    This is the best Glock animation I've seen.

    Thanks for posting it.

    Best regards,

    Is it sticky worthy? I was unsure.

    Very informative. Thank you for this! Can I show this to my co-workers and my firearms instructor?

    Best 3D animation of a Glock I have seen until now.
    Great, thank you.

    Excellent video.

    This LWD video is the most complete I've seen to date.

    Thanks for posting.

    Best regards,

    Both are good lone wolf is more accurate in terms of barrel locking. Other video said video locks in slide nothing in slide to lock to. Lugs on bottom of barrel lock to lug and take down lever.

    Well... to 'clarify' the slide-to-frame and barrel-to-slide 'lock ups', let's examine them in a bit more detail.

    In battery, the RSA forces the slide assembly forward in the frame, binding the front barrel locking lug (arrow 1) against the slide lock (arrow 2), the barrel muzzle against the bottom of the front cutout of the slide (arrow 3), and the rear of the barrel hood 'up and back' against the slide above the breech face (arrow 4). The upward movement of the barrel hood is 'stopped' when the front 'step' of the barrel hood (arrow 7a, post #18) contacts the underside of the slide (arrow 7, post #18).

    Barrel locking lugs in slide - arrow 1.jpg Slide lock and locking block - arrow 2.jpg
    Slide assembly nose - arrow 3.jpg Barrel hood in slide - arrow 4.jpg

    At this point, typically, with the exception of precision 'handcrafted' custom pistols, the rear locking lug (arrow 5) typically 'floats' a few thousandths of an inch above the locking block (arrow 6). (This may be confirmed by pushing down on the barrel hood tab when the slide is in battery. With 'drop-in' barrels, the barrel hood typically 'depresses' about 0.005".)

    When a cartridge is discharged, the primer pressure forces the primer cup rearward and the barrel forward, binding (locking) the front of the barrel hood against the forward edge of the ejection port in the slide (arrow 7). As the propellant burns, since the chamber is sealed by the case and the barrel is sealed by the bullet, the chamber/barrel pressure forces the case rearward (reseating the primer cup) and continues to force the barrel forward, maintaining the slide-barrel 'lock' until the bullet exits the muzzle.

    When the bullet exits the muzzle (the slide assembly has moved rearward about 0.030"), the pressure drops, 'unlocking' the barrel from the slide, allowing the rear locking lug (arrow 5) to drop against the locking block (arrow 6). After the slide assembly moves rearward about 0.080", the rear barrel lug drops off the 'flat' of the locking block (arrow 6). Then, after the slide assembly moves rearward about 0.110", the rear of the front locking lug (arrow 8) engages the front ramp of the locking block (arrow 9), ensuring that the barrel properly 'drops and tilts' to provide the necessary clearance for the slide cycle.

    Barrel locking lugs in slide - arrow 8.jpg Slide lock and locking block - arrows 9 & 11.jpg

    When the RSA returns the slide to battery, the front of the rear locking lug (arrow 10) engages the rear ramp of the locking block (arrow 11) and 'lifts' the barrel hood 'up' into the slide. The RSA then pushes the front barrel locking lug into the slide lock, the barrel muzzle 'down' in the front cutout, the barrel hood 'step' against the underside of the slide, and the barrel hood tab 'up and back' against the slide above the breech face (refer to paragraph 2, above).

    Now the pistol is ready to discharge another cartridge.

    Hope this helps.

    Best regards,

    Bob

    I just noticed an omission in paragraph 2 of post #16.

    In battery, the upward movement of the barrel hood is 'stopped' when the front 'step' of the barrel hood (arrow 7a) contacts the underside of the slide (arrow 7).

    Hope this helps.

  19. PW may be going to run a few boxes through my comp guns and whatever is around. Drop me a message I can call you back. Late morning would be good for me. If not next time. Dave

    Dave do you really want everybody on the forum to see your contact number or do you want me to hide it from public view and send it to Jim
