To recap: The lighter recoil spring didn’t work, obviously.
So I took this: 
Cut it away from 10:00-2:00 to allow the barrel to clear. 
You can see the barrel when the slide is cocked back, that it doesn’t contact the Concussion device. 
I am a doctor, not a machinist so it isn’t pretty. So now, I hope I can make this : 
Look like this again:  ????????

Pretty good work, Doc! Are you a neuro surgeon ? ;)
Looks like the muzzle could have just been completely chopped off. BTW, great photos! |

I had my can attached to the rig so I shot in the back yard right after work. Then I decided to cut. Lol. I used the sander to smooth out the edges so I wouldn’t get cut. I might hand sand it with finer sandpaper but I just want it to work. |

The barrel, out of battery, should clear the upper front portion of the modded/chopped CD. I would also encourage CDR_Glock to double check the rear upper portion of the CD to make sure no contact is being made with the barrel, out of battery. It is about a 1.5 cm point of wear in the long axis.... Do you think I should just lop off the rest of the muzzle on the concussion device? I haven’t reassembled it, yet, and I have to work today so it wouldn’t be an issue to take off the rest. |

In summary, I tried different brands of ammo, but the Roni as it stood, was not working with the suppressor. It was OK without a can. Thanks to Solscud for his YouTube video to give me the idea, and LOS from AR15DotCom to suggest cutting what I cut.
You see the rub point on the dorsal barrel margin. 
I took off the excess steel, but questions were raised if the barrel would still contact the concussion device. 
It was not pretty, either. 
I mounted it onto my Bench vise and I let the dremel have its way. Because of the protruding end of the Concussion device I was just going to cut it first, then trim the edges. 
I sanded and polished the near finished piece. 
The daunting task of reassembly was intimidating. 
Because the rail screws did not loosen I did not bother removing them. I placed the detent spring of the rail release and pushed the parts together, and I hammered with a plastic mallet. 
The rest was easy 
I now have clearance for the barrel.

Doc, Your the man... looks great, I take it your going to add a suppressor? Absolutely. It is the only reason I did all of this: Added a 10” barrel, changed the recoil spring to a 13# on a SS Guide Rod (I also have a 15# waiting if it doesn’t work with my loads), and did the dremel work.  .It was pretty rough before I did some minor magic, as you can see from the parts cut. It was hard to cut the barrel end of the Concussion device with the wider part overhanging, so I had to hack it off first, then I worked on smoothing out the ugly parts. Of note, the G17 has more options for springs down to 11#, I believe in smaller increments. The G19 only had 15 and 13 from what I could find from Rock Your Glock... it was also Christmas so many parts could have been sold out... So after all of that mess, I went from this:  
To this finished part.
I don’t have a 17L so I can’t answer that question. I would have loved to have one, though. |

So it works but it was having issues with failure to return to battery by a few mm. Since I have only 13# springs in it, I’m going to up it back to factory springs...I have 15# springs, too.
I hope this will be the last thing to make it work. |

May be the weight of the can combined with the length of the barrel (acting like a cantilever) causing the barrel to prematurely tilt forward before the slide goes into battery.(?). Install the factory spring set and see how it functions.

Somewhat bummed as I received a reply from KKM today regarding my inquiry for a custom 7” threaded barrel. I was informed that the longest barrel they make for a G19 is 6.20”. They didn’t explain or give a reason why the max length is only 6.20”.
I replied and informed them that the G19 was going to be a dedication pistol for my micro Roni and that the barrel length had to be 7” to extend beyond the Roni muzzle in order to host a suppressor. I asked if they could make an exception. I’ll wait for their reply. If KKM can’t make the barrel, I’ll contact Barsto or another reputable custom barrel company. |

Quote HistoryQuoted:
I would really like to see the current set up work for CDR_Glock but I think the weight of the Can extended so far out, is the Villain. I really want this to work with the Can. If it doesn’t I will likely buy a 7.5” barrel. It would cost as much as cutting and threading my 10”. I switched to the factory spring which is heavier. It has a more positive closure and return, unlike the 13#. Factory is usually 18#. With other Suppressor hosts, I realize I have to experiment with different recoil springs for reliability. I’ve done it with 45 ACP, 9 mm, 22 LR pistol, 22 LR Rifle, and 300 AAC, already. If it works, great. If not, I’ll get a CZ scorpion or SIg MPX. But if it does work after all of this, I’ll be pretty proud of the work as it has been a learning process. I’ve worked on my other firearms, like my Mosin which is now an Archangel and have assembled a few ARs. It’s all trial and error, but a lot of error, for now. Tomorrow will be my last trial...I’m hoping. |

Well I had today off because it’s SATURDAY!
I tried 18 and 15 lb springs with no luck. I used different magazines. I tried two different subsonic rounds: 147 grain, and even tried supersonic. With the can, this doesn’t work. Could be the weight is what I’m guessing. Worked without a can with all ammo. Not sure if I need to cut more of the Concussion device. I really don’t want to have to cut this barrel. Any final thoughts before I give up on the 10” barrel? LOL |

Get a smaller, lighter Can. Lol. Seriously, you’ve done a great job on the Mod and I think you’re spot-on on your path to ruling-out the issue. This is a 45 ACP can with 9 mm adapter. I am in waiting for a 9 mm can but I only put in for it in October. So 9 months away... Yay!!! I have 4 Suppressors with one integrated into my Mark IV Ruger. So suppressors have become a passion for me. If it weren’t, I wouldn’t be pursuing this labor of love. The size and weight of the can has to be a factor as it shoots without a can perfectly fine. I know the action with the can has a lot to do with what is going on. Different loads did not make a difference: Supersonic or Subsonic. Tried 3. Tried different magazines, also to rule that out. I’m getting two shots off with a factory spring so I put that back in. The lightest spring cycled but didn’t return to battery. The mid weight spring had FTE. The heaviest spring 18# cycled but only 2 shots at a time. I cannot upload a video but there is still another rub mark in the Concussion device 12:00 position. I’m thinking of two things: Use a dremel and sand away the inner chamber since the barrel still hits the Concussion device or just lop off the Barrel like protuberance altogether. I’m fortunate to have a 3 day weekend. I want closure on this project but it will likely take much longer. I didn’t get into one of the most competitive medical specialties by a lack of tenacity so I will continue until I have exhausted all measures. I do feel like I am close. Thank you, LOS, and I hope you find your barrel. |

If the barrel is still making contact with the CD, remove (dremel) material from the upper inside diameter [12 o’clock] of the CD. In other words, make the upper ID of the CD some what oval shaped. Hopefully that will resolve your issue.

Well I used my Dremel to take material from the inner diameter. Unfortunately, I won’t be able to remove the barre since one of the screws was stripped. Oh, well. It still works without a can. I’ll test it tomorrow to see if it works with a can. A friend mentioned a Recoil booster but I don’t know if I can acquire one. |

I cut the inner diameter but it still contacts the barrel.
My screws stripped so I though I was dead in the water... 
This screw bit set actually worked so I was able to get them out. The screw holes aren’t wearing out so far. I e disassembled it about 12 times. I do plan to buy new screws as the heads strip. I am cutting the concussion device as it makes contact with the barrel. 
The added weight of the Suppressor interferes with the dynamics of the slide. Any contact with the concussion device is affecting cycling.  
My dremel overheated so I’ll come back to finish the rest. Sent from my iPad using Tapatalk Pro |

I received a reply from Barsto, today. STRIKE TWO. Here’s what they had to say about ordering a 7” barrel..:
“First that is extremely long for the G19 and will not shoot well at all even if (not sure you could get a 7" through the slide) could get the barrel tipped through. We would do the 6" but would not do a 7".” |

I've been watching CDR_Glock's posts with interest and dismayed the problems continue to maifest despite the continued mods. I've got a 17L barrel on the way with the intent of using it in my Roni. I took my G17 Roni apart and installed a pistol with the slide locked back. This revealed the angle of the barrel relative to the shroud. It appears that the barrel will hit the shroud no matter what. So LOS's recommendation to take away material from the 12 o'clock looks like the only viable option if an extended barrel is used. Without the shroud the two Roni halves are not secured though . .

I think material has to be removed from the upper rear ID portion of the CD/ Shroud. When I take my barrel out of battery, I can see the tilt/angle of the barrel would easily touch the upper rear of the CD, if it was longer.
simply_ green, I can see that in your last photo. |
