Release of shield 9 slide

[moxie]

A well trained person who knows their weapon will most likely never use the last round before they reload the mag if they are in a gun fight. The last round will get chambered and at that moment they will drop the mag and reload. This is so the slide never locks open and they never have to fight the release.

Here we're into the difference between the "tactical" vs. the "emergency" reload, concepts best learned through instruction at basic defensive pistol and advanced classes.

Agree, when the gun runs dry and the slide locks back the preferred method is drop the mag, insert a new one and "slingshot" the slide. No touching of the slide lock required.

moxie s&w customer service told me this method also its in the owners manual as well

I just got my shield 9 yesterday. And oh my gosh. It takes all I have to release the slide when it is locked back. Just about takes both hands. Does anybody else have this problem? Or do I need to send it back. I really think it is a problem. Thoughts and or solution? Thanks

I thought exactly as you did when I got mine last week. In fact, I nearly traded it for an XDs because of it. Then I figured I would be kicking myself if I never even fired it. So, I gave it a quick cleaning and took it out today and put half a dozen mags through it without issue. Yea, it's tight, but nothing unmanageable once you get it out and actually use it. I don't see an XDs in my future any time soon.

Releasing Slide gently when magazine empty

My glock slide release pushes down easier the more you push back on the slide taking spring pressure off of it. Again I do not let the slide slam closed when magazine empty.

The second picture down shows the back end of a glock barrel the best.
This one has the remains of a cartridge still in the barrel. Ignore that and look above and to left of the shell where the barrel protrusion sticks back and makes contact with the breach face when the slide and barrel slams closed.
My point here is that this is the best picture I could find of the rear of barrel that hit's the breach face full force when slammed closed empty. Note that it is thicker on the left side - which appears to me to be exactly were the breach crack forms first.

So to me the below is not about the fact that any gun can be blown up with excessive fast burning powder or rapid fire after a squib load. I only wanted this photo to show the back end of barrel that contacts the Breach Face, and how it corresponds to the first part of breach face crack.

(Scrolling down over half way, and checking small photo insert at lower right where crack is first forming) (The insert photo is sideways. To right the photo in your mind you must look to the right side and note the protrusion that scoops the next cartridge from Magazine).

Or the 11 o'clock (fat part of triangle) on barrel corresponds with the 1 o'clock position on breach face. (As if putting two clocks face to face)

Where barrel hood hits breach face? and dry fire.

The more one digs the more interesting it gets. Nothing in this world is perfect.

At the below link, 5 or 6 pictures down, you see the cone shaped breach failure in a glock. This is important because it follows the shock wave pattern of what you expect to see from dry firing.

All of us that have ever shot glass with BB air rifles know the cone shaped fracture on the other side of the glass, from the shock wave.

But there is another perhaps larger issue, "in my opinion". In my last post I mentioned the smaller image in a photo where the crack began showing. And when I slowly lower the slide on my 40 cal glock that is where the barrel hood hits first.

When I remove the magazine, and shine a small LED flashlight up toward the breach, while releasing the slide slowly, that is where the barrel hood strikes first. And when I study the shiny line on breach face from the upper part of barrel hood hitting - it is brighter and more obvious at that point.

Keeping in mind that it first hit's the breach face at a slight dip angle then slides up into final lockup. In other words one would expect it to hit on the top edge of the barrel hood first. Now I note that it is one corner of the top edge.

(Disclamer - I have been wrong before and will be wrong again. And these handguns have been stress tested with excessive loads and allegedly millions of rounds fired. I am not worried about any of my handguns failing when shooting standard factory loads).

Anyway, at this time I will eventually dry fire snap caps, and will not let the slide slam closed when empty. I would like to file down the point/part of the barrel hood that contacts the breach face first, but I do not know enough about barrel hardness and such.

I have contemplated closing the slide with a small piece of carbon paper over the end of the barrel hood? Contemplated smashing a small piece of aluminum foil between barrel hood and breach face? (to examine)

All that I know for sure is that I have one more thing to look at when buying a new pistol.
