Quoted: To answer the question regarding the extractors, yes, the extractors are different, and a G20 extractor will not work in a G21 slide. The only difference in the barrels is the width of the barrel hood. There have been several reports of unreliable extraction from "standard" G21 slides with the 10mm conversion barrels; however, most who buy the much more expensive long slide report 100% reliability. (Of course, it could be that somebody who'd spent that much money on something that didn't work would be too embarrassed to admit that it didn't work, or didn't want to spoil chances for a resale.)  |
Well, Tamron, it looks like you've got a case of alligator mouth and hummingbird ass as you don't know what you are talking about!
First, I am the Colorado Glocker who developed the G20L and during my development I tested all sorts of Glock large frame extractors. I can tell you that the G20's extractor, while slightly different in fit (on the outside), will work just fine in a stock G21 slide. However, because it just gives no advantage over the 45 extractor, there is no need to buy one. How do I know? I tested them. Tamron, do you know the details of the differences? Didn't think so. So how then do you know a 10mm won't work?
I do know and the 10mm extractor has a 0.025" deeper web design used in a slide with a 0.025" deeper extractor cut. The pad to 'claw' length is the same in both the 45 and 10mm extractors so installing a 10mm extractor in a G21 slide just results in the outside face of the extractor sticking out from the slide about 0.020" more than the 45 extractor. The 'claw' position is the same relative to the firing pin for both the 45 and 10mm extractor in a G21 slide.
What really increases reliability is the 'claw' angle change Glock introduced with the LCI design on the right vs the vertical design of the older, flat sided extractors on the left. The canted 'claw' increases the grip on the case rim.

Second, while it is true that the some have had extraction issues with the std slides, I'm not aware of any with the longsides. As I developed a longslide and gave assistance to those making longslides, I've limited my comments to longslides. To date, I have shot just over 4,000rds of 10mm through my 45-10MM barrel in my longslide and you know how many extraction problems I've had? Zero! That's right, not a single one.
During my development, I did testing on lowering the pad on my G21 extractor 0.020" to allow the 'claw' to reach farther into the slide. I got the same results as the stock 45 LCI; zero extraction problems so I decided that the modification wasn't necessary for the longslides. BTW, how many rounds of 10mm have you shot through a 45-10MM barrel in a longslide? How about a 45-10MM in a stock slide? I'm betting you've never even seen one in person, let alone handled it.

Modified pad showing increased 'resting' depth on an empty chamber:
The only issues with my longslide were when it was new and concerned feeding issues because of the sharp corners and tight chamber on my 45-10MM barrel. Once I polished out the feedramp and chamber and 'broke' the sharp corners, I've had good success with it. And, as you can see below, the match size chambers in both the Jarvis and KKM barrels provides for much more chamber support, especially in the 6 o'clock position providing for an extra margin of safety when shooting hot loads and reloads (both of which I do almost exclusively as I reload all my ammo for everything I shoot).
Comparison of the 10mm size diameters between my stock Glock G22 barrel on the left (a 40s&w has the same diameter as a 10mm, it's just a shorter case) with my custom KKM 45-10MM barrel. Note both the tighter chamber and better 6 o'clock support.

Comparison of 45acp between my stock G21 barrel on the right with my custom Jarvis 45 barrel. Note both the tighter chamber and better 6 o'clock support.

So, as we can see, hearsay isn't necessarily something one should rely upon, let alone pass on. Facts, established by inspection and testing, form the basis of my statements, facts.
Third, implying that I withheld issues with my longslide to increase my chances for resale are absurd in that if I were having problems with it why would I keep spending money on it to customize it more to my liking? i.e. I've replaced the plain Bo-Mar front sight with a Dawson FO to aid with long range shots and recently upgraded it's look as stated above.
Forth, stating that, "Having a long slide, particularly a long slide with a conversion barrel, rather than a barrel for which the slide was designed, using a "makeshift" extractor..." just proves your ignorance of the conversion barrel design and your lack of understanding of the project.
I'll admit it, I have right at $2,000 in my G20/21L project; what with testing on various extractors, the slide, 2 barrels, new front sights, extra mags and +2 bases, magwell, hard chrome, etc., etc. It's not for everyone, however, I can more safely shoot my 'nuclear' loads out of my stronger, tighter barrels than anyone would consider in a stock Glock barrel. Don't believe that? Call Kevin at KKM and get a lesson in the chambers and relative metallurgical strength of both his and Jarvis' custom barrels compared to Glock's.
To conclude, I did my project, as did warrior23 did his, because I wanted it and decided I could afford to develop it.
I for one, don't give a damn if it is "...of interest to you..." or not. If you don't like it, fine, have some courtesy and keep your mouth shut. Running your mouth about how something is a piece of crap and doesn't work just because you don't have one is bullshit and makes you look like a loudmouthed ass (which I'm sure wasn't your intention).
I'm sorry for the rant, but I just can't stand some know-it-all pontificating on something he has no first hand knowledge of and demonstrating same by spouting factually incorrect statements mixed with his "so what" opinions. This post was started by warrior23 because he was proud of his pistol (as he has a right to be). Tamron should show some respect and allow him to post his picture unmolested.
