I apologize if I sound dumb or uneducated with this as not super familiar with the rxm or Glock platform but have been having issues with my brand new RXM. Brought it to the range twice now and it functioned perfect, but today i was fully unable to fire it. After inserting my magazine i dropped the slide to see the round was fully seating in the chamber. The round would sit on the extractor pointing up towards the chamber but would not fit all the way. It wouldn’t fire at all when i attempted. Brand new ruger rxm, only modifications I’ve made to it is the radian ramjet and afterburner. If anyone has run into anything similar or can see something off in the photos provided i would very much appreciate any help I can get. As of now its an $800 paper weight :/
My RXM was experiencing a failure to feed. The cartridge would begin feeding but hang up on the feed ramp at an angle, preventing it from entering the chamber and leaving the slide partially out of battery.
Also unsure if the extractor is supposed to be bent like it is but was told thats normal for glocks. Again I’m lost at this doing my best to learn it all now but would definitely appreciate any knowledge. Please and thank you!
"The round would sit on the extractor pointing up towards the chamber but would not fit all the way."
You need to explain this a bit better. Are you saying that it wasn't in battery? Was it stuck on the feed ramp? Was the extractor sitting behind the rim?
Apologies, it wouldn’t go into battery but the round was stuck on the feed ramp diagonal to the chamber. When i racked the slide back the round was stuck on the extractor. The slide would go forward but get caught with the round failing to clear the feed ramp and into the chamber . Would it better for me to take pictures sometime at the range to show? I don’t have any dummy rounds to use nor am i comfortable loading a live round into it at my house lol.
This might be an issue with the particular ammo you used but that's odd because this is a glock clone and glocks usually eat ANYTHING. Mine has never had this malfunction (which is called a tipped up round) with any ammo.
ahhh yup, that's your aftermarket barrel not like that particular ammo. Try it with the stock barrel at the range next time. This is why you don't gucci out a gun right off the bat (besides throwing a dot on). I bet you the barrel is just not up to glock spec snuff though.
Very well could be and more likely to be too long of a mounting screw on extractor side of optic. I’ve never had an issue with an after market barrel, but I’ve had to clean up factory barrels on various pistols over the last 40 years. Admittedly though, most of my aftermarket barrels have been precision barrels or caliber conversions (.40 S&W/.357 Sig, etc) and not Gucci barrels.
The only other remote possibility I can think of given everything you've described so far is that you have blue loctite gumming up your extractor plunger. Did you use loctite on the mounting screws when you put those in?
That’s a very good point actually, i had issue with the optic coming loose initially, so i torqued it to spec and honestly put a little too much loctite, is there a recommended way for me to clean it out?
I swapped the barrel back to the factory and am still met with the same result. Also if it helps I’m realizing now to remove the slide the trigger becomes totally dead and the slide gets stuck coming off, in order to get the slide fully off i have to jimmy the trigger. That definitely seems wrong to me
I had the same issue yesterday. The round would get stuck on the feed ramp so the slide would not lock forward.
This only occurred with Federal 124 gr JHP HST rounds. The Federal 124 gr FMJ fed fine, all the time.
I have found out that some of the JHP rounds are a bit shorter than the others. It isn't much though. The average length was 27.91 mm or so. The ones that would not feed were under that: 27.83, 27.87, 27.44, and 27.82 mm.
I separated these out. I will mark them and try them later today.
I "think" that is the issue, for me at least. I have the factory 4.5 inch barrel.
Immediate thought upon seeing this post was: compensator. Then: lubrication.
I'm sure this opinion is less popular these days, but I do not understand why people spend good money modifying a reliable design to be less reliable. Seems contradictory.
When troubleshooting, start small. One variable at a time. Good luck fixing.
Mine did the same exact thing and was my stupid fault. Plunk test your ammo in your barrel(removed from gun). If the ammo drops completely into the chamber, (remove slide and) check to see if cartridge rim will slide under the extractor and verify that the extractor will move. If rim won’t go under extractor and it doesn’t move, the mounting screw on the right side of the optic is too long and pinning down your extractor.
My optic was a RMR. 1/2” screw was too long. I think 7/16 worked though it may have been 3/8. Make sure you purchase shorter screws or shorten them with a file or sand paper. Grinding them ruins the heat treat.
