I have 2 S&W revolvers with the internal lock system. Has anyone ever had trouble or malfunction with the lock failing or jamming?
 
Never heard of the internal locks malfunctioning. I have a couple of friends that have S&W revolvers with those stupid internal locks, but they never use them

All those are for is to make the anti-2A crowd feel better. My advice is to never use them as they are dumb.

I have 2 Taurus revolvers with something similar and have never used them. I figure if I never use them, they won't go bad.
 
Political correctness has no place in a firearm that is used for self defense. It does not matter if the reports of failure are true or false. Your gun should never be available to anyone that is not qualified to handle it. I would not bet my life in a moment of panic and terror on a device like this. You choose a revolver because when you pull the trigger it goes "bang". No safety, no firing pin blocker, no squeeze grip, no two part trigger. If the round does not fire, you pull the trigger again. You don't need the government to make some one more important than you happy at your expense.
 
I've heard of them failing in the lightweight guns. It's rare but I wouldn't have one on a carry gun. Just no reason to add in junk you don't use that could potentially fail. When I bought my 642 I made sure to get the no lock version.
 
It is supposed to be easy to remove and I hear there is a plug for the hole available from someone on the S&W forum. I don't know if it is a good idea from a liability standpoint. My only Smith is a non-lock 642 from 2012. I would look around on the S&W forum. The locks are highly hated and a lot of people will not even buy one with the lock.
 
The lock works be a tab that stops the hammer . The Tab can be ground off and reassembled to look original but it will not lock
 
I have carried 1 of 2 M&P 340's (lightweight) with locks for nearly 2 years. Into the mts hiking, some fishing trips, and a whole lot of daily carry. Never had an issue with the locks. 1 of mine has a few over 500 357 loads and about 600 38's thru it. The other has 275 357's and 100 38's. So they got rattled a good amount for a little carry snubbie.

I'm not a big fan of any safety on a handgun. There needs to be one single safety, its located between your ears. I had a choice, pick these up or wait for whenever....they became available. Never had to disable the locks (to date any way). If needed it's a pretty easy job to reliably disable. Easier than cutting a spring coil or 2.
 
"Internal lock?" Not on my Model 18 Combat Masterpiece. Going on fifty and as gorgeous as ever. Even have the box and everything that came in the box. Beautiful .22 handgun. Paid about $90.00 and wouldn't take $900.
 
Yeah I have a M586 pre-lock model and it's never going to be sold. But I have heard a few stories on the early versions having issues but after watching a you tube video it's easy to remove.

Any videos on that procedure?
 
If you are confident enough to take the side plate off and remove the parts you will see how the lock works and the locking thing to grind off. You can remove all locking parts but that leaves a hole where the key goes. I did it on two of the J frames I have with a lock and it is easy.Here is a video After he removes the hammer and uses a pick to remove a tiny spring and grips the tit with tweezers to remove the part that stops the hammer. That part is what I grind flush and then replace the part and that holds the other lock parts in place, Not replacing the part allows the remaining lock parts to move in and out,
 
My 2 yr old 686 has the lock.

I tried it once to see how it worked and then just left it alone.

I put about 50 rounds per month thru this gun and never even thought about that lock again until I saw this thread.

The "leave it alone" option is working for me.
 
I remember when S&W introduced the then new .500 Magnum revolver. My local dealer got the first 4 he sold back, because the internal locks all failed, tying up the guns. Luckily all 4 were purchased through Davidson's. They all came with a Lifetime Free Replacement Warranty. I have no idea what the newer .500's are like. I assume they fixed the internal lock problems.

As much as I wanted a S&W .500, I went with a Magnum Research BFR in .500 S&W Magnum, and I'm a happier man for it. It runs like a Rolex.

Is the round cylindrical part that is raised on that piece what you grind off?
 
If you don't know exactly what you're doing it's best to stay out of the revolvers internals.

Just remember that if you live in an area with a anti 2nd amendment prosecutor and you use that gun to defend yourself you open yourself up to an uncomfortable line of questioning on why you made your gun "less safe" by removing a safety device.

I know I saw that article some time ago...and where I live....100% anti gunners so the lock stays put. Thanks for reminding me. Maybe after I move South.

While I live in a pretty solid area for gun rights, it has kept me from carrying a 1911. I like the gun, but hate grip safeties and would too tempted to pin it and deactivate it. With my luck I would get the one oddball that wants to make a name for him/herself.

Sad that there is so much politics in the criminal justice system.

That is extremely doubtful. There have been, and in fact are now, many members of law enforcement who carry 1911's with pinned grip safeties. This is yet another one of those Internet myths that lives on, much like the use of hand loads in a self defense shooting will cause you instant legal problems.
