So, I'm currently selling my G33 (the thread is here 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.
