Barrel Accessories

[Juggernaut]

I am looking to buy some barrel accessories for my Tec-9 and my Cobray M11/9. Will someone help me out with the thread sizes? Both pre-ban. My local dealer can only tell me "they're the big threads"(???). Thanks in advance.

the thread pitch for m11/9 is 3/4x10 which is pretty large considering most 9mm pistols are either 1/2x28 or 13.5x1 LH

Ok thanks. I have the factory thread protector for the Cobray and it almost fits my Tec so I was thinking they were close to the same size?
