View Full Version : Esoteric Glock Conversions

So, I'm currently selling my G33 (the thread is here (http://thefiringline.com/forums/showthread.php?t=439987) if you're interested) and I plan to upgrade to a model that can be converted to some of the more unusual cartridges.

I'd like to be able to shoot .40Super, 9x25 Dillon, 38Super, etc....

Problem being, the gun that best fits the bill for me overall, the G30, doesn't allow for hardly any of these conversion options and my next choice, the G29 isn't much better.

Now, for the question(s)...

I see that G21 barrels (45acp, lots of conversion options) are not listed as working in a G30 (45acp, almost no conversion options)...

I see that a G30 slide will fit on a G29....

I see that the frame widths and barrels heights are listed as identical on all three guns.....

So, is this nothing more than an issue with the locking block? Can I just swap the locking block in a G29 to the block from a G21, use a G30 upper and G21 barrels or are there other differences?

If there are other differences, can they be reasonably overcome?

I humbly plead for the sharing of your expert knowledge base.:)

No body knows?


Well, I see from some further research that the internal dimensions of the slide is different from one cartridge to another. There's definitely more to it that that though. There is some sort of difference in the trigger group or locking block also.

Curious why I can't seem to find 10mm conversion barrels for a G21. :confused:

Lone wolf or KKM sells conversion bbls for the G21 to shoot 10mm. They are quite beefy in comparison to the G20, but as a result are much heavier. There are no bbls to shoot .45aco from a Glock 20 or 29 to my knowledge because the slide was drilled for a 10mm bbl, so the conversion bbl would have to be very thinly walled. I cant answer the rest of your question though...
