TM G19 Gen3 & Gen4 about to be released.
These are not residual stocks from distributors (like the G17 Gen4 and G18C). These are newly produced batches. TM has sent the release / order sheets a couple of days ago.
TM official website release calendar has not been updated, that is all.
TM G17 Gen5 will come up some day, like nothing happened.
Reason of the "delay" is said to be the plastic materials price increase. Lots of other toy makers had such issues lately.
