From looking at the Glock slides they appear to be stamped. The low weight of the guns also seem to point to stamped slides when compared to other polymer guns with milled slides such as the USP. Does anyone have an official source that states that they are not stamped?

[Duncan Idaho]

I don't know if I am an "official source", or not, I only own one.:rolleyes:

My Glock 29 slide is milled. It doesn't exhibit symptoms of "low weight".

Quite frankly, I have no idea where you came up with the assumptions you have made about Glocks.

Perhaps you might want to go to a gun store, or a range, and actually handle/look at a Glock.

You can tell by looking if you know what to look for . But whether it's cast ,milled or stamped it doesn't really matter. What does matter is what material is used ,the heat treatment and the design. Stamped sheet metal only tells you the forming method - it could be low carbon steel, high strength alloy steel or even stainless steel.

My Glock 30's slide doesn't appear to be stamped either. Maybe you were looking at an airsoft or replica gun? :D

Maybe confusion with SIG, whose slides are made from heavy pressed steel with the breechblock inserted and pinned and other pieces electric brazed in place.

The stainless Sig slides are investment casted by Pine Tree Casting. Sigfans hate that when I tell 'em (but hey, I own a Sig too).

[Blueduck]

If I found out my Sigs slide was cast by Pine Tree Casting I'd just pitch it on the ground and walk off!

Might be true, but SIG isn't the only one using investment casted slides. I bet that Colt's 1991 are also casted. When a finish on a stainless slide looks too good to be true, it might just be. Look at a stainless slide on a Beretta and you will notice that there are more machine marks and chatter than on a SIG stainless slide. I know for sure that Beretta doesn't use casted slides.

The slide on my G22 appears to be a stamped shell with milled parts welded into it. The shell is stamped, machined and then assembled with the interior portions, they are welded in and then finish machined, that is what I see when I look at it anyway..

[mete]

Yes , Ruger's Pine Tree Castings makes stuff for other gunmakers. But many guns have been cast, Browning HP, many 1911 copies etc. Contrary to some of the advertizing hype ," modern space age technology" the method has been around for well over 500 years especially perfected by the Incas in south america.

[daniel (australia)]

cas'ting n, metallurgy: mixture of impurities, entrained slag, cracks, cold shuts and porosity, more or less held together by weld metal.:neener:

[Rob96]

Might be true, but SIG isn't the only one using investment casted slides. I bet that Colt's 1991 are also casted.


Wrong!!!!

Made from forged steel:

Slide, Frame, Barrel

[Rob96]

Investment cast on a Colt 1991A1

Thumb Safety, Grip Safety, Plunger Tube

Stamped steel:

Firing Pin Stop, Springs, Trigger Bow (alloy or steel finger pad)

Forgot to put in the forged parts, the slide stop is also forged.

Glock slides are milled on CNC machines from a single block of ordinance grade carbon steel.

[9x19]

None of my Glock's slides show any evidence of being stamped... but each shows clear evidence of machining, such as the extra cuts and disconnector groove.

FWIW

[Sean Smith]

Uh, no. :rolleyes:

This is absolutely correct and I have no idea how you could look at a Glock side and believe that it is stamped.

[bad_dad_brad]

tac17,

Right on. What can you say. To this day the myths and misunderstandings about the Glock still amaze me. I always love the story about being able to take a Glock through an airport metal detector - un-detected. Just try it, and the TSA will be on you like bees to honey, scum on a pond, and flys on ****.

Glocks - like Dr. Pepper - so misunderstood.

Gee whiz - stamped!
