? S&W Mod41 Technical Question - Bolt Irregularity
On my 4 month old S&W Model 41 (700-800 rounds,) I have noticed a small "bump" rising above the surrounding surface at the rear underside of my bolt (see pic.) Maybe a welding spot?? There is a corresponding elongated mark running up the face of the hammer. So, the "bump" is the bearing point as the hammer is cocked.
Should I smooth this "bump" out - say, with a Dremel followed by fine paper? Or, should I just leave it as is?

I normally use a thin film of grease on my center fires where the hammer contacts the slide. It helps it slide with less friction when it comes back. Unless the slide is very hard you will have it and there is not much you can do. I would leave it as it is. It gives you a larger contact area which will eventually get to where it stops. Now if your hammer has a rough spot it may help to smooth it out.

Thanks! Actually, it makes for a smaller contact area. If the bump were not there, the contact would be across the wider area of the bolt. You can see where the contact starts across the entire edge but, as soon as the "bump" comes into contact, it is the only thing touching the hammer and runs up what is becoming a groove.blue68f100 wrote:I normally use a thin film of grease on my center fires where the hammer contacts the slide.

Thanks!
Thanks! I certainly appreciate your attention and response!
As I continue to think about it, the protrusion has not only marked the hammer face but riding up and resting on the hammer could be a contributing (or major) factor in the malfunctions experienced during the 4 months I have owned the gun, i.e., annoying and consistent failures to eject when using SV ammo. It certainly has caused increased resistance to cycling and may explain why the gun has only functioned perfectly when using HV ammo.
Not owning a stone nor knowing how to use one, this has tipped the balance to make me send the gun back to S&W for correction and general attention to the malfunctions. And, of course, I don't want to void the warranty. By the way, this is a Performance Center gun!

Will do! And plead with them to NOT change the trigger which I adjusted and now clicks smoothly at 2 lb 2oz. Hopefully, they can change the hammer without disturbing the sear and trigger.Bullseye wrote:In that case, they will likely replace the bolt and the hammer. I would also mention the inconsistent ejections in my comments to S&W customer service.
R,

Back from S&W
My "new" S&W Performance Center Model 41 was returned from S&W today. Do you suppose they have some objective to drive you crazy? I sent them a full page starting with a summary that mentioned 1-the bump/protrusion on the bottom of the slide; 2- the failures to extract/eject/fully cycle on SV ammo; and, 3- the observed abnormal friction points showing wear on the gun after less than 1,000 rounds. This summary was followed by three paragraphs detailing those findings. In the box they returned was a paper that said,
"CUSTOMER COMPLAINT: EJECTION
REPAIRED: ADJUST EJECTOR"
That's it! That's all they said! When I opened it up, it was apparent that they did stone off the bump from the bottom of the slide. I can't see that they relieved any of the friction points and I can't see what they did to the ejector?? The hammer has not been touched.
I'm not sure when I can get it to the range, with Xmas and all, but I guess the proof will be whether I still have the problems.

Ruger can be vague, too. I sent a Single-Six back to Ruger for a .011 cylinder/barrel gap. I got it back with a .004 gap. The work order said my complaint was "spitting". It said barrel and pawl "repaired" and listed five screws as "replaced".
I know they rebarreled it. I assume they also found less than perfect timing, so that meant a new pawl and frame screws.

As Ruger22 stated, I experienced the same vagueness with Ruger a while back when I sent in a MKIII. Everything turned out fine for me, so try not to get to far ahead of yourself, I know I was jumping to conclusions, when in reality everything was fine. Like you said, you will have to wait until you get to the range. Hope it all works well for you.

Range Report
My Mod 41, fresh back from warranty work at S&W, went to the range today. At first, I was in a panic - the first magazine, with 5 rounds of CCI SV, required manual ejection and feed with every round! Then, I recalled that I had re-installed the factory 7.5lb recoil spring before sending it in. Luckily, I had brought the 7.0lb Wolff spring with me. I put it in the 41 and never experienced another glitch of any sort for 150 rounds!
