Tisas 1911 a1




Anybody had this problem?
I recently purchased this gun, seemed to shoot fine, after 250 rounds the barrel blows wide open splitting the slide. I was using standard Winchester ammo. Does anybody know hardness rating, materials used?

I've got one on order. You sure it wasn't a double charged load or maybe a squib.

Any pictures?

after looking at the pic of the barrel, I noticed that the way it split showed it to be almost too ductile. Before sending it back I would have the barrel and slide Rc tested to see where the hardness lies. The steel may not have been properly heat treated during the process.

Where did you purchase the pistol from? I bought one from Centerfiresystems.com for $350 but sold it to a buddy recently before I ever shot it.

What are the first three digits of your serial number?

Is there anything in the end of the barrel? I'm not expert but it looks like a squib.

Very interesting how the barrel split longitudinally, then completely separated circumfirentially. The photo of the longitudinal split shows a ductile fracture, do you have a photo of the circumfirential fracture surface?

Did the round before that one cycle the slide and load another round or did you have to clear a malfunction and manually chamber another round?

the gun was purchased from academy sporting, dont be misled,the longitudal line is actually where the gunsmith cut it for ease of disassembly. last four s/n digits 2809.there was no rounds in the barrel.,

The fact that there was no obstruction after the blow-up doesn't mean much. It probably would have been pushed from the barrel by the same pressure spike that blew it.

The reason I asked about how the gun acted JUST BEFORE the blow-up is that is when you would have noticed something different.

A squib round usually won't have enough power to cycle the slide for the same reason it doesn't have enough power to push the bullet out of the barrel.

Most squib blow-ups in autoloaders occur right after a deliberate TRB by the shooter.

also, the slide failed in the typical fashion when there is a stress riser from a sharp direction change in the metal, hence where the slide transitions to the lower section that encapsulates the guide rod cap. Very poor heat treatment all the way around. Even my AMT pos did not do anything like that when it failed.

twould imagine here was no noticable differance in the round before the explosion , ejection extraction was all normal.when it blew the sou nd was quiet noticeablly muffled. I would imagine it was from the gas exiting through the slides interior.

Probably a squib then and like the other poster said it simply pushed it out when everything blew. Bad any way you look at it and I'm glad you are okay.
