I have a Stingray that is a very nice shooting pistol. I've had it about 9 months and recently something bad has begun to happen. The slide release/takedown lever has started to back out while firing. This results in the slide locking up until the pin can get pushed back into place. So my question - is there anywhere to buy a replacement part? I have sent a request via the Canik web site (twice) with no reply.
