Glock 20 Gen3 rsa issue

Apologies in advance if this is posted in the wrong section. I bought a brand new Gen3 G20 last week. I put about 50rds of Sig ball rounds thru and it ran as well as my Gen4 G20's. Took it home to disassemble it. As I am taking the slide off the rsa falls out and the barrel almost does but I catch it. I have never had this happen and I own four Gen3 Glocks and 8 Gen4's. So I reassembled the Gen3 20 and disassembled it about 10 times. Half the time the rsa would fall out, the other half it would remain where it was supposed to be.

Is this normal and just something I haven't experienced yet?

 

Thank you! Glad I found this forum

 

I called Glock and spoke to one of the techs I have dealt with in the past and he said that this issue is not uncommon in Gen3 20's and it's a non-issue if the gun runs fine which it has so far. He did mail me another rsa just to check to see if that made a difference or not. Still waiting for that rsa. The tech said he'd send me a pre-paid shipping label to take a look at my 20 if I wish. So I guess we'll see what happens with the new rsa.

I have put another 100 rounds thru the gun with no issue whatsoever. I suppose it must not be a major issue if the gun still cycles fine. Do you guys see an issue with me continuing to use this G20 the way it is?
