PS I owe you that list !

Don't think you are going to achieve that standard with your quest for a blowback action. I'm not really au fait with them and only have 2 which I haven' t really tried to master . To me, both are just plinkers
Possibly a better place to ask this question would be on another forum more dedicated to that type of gun . I always Ignore the kids on the Underage Boys Club one but there is a Replica one that may produce an answer. If you don't want to join, possibly someone on here could ask the question for you. I know that one of the pistol entheusiasts on here is a mod on the latter forum
