SELF COCKING 329PD.

[joebuck]

Hello, Have a 329PD that I got years ago that SELF-COCKED from single action firing yesterday with 180Gr PMC 44 mag ammo. This is the second time it has done this. Has this happened to anyone else? I am not a newbie to Scandium/Ti guns and shoot the 12oz .357 J frame and 17.5oz L frame guns with full power .357 a bunch.

Gun was held in a modified weaver stance when I fired.

The first time it did this was years ago with IMI(Hansen) 180 Gr 44 mags. They were HOT rounds. That time it cocked itself and the safety lock was activated also. Crazy. Gun has stock springs.

I just don't see how my thumb or any other part of my hands could have cocked it on recoil. I will need to do a Slow-Mo video record next time I take it out.

Just wondering if this has happened to anyone else with the 329PD. Thank you.

Found this link on the forum. Great info from Jaymore helping explain. Crazy.

It's from inertia. Another example of inertia are guys who are able to rack and cock a 1911 by pulling the whole gun back hard, then quickly thrusting in forward. I was never able to do it, but I've seen a few videos of it being done. I'm 99% sure the same type of force is causing your revolver to cock itself.

Tom S, I have seen a 1911 cocked that way, but, it had a very light recoil spring in it. Several of the IPSC master class shooters used to flip them that way, but I haven't seen it done for some time now.

I have heard/read of something similar happening with a 500 mag, only the gun not only cocked itself but double fired. I believe a woman was doing the shooting........

Sorry that I'm responding so late - I just saw this.
Yes, I've experienced this.
A year or two after they came out, I rented one at the Scottsdale range and purchased a box of 240gr. loads.
I fired 3-4 cylinder's worth.
I also had 2 occurrences of the gun self-cocking on recoil. I was firing double action at the time. REALLY didn't like that. I returned the gun to the clerk and told him about the issue. Argued with him and walked out.
I STILL have the remaining rounds somewhere.
I'd sold my personal .44s prior to testing the gun.
