Hi there enthusiasts. I am new to the forums but reading through all the info on here has been a great experience. I already own and love a new G23 Gen4 for which I also have the conversion barrel to 9mm. I use it with the G19 Gen4 0-4-3 RSA and also have a G19 trigger housing(ejector) and a G19 LCI extractor on order. I am now looking to do the same thing with a G27. I already bought and received the conversion 9mm barrel for the G27. First off, where is a good place for me to find the G27 Gen4 in stock? I have availability to get the G27 Gen3 today but thinking of going with Gen4 so I can use the smaller size grip to fit my hand better. Having said that, I don't want to be waiting too long to get a Gen4 though. Ant thoughts on why I should look specifically for the Gen4 instead of the 3? And any help on where you guys/gals know of that I might be able to get a Gen4 without getting majorly gouged? I would even be open to getting one that is lightly used if necessary as long as it has EVERYTHING with it like factory shipped. Thanks in advance.
