Have a gen4 G17 that a little over 10 years old. About three months ago I got a rmr cut and dlc from battlewerx.
Since getting the cut and mounting a red dot, 508t abd 507comp, I have been having odd failure to feeds. As the slide goes forwardand picks up a round, I would sometines have rounds go nose high and jam against the top of the chamber. But lately, I mainly get rounds that go nose low and the round somehow gets stuck between the feed ramp and mag, and the feed ramp cuts into the nose of the bullet.This doesnt happen every round, maybe 5-10 rounds out of 100. The barrel is the original that came with the gun, the mag body and follower are the original with TTI +6 extension with new springs. It has a GS Pure Tungsten guide rod with 15 spring thats about 2 years old. One note, i did try the factory guide rod and had the same issue. It has a overwatch poly dat with ghost 3.5. Pictures of the nose low jam with Blazer 115. The sheared tab at the top of the bullet is what went under the feed ramp, and I believe the nic at the the bottom is from the steel inner sleeve of rhe mag. This only started after i got the slude back. But, I dont ser how it could be the optic cut. As far as I can tell battlewerx cut doesn't let the screws go in to the internals. Other than trying new mag bodies and followers, i am out of ideas. Its not me limp wristing before anyone suggests that.    |

The right side mounting screw for the optic might be too long and bearing against the extractor plunger, which is preventing the extractor claw from moving to let the case rim slip under it, thus leading to the feed issue.
Remove the right side optic mounting screw and see if it resolves the issue. |

Start with what’s new (slide milling) and work back from there.

+1 on right optic screw. I experienced issues on mine when I first mounted an optic. Swapped screw on the spot and it's functioned fine since.

I did consider the screws, but, battlewerx uses screw posts. So i dont believe the screws are making contact with the extractor plunger. I can take the extractor plunger assembly out with the optic mounted.

Make sure that the extractor tunnel is not full of blue loctite. I bought a used slide off the EE and the tunnel was full of loctite.
Also shoot 124gr rds and see how it does. My 17 with optic does not like 115gr rds anymore and try a new mag before switching ammo. |

Extractor plunger channel is clear. The screw hole didnt break through.
Mags are the only thing left.  |

I would try a factory recoil spring assembly with a Glock 17 round factory mag. I suspect the added weight of the RDS and after market recoil spring has thrown off the timing. Adding the + extensions on to your mags can not present the cartridge fast enough if the cycle timing is off. Any time I see unusual malfunctions I revert back to factory parts and magazines. If the pistol still has malfunctions you can then go through a process of elimination of potential parts to try and identify the cause.

I've told you - you got a bunch of non stock parts in there. Go
100% oem (except slide + optic) and it will run |

The only thing I’ll change on a Glock: + Add night sights + Mill slide for RMR + Add optic Everything else is left stock. Most of the Glock problem posts are on guns with aftermarket parts. |

Reloads or factory? Weights? Gun is ten years old, round count?
Another vote on stock and add one item at a time. More likely to be recoil spring and mag spring. |

I'd say try stock mags and/or stock mags and stock guide rod. I personally don't think it's your optic. I've had several guns cut for optics and never had an issue, but you never know. I've heard mixed things about TTI mag extensions, and some other mag extensions, especially +6. Mags and guide rods are simple and quick things to check, so I also vote to start there.
I ran a ramjet and RMR on a G45 with a new optics cut right after I got it back, never tested it before addding anything. I also had a screw too long for the RMR that was capturing the extractor plunger and it ran 100% with an extractor with no tension. No other parts added. Factory mags with low round counts. |

More likely to be recoil spring and mag spring. Factory Blazer brass 115gr. Dont have an exact round count, but I shoot fairly often. At least 15k rounds on factory slide and frame. Wouldnt be surprised if actual count was 20k+ |

You mentioned a +6 mag extension…
Are you using the factory G17 spring or extra power spring? |

So both a comp which can retard function) and a red dot which adds weight plus a refinished slide ( potential issues with channel liner if not removed prior to refinishing or an improperly installed replacement plus mag changes.
Where to begin? As mentioned return to as close to stock as possible. If it functions start adding the items most critical to you ( I would say red dot) and if anything reintroduces the malfunction, take it out and accept where you are at that point. |

This is the last thing I would even consider I think the main issue is the +6 mag extension and if, IF, OP is using a factory spring, tube, & follower but with the aforementioned +6 extension. Maybe it’s not the issue, maybe it is. I’d want at least a +10% power mag spring with a +6 extension. @PhilDNice - Did you buy the +6 baseplate directly from Taran or did you do a little horse trading for it? If the latter, did it come with the extra power spring? Either way, that would be the first thing I’d look at. I’d either ditch the +6 and run complete factory mags or buy a new +10% magazine spring from Wolff or Ghost (or whoever else). |

Sent it to glock, they replaced the extractor, back plate, striker safty, trigger bar w/ shoe, connector, and magazine. 350 rounds and so far its feeding 100%, but its clipping off the nose of the bullet.
New mag, new internals. Glock suggested trying different ammo.

Odd, can you see where that's happening in the pistol, I'd imagine it's depositing a bit of copper rub wherever the bullet scraping is occurring. Maybe a burr on the feed ramp or chamber mouth of the barrel?

It looks like the bullet is somehow catching the bottom of the feed ramp, and the edge of the feed ramp is shaving off the bullet tip.

Have you tried without the RDS? That's a bigger sight than most of the rmrs use, and could be causing the timing issues that were mentioned.

I can try it without the optic. But, the optic is 1.7 oz, and the rmr is 1.2. The acro is heavier, but I havent seen any issuse similar to this related to acro.

Standard OEM barrel with 508T should cycle fine. Mine does with std barrel and OEM threaded. I'm also using 124 gr fmj for practice (Magtech and Federal).  |

When it does work does it throw the brass with authority?
Try a new mag as they are cheap but it might be the changed mass of the slide, do you have a scale to weigh it vs a stock one? |
