I read on line, I think I may not try to reinvent the wheel and just get  a 20 with a long barrel. Now, a 20 with a long slide and long barrel would be the ticket, I always want my cake and eat it too. This quest continues!  I appreciate you fellas input and continue to respect your knowledge.

You are indeed correct as to the parent case of the 9x25 Dillon. Don't know what I was thinking. Thanks for the correction.
No real experience with the 21 conversion to 10mm, but don't know why it wouldn't work as well as the 40-9 conversions have for myself and others. My current production/ESP gun is a mdl 35 with a LW conversion barrel.  It runs like a ------------well, like a Glock. I don't tolerate spotty performance.
Still, nothing like having a dedicated 10mm, and the mdl 20 is the one to have.
