I have a g23 Gen4 40 cal I have been considering conv to 9mm. It is my understanding that all I need to do is buy a 9mm barrel, 9mm mag and 9mm recoil spring and conv will be ok. Need comments before attempting,
Many online videos (YouTube, et al) will show you how to detail strip your Glock. It is quite simple and you will need to know this in order to replace your trigger housing (an $8 part), which contains the ejector. Read about Glocks! Study your gun's parts schematic (look online if you didn't get one with your gun). One thing you will learn is that neither Glocks nor any of the other modern auto loading pistols use clips, despite what Dianne Feinstein believes. The word is magazine. Have fun and good luck.
