Re: G19/SWR Trident FTF
Guys, he is using the 3-LUG adapter on the AR. He is NOT using the LCD on the AR so the LCD isn't getting fouling from the AR.
Now, the point about cleaning the LCD is valid. However, is sounds like he (the OP) hasn't shot too much through the LCD in the first place. Thus, I doubt fouling is the problem.
Just because that barrel works fine without the suppressor doesn't mean it is not the cause of this problem with the suppressor attached. I've shot THOUSANDS of rounds through my G19s and LCD equipped Trident without problems and without cleaning the LCD. The only barrels I use are Jarvis and KKM though.
All aftermarket Glock barrels are reverse engineered. Some manufacturer's barrels lock up better than others.
To the OP, see if you can find someone local with another G19 barrel you can try. Or another suppressor. In the past when I've experienced other people's host/suppressor combination not working we always tried to first test a different suppressor on the host weapon. If that still failed the chances were the problem was in the host weapon somewhere. If it worked, we'd try the "questionable" suppressor on a second host. Are these options for you??
If you can't find someone local to help you, I am willing to send you a proven KKM barrel for you to try. You pay the shipping to and from but I'll let you hang onto it for up to a month.
Let me know if I can help.
