See old LSP there.... he does this **** for a living.

Take his word for it.

Actually, I do it for gun & bullet money.

And here we were thinking you just did it for the lulz....

I dont know...

determining guilt solely through something that is machined the exact same way through the same exact process on a production line is a scary thought...

The point is, it's NOT machined the "exact same way", not at the microscopic level.

While there is machining in the aero space industry that can ALMOST be completely identical, for firearms and tools, not even close. Interchangeable? Yes. EXACT same? No. Totally different standards.

Just saying.

That is why you need to have a "throw down" barrel. Good prep leads to success (write that down).

There are "other" bar codes on that gun if you care enough to find them

IIRC there should also be one in the back side of the magwell on the internal side of the frame, all the DOTS should be the same as a "match", this allows to identify the frame even after the serial number up front has been removed or scratched off.

Pretty cool.

And you'll still get caught...

And this is why you shouldn't engage in illegal activities.

Serious question time. And before anyone laughs- you know damn well you've heard at least one person say this in one form or another...



How advanced (without going into any intimate details, of course) is this type of technology when it comes to scatterguns- or is it even possible to somehow make a similar connection with a smoothbore (even in the case of say....a slug fired from a non-slug barrel)?

I consider myself a gun guy and understand all the basics (more or less)- but I wouldn't mind hearing once & for all from someone in the know to at least dismiss some of the scuttlebutt regarding this.....

I seem to remember this odd-looking dot matrix arrangement visible within the frame on some Gen 3 pistols that I had detail-stripped to clean/service.

.

Yep, seen a few there myself-- I'm assuming on the very newest iterations of that Generation.

You M&P owners probably have one on your frame as well, just forward of the locking block IIRC. They were only made without them for a couple of years, so it's much more likely. You've also got a series of dots on your slide, where the barrel hood contacts the inner surface when the gun is fully cycled. They exist to identify which machine turned out the slide so that if there's any problem, they can track it back to the equipment.

Let's just say, I wouldn't use one that has choke tubes...

With projectiles, be it a bullet or shot cup, its always hit-or-miss on making a positive ID. Lots of factors in play.

But there are other factors which are pretty much dead-bang... and I'll leave it at that.

I got ya....Thanks!
