From what I've read on here, the factory 19 barrel is not drop-in for a 23/32, like the 23/32 are for each other. I saw a member in the parts for sale forum selling a 19c factory barrel, and he states it will work in a 23c or 32c in his add. Out of curiosity, I swapped the barrel our of my spare 19 slide into my 23c slide, and it seems to fit/function fine; I did not chamber a round, but it feels no different than with the 23c barrel installed when racking the slide. Is this combination possible? I opted to buy an entire G19 slide over an aftermarket conversion or factory 19 barrel as it was my understanding I could not do this. Any input is appreciated. If it will work reliably, I might have a complete 19 slide for sale soon EDIT: I just cycled two rounds, both chambered and ejected with no issues.
