I should clarify- it’s almost brand new (I’ve put around 100 or so rounds through it). Also replaced the stock rod/spring with an aftermarket captured rod/spring assembly from Galloway Precision) after the 1st range trip)
I have the installed captured spring as well. Installed it after the first range trip.Give the chamber a really good cleaning with some solvent and a wire cleaning brush and then do the drop test (no not the gun). With the slide off, with the gun pointing down, drop a round in the chamber. It should under it own weight, slide right in. Then point the gun up and it should fall right out. If it doesn’t, keep cleaning.
I too installed the Precision captured spring, and it works quite well and much easier to assemble than with the stock spring.
I have the attached barrel (CA) version. Almost impossible to get a pic of the top section of the chamber. Stupid question: does the firing pin strike the rim @ 12o’clock?See if you can get a photo of the top of the chamber. I have a barrel off a pistol and it is still hard to get the light right. Phone cameras are hard to hold one handed and focus too. 1917
I’m going to the range tomorrow morning- I’ll try to manually load the ammo, shoot it, and inspect the casings.One thing you might try when you get chance is inspect each round before firing. Then manually load the round without using the mag and then inspect the spent cases, especially any that hang up. That will rule out the mag and feeding into the chamber as causes of the rings. The marks are not normal nor are cases being stuck inside of a clean chamber. I hope the other thread posters with similar complaints of the new QD are looking at this. 1917
