Sticky 629 chambers - Page 1

Posted: 5/3/2021 11:47:03 AM EDT

I fired my new to me 629 V-Comp this weekend, which allegedly only had 3 rounds fired through it prior to me purchasing it. 1 at the factory (fired case in the box) and 2 by the previous owner. I was shooting some PMC 240gn JHPs that I've had on the shelf for quite a while.

Shooting the rounds felt about as I expected a 240gn bullet at ~1300 fps (advertised) would feel like. Not painfully hot but a good kick and muzzle flip while still being very controllable.

But, when I went to eject the fired cases they were stuck quite well in the chambers. I really had to smack the ejector rod hard with my palm, almost resorting to using some tool of mass destruction from my range tool box. Unfired rounds slid in to and out of the chambers with ease. I did not fire any other rounds to see if it was just that load, but will at a later date.

Thoughts or suggestions?

Try some different ammo. I have had sticky extraction with those same loads in my Mt gun. They are the only ones that were tight.

Also, I reloaded those same cases with a 240 and a more moderate powder charge, 1,000 FPS. They did not stick.

There are many other tutorials on polishing revolver chambers online.
That would be MY first step, and troubleshoot from there.

I wouldn't use a Dremel. I have taken a worn bore brush, wrapped it with a large patch coated with polishing compound, and chucked it up in a battery drill and gone to town.

I would also take a good look at the chambers of the "new to you" .44, and see if maybe it had a diet of .44spl in its life, and left some rings in your chamber that need a good cleaning.

Look in the chambers and make sure there isn't a ring left from 44 specials being fired in it. I know you say it's only been fired 3 times, but people don't always tell the truth. When I worked at an indoor range we had 357's that would get a steady diet of 38's and when someone would shoot 357 out of them it would do exactly what you are describing.

I’d do a little hand polishing with some Flitz before I’d use any sort of machine. A patch on a tight fitting jag is what I’d use.

I got a well used Model 19 that did this - very sticky once fired but unfired ammo just fell out. I had a very slight ding on the chamber mouth, and this was all it took to make them stick, hard. A little work with a fine file, and its smooth as silk now.

I'd clean it well and take a real good look for any imperfection with a bright light.

I'd clean it real good before doing anything permanent. I have the same gun and fired the same rounds through it with no issues. If ammo is still sticking I'd send it back to S&W for repair. A performance center gun should not have tight cylinder chambers.

I see "Performance Center" guns, straight from distributers with the same amount of flaws as run of the mill S&W's.
PC is just a name at this point, the guns have different features but are screwed together with the same amount of QC no more.
Up until say 8 or 12 years ago I considered a trip to S&W for modification or repair to be a safe bet but no more.
Only revolver smiths with solid reputations are suitable imo today.
Polishing chambers is an easy task for any somewhat mechanically inclined human but multiple reputable smiths will do it for you, much, much better than the S&W mothership will. Sad but true, driven by price.

800 grit flex hone with lots of oil. They make a 400 grit, but I've been hesitant to use them. I have them for 357, 44 and 45 and they've all helped sticky extraction issues. Just chuck it in a drill, go slow and don't run it out the end of the chambers.

Also make sure the chambers are bone dry. People often mistakenly lube the chambers, which creates a sort of hydraulic resistance and causes sticky extraction
