> anyone know if there are any differences in the design of the 9mm one vs the one in this video? biggest difference is the 9mm one is probably using a suppressor with wipes in it. (i believe it's the standard option) if it has wipes in it, think 3-4 rubber discs slotted along inside the suppressor, the first time you fire it it ruptures all the discs and it also creates a lot more back pressure for that first shot that will kick shit out the ejection port. i *think* that might be what people are seeing when they're referring to it venting gas and why it's very visible for the first shot, but less so or not at all for the follow up shots.
