Sr9 not ejecting brass sometimes!

[Jorg]

Anyone ever had any issues with the Ruger SR9 failing to eject brass on multiple occassions?
Was at the range and almost every 5rd round or so, it would fail to eject the brass.
It was a clean weapon and it was not poorly gripped when firing. Thoughts???

New or old pistol?
What brand of ammo?
partial ejection or didn't extract at all?
Any tiny marks on the cartridge rim?
Have you checked extractor with mag glass and bright light?

There may be some debris behind the extractor, not allowing it to land fully tight to the frame. Try a good detail strip and clean. Keep lube out of there.

New or old pistol? - New pistol, using it for the 2nd time at the range
What brand of ammo? - walmart winchester 9mm Luger
partial ejection or didn't extract at all? - sometimes partial, sometimes didn't eject

Planning to strip it down later & check.

I use WWB in mine.
After field stripping it, drop a bunch of loaded cartridges into the chamber and then see if they fall out normally. Should be a slip fit.
Probably won't be able to tell much with a cold barrel.
Examine rim of failures to extract under mag glass. Any tiny nicks may be indicative of burrs on the extractor.
Work extractor with your finger, should be firm but smooth. Not gritty.
I would pull extractor. Examine for burrs. Polish sliding surfaces except for the extractor head itself. Very lightly grease sliding surfaces.
Could be just tolerance build up on the extractor, and just needs a break in. Could be hardened factory grease.

If you think it's a chamber issue, bring it to where you bought it and have gunsmith confirm it. Then call Ruger.

Just clean and shoot the gun. Many new semi autos need a break in. I would also liberally lubricate the pistol. 20w50 synthetic motor oil is my favorite for centerfire guns.

I would also keep an eye on the mags. If all the failures can be traced to one mag, it might be the problem.

I did a bunch of things recommended here. A lot of good advice here. After cleaning again and then lubricating it with WD40 liberally I had very few problems. - thanks guys.

happened a few times to me when it was really really new, now after tons of rounds it's been flawless

Big mistake. WD 40 is not a lubricant. The stuff is just about useless except for getting rid of moisture. Synthetic motor oil is much more effective and cheaper.

what Gammon said, i also like motor oil. if its good enough for an engine its plenty good for a gun.

WD40 ??!?!?! It's a corrosive to break/loosen nuts and bolts.

 

[Jorg]

Heard it loud & clear and will pick up some motor oil.

Mine did the same thing with Winchester White box 9mm the first time I brought it to the range. Ran about 100 rounds through it and had multiple problems... Cleaned and oiled it and it hasn't had one since. I've shot more winchester, UMC, Blazer, and Independent through it - about 1000 rounds... Love the gun! I just put a rocket bar in it and it's near perfect now.

WD40 ??!?!?! It's a corrosive to break/loosen nuts and bolts.

it is a Water Dispersant (formula 40) originally made for aircraft use...its not a lubricant or penetrating oil/fluid by any means.

please give us an update Jorg!

Some fishermen in AK soak the herring that they use for bait in WD 40. No legal, of course. Jack.

 

[Jorg]

Thanks for all the tips & the problem was lubrication. I don't think I was using adequate lubrication after cleaning, and now I'm generous with a lot of lubrication and few problems at this time. I've gone thru about 1,000 rounds, and it failed to inject maybe once or twice!

glad to hear you have had success with the SR! loved mine and love my compact
