Exclamation Shield 9mm slide automatically locks back when racked back

Is it normal for the slide lock to automatically engage when you rack the slide back with an empty mag inserted?
And will it do that with a loaded mag inserted?

I'm guessing this is your first semi automatic handgun, yes it is perfectly normally to lock back on an empty mag and no it won't do it on a full magazine.

Yes that is normal. To understand what is going on, look at the magazine follower and on the front left hand edge is a notch.

That pushes up on the slide lock lever, when the mag is empty, and that is why the slide locks back when an empty mag is inserted.

Will the slide still lock back with a loaded mag ? No... with a cartridge there in the mag on top of the follower, it can't contact the slide lock lever.

That's why the pistol will cycle and fire when the trigger is pulled until the mag is empty, and then the slide normally locks open.

When slide lock occurs you have an empty mag. You can drop the empty mag, insert a fresh one, and pull back slightly on the slide to release it and load a round from the new mag. Most semi-auto pistols function this way.

Welcome to the Forum, now please enroll in an introduction to handguns course, Google for a training facility in your area.

If you happen to be in east central Indiana PM me and I will get you set up.

Investigating a local NRA intro course would be appropriate. My range offers one once a month, and yes, they do understand that some come as new shooters with a weapon already purchased.

Asking questions is never a bad thing, but the answers may not be what one is looking for.

Thank you for being willing to come here to Smith & Wesson Forum to ask this question. Good for you to make the effort to learn more about the pistol and there is nothing ridiculous about making the inquiry you made.

We don't all assume you'll shoot yourself because you didn't know about this feature of the pistol. We all don't feel the need to belittle others in some mistaken belief that we'll look like we're some sort of smarter, more savvy shooter for doing so.

You are invited to come here on the Forum any time and pose any shooting question you might have. Good folks are here who are helpful to others who seek a better understanding of things related to firearms.

Let us here from you again when you've gained a shooting impression of the Shield.

I think you got the right answer from Gunhacker; yes, normal.

I also wanted to offer a warm welcome to the forum. I'm new to guns also, nothing wrong with asking questions. It's how you learn.

Welcome to the forum from North Carolina. I think overall you will find this to be a very friendly forum. This is the internet and there are always a few that will not measure up to those standards. We don't put much stock in their comments.

Well as a newbie gun owner myself (just purchased the M&P 9c a month ago) I was reading my instruction manual and getting familiar with my gun. I realized the same thing as the user who started this thread. I googled and found this forum that answered my question. No question is a dumb question and thanks for asking because now I know.

For anyone that wonders my new shooter class is scheduled.

Glad I found this forum as I KNOW I will learn a lot from it.

Each type of weapon will have what is frequently referred to as a "manual of arms". This is how a particular gun functions with regard to loading, unloading, making safe, etc. Many are similar, but not all are the same. Your owners manual will contain this info, but if there is anything at all that isn't clear, just ask. There will be responders with more experience who are eager to guide you and won't tell you you are an idiot for not knowing intuitively. There are no dumb questions except the ones that aren't asked.

+1 to what epj said. Most experienced shooters are happy to share what they know, and most of us know that almost every firearm has something unique or at least a little different about it.

I work as a Range Safety Officer and will often talk to people about their guns to learn and to give them an opportunity to ask me something they might be wondering about.

Ask away, and congrats on the new pistol and hobby!

You can always press the slide release button, located on the left side....forward of the ejection port. It is very hard to operate (Mine is after 3 years!)!!!!! BobK
