Default Sear disconnect lever

Is it absolutely necessary to push down the sear disconnected lever to field strip the weapon? The reason I'm asking is most of my semi autos are glocks. I guess old habits die hard. I forgot to push down the sear disconnect lever and pulled the trigger. The slide popped off the frame easy enough. I racked a couple of rounds by hand . Everything seems ok. Anyone got anty info on this?

I believe the lever is an alternative method to the trigger pull.

I always pull the trigger to release the slide. To state the obvious, make sure your weapon is cleared 1st.

There's plenty of threads on this subject. When S&W was getting ready to design the M&P series they did a bunch of focus groups with potential buyers of large numbers of handguns. Those potential buyers were extremely sure that the words "Pull the trigger" did not belong in field stripping instructions. The sear disconnect lever makes NDs while field stripping virtually impossible.

It's your gun, also your house, various body parts and other possessions. Should you teach anyone to handle any M&P DO NOT do the "pull the trigger" thing. There's this concept called vicarious liability that makes you responsible should that person(s) get sloppy. [You don't really think they're gonna own up to not checking the chamber do you? Whashisname taught me to do it that way!]

It's not necessary, but it's also not hard to do. I just reach in with my pinky finger and flip it down with my fingernail.

WR More, gotcha!
Rodspade. My Fred Flinstone fingers won't allow that plus I cut my nails short or chew them off. Edit: I'm getting the hang of it.

I have three M&Ps with over 23,000 rounds between them. I've never used the trigger pull method. I stick the hollow end of a cleaning rod over the end of the sear disconnect lever to pull it down. A retractable ball-point pen will work as well. Takes all of two seconds. However, if you're willing to accept a possible negligent discharge in order to save two seconds, by all means pull away.

If you have gotten to the point where you might be looking at the sear disconnect lever, it will not be possible for you to still have a round in the chamber anyhow.
My method is as follows: retract slide so it locks back, remove magazine, flip the slide retention lever to enable slide removal, release slide to its normal location, pull trigger, remove slide.
Notice that after the very first step, it will not be possible for there to still be a round in the chamber.
I just don't see a rational reason for people to fear pulling the trigger on a gun that is obviously empty. Why do we advocate dry fire practice? Isn't that just as dangerous?

Almost correct, but not.

What happens when they miss this step? Yep, they load another round when the slide is let forward. Then, when they press the trigger, the gun fires.

Not only is it possible to have a round in the chamber when removing the slide, but it has happened at least a few times. I've seen it myself.



As someone has said, your house, your gun, your risk, do what you like. Using the sear disconnect makes it impossible to fire the gun because the striker will never be cocked. If you choose not to follow this step, just be ready to destroy whatever's in front of the muzzle.

It won't hurt the gun at all. I think the reason why Smith added the disconnect was to prevent accidental discharges with pistos with their name on it. Using the sear disconnect lever forces the user to open/lock back the slide therefore ensuring that the chamber is cleared. Its no secret that many accidental discharges happen with Glocks.

Dropping the sear is for sure the safest way to disassemble, pulling the trigger will also release the slide. I drop the sear on the Smiths but I also own a few Sigs and Springfields and they require a trigger pull to drop the slide. If after dropping the slide, clearing the chamber and then checking for a round,there should not be a AD, however, I have no doubt it happens if a step is missed. Just picked up a Kahr cw9, it requires the trigger pull to release also.

The lever is *not* an alternative. It *IS* the factory approved method of takedown. If you choose to "trigger pull", then that's your choice. If you observe all of the safety protocols, then I see no issue with it. Bear in mind that some of us are constrained to state compliance laws that dictate things such as magazine safeties. In those cases "trigger pull" is more complex. It's always an option but it not standard practice.

Any one who can't safely disassemble a gun, that requires the trigger to be pulled to do so, should not be allowed to own a firearm in the first place.

Ok guys, let's dial it back a notch or two. My OP question was for information finding out if the gun is damaged by forgetting to lower the sear disconnect. I plan to go by SW directions as stated in the manual. Period! Please don't get in a heated argument over this.

A logical evaluation that I concur with. I do plan to use the sear disconnect henceforth.
Thanks for you comment.

Exercise good gun skills and make sure it's un-loaded. Pull the trigger. The sear disconnect was designed by lawyers. You don't need to use the Lawyer Lever just like you don't want a Hillary Hole.
