Cisa?

[Pickitup]

Hi there!
There's a lock that i'm tryng to open since a month....
something like security pins or other...
Any suggestion?
Here is the lock

Note that behind the lock there's a numer "210/50"...
is that anything important for the picking?
Thank you all!!!!!!

Cisa can be a difficult pick and can be very difficult even with the pick-gun due to the security pins and the tight keyways.

The 210/50 is the product number from the standard Cisa range.
