model 41

[reedybart]

I have a brand new model 41. I had 3 failures to fully seat. I have only S&W magazines. Yet all of my failures were from the same the same magazine. I was shooting CCI sv. I fully believe that the failures are due to something being in the chamber. I was thinking about putting a nylon brush on an extension and spin it with a drill. Is this a good idea or what. All input is appreciated.

Try a little CLP on the ammo cases, just a thin film. Model 41s can have tight chambers, and they also need to be kept clean. If it is new, I wouldn’t get to aggressive with brushes and power tools.

Something in the chamber? I doubt it. Bent mag lips are super common causes of misfeeds. Don't start removing material from a chamber, I let myself be taken in by a well-meaning but incompetant gunsmith who gave me a barrel for Canik that I'm lucky didn't kill me.

Take the barrel off the gun, and see if your .22 rounds will easily plonk. That will tell you if the chamber is an issue.

Send it back. I purchased a Model 41 performance Center. BRABN NEW! You could not rack the slide, you could not move the safety, you could not pull down the trigger guard to dissemble, and there is more. How can this happen and be shipped from the PC. I got it back but have zero interest in it. Worst gun I have ever owned. S&W did everything to make it right, Ill give them that, and I am a S&W collector.

 

[reedybart]

i will try that first

What a good idea. It is supposed to be pretty today, while cleaning the 41 I will try your idea

Your problem could very well be off speck ammo. Today the ammo factories are pumping out ammo as fast as they can and quality control had gone right out the window. Even some of the super high grade ammo like Eley had a bad run of ammo a couple of years ago.

Cheap Walmart mass marketed ammo is notorious for being out of spec. Ammo that is oversize, or has less than a full powder charge is becoming almost normal. I recently bought some Federal Rang Pack ammo that misfired about every 10 rounds. And at one time Federal Ammo was considered one of the better ammo makers. No more obviously.

A dirty gun will cause the slide not to run forward all the way.

A defective magazine. Test with more than one magazine.

A new gun not yet broken in may be stiff and not worn in yet.

A gun with a lack of lubrication plus being new will cause your problem.

Limp wristing your gun will act like a shock absorber and the slide may not snap all the way back causing either jams or not running fully forward.

Underpowered ammo will cause that condition.

Oversize cartridge case will cause erratic ejection or jams or the slide failing to go forward all the way.

A dirty chamber or a rough chamber will cause the cartridge not to seat all the way.

A chamber or barrel throat that is leaded up will prevent the round from being fully seated.

You can usually see a defective roughly made chamber. I recently bought an unfired H&R revolver that had 9 rough chambers. I took a stiff losso blue nylon brush and put on some JB bore scrubber paste and then put the brush in a short cleaning rod and then in a drill motor at low rpm and polished out the chambers and this cured the problem. This is a tricky operation and if you overdo it you can make the chamber or chambers egg shaped ruining the accuracy and reliably of the gun.

Your gun is not broke in yet, keep shooting it and it will be better, if not then you can send it in for repair

My idea worked. I took a nylon bore brush on an extension and spun it with a small drill. The chamber had something in it that prevented the casing from completely. I shot 50 rounds of CCI sv and ro rounds of Federal Ultra-Match with no failures. No I see why people replace the extractor.

A Volquartsen extractor is an excellent! addition to the M41. In my opinion they work much better than the originals and they are not expensive either. Installing one requires some basic mechanical skills, some good old common sense, a hammer and a punch. I've had one in my M41 forever - flawless extraction!

Reedybart, you mention that all of the failures are from the same magazine. Are you implying that you have more than one magazine and if so, are the others functioning O.K? If that's the case then I would suggest that the magazine is the source of the problem and probably nothing more is required than an adjustment to the lips of the offending magazine to improve the feed.

I screwed a nylon brush on an extension and spun it in a small drill and cleaned the chamber. All magazines fed both CCI and Federal sv fine, turned out there was a piece of crud in the chamber itself.

Glad that you found a cure...
