I went the other way with my 23 and 27 rather than selling. For a "9mm" I just bought a stock barrel for a G32. That barrel works in both the 23 and 27 and gives the velocity of the 32 in the little 27. I use Underwood .357 Sig loads here:

125gr Gold Dot at 1475fps. Very close to .357 Mag performance with none of the drawbacks. I'll probably add a conversion barrel for the 27 to turn it into a 26 when I want to shoot cheap 9mm practice rounds. I'm looking at threaded barrels for that.
BTW I have a G31 to 9mm Lone Wolf conversion barrel which has never been opened, if anyone is interested PM me.

Re: Problems with .40 cal.
A lot, I think most, of the Glock problems with the 40 came about because of the so-called unsupported chamber which was believed to be necessary to insure proper feeding of certain bullet designs. Bullet design moved on and Glock redesigned the chamber to better support the case. There was no change in the Gen nomenclature, they just started building with the new chamber. Curiously, others copied the unsupported chamber design that gave some problems. Not surprisingly, they had problems also.
I've owned and shot a G23 and G27 for many years and check every fired cartridge for the "Glock bulge." I've never seen one. I've not ever seen a department with a certified armorer have any issues. Many small departments don't have the budget for an armorer and so they rely on the officers to be their own armorers - usually with predictable results.
The other issue which is not as easy to address is bullet setback caused by chambering and re chambering the same round. In duty loads the 40 powder load is a near compressed load. Push the bullet back in the loaded round and you get large variations in pressure. Quality factory loads and savvy reloaders comprehend this and crimp more aggressively. You still see some smaller houses whose loads will set back easily.
