So you may be able to find a a Canick 55 shark used but if not the Canick 55 is basically just a The CZ 75 knock off, or clone (however you want to phrase it) so if you are unable to locate a true replacement the CZ 75 will give all the same features and performance as the shark.
I did find a site that says "contact us for availability on the shark

The T100 I found on another sight that says " out of stock currently accepting back orderd" but no ETA on how long your wait could be
*** edit it won't let me link to this sight so look up imp@ct guns (use an A instead of @)****
There's a couple of starting points for ya hope this helps have a good one.

Due to the Panic buying and the fact that many manufacturers are either shut down or running at reduced capacity due to Covid 19 it makes it impossible to know when items will be back in stock
While I am sure that buds has them on order there is no way of knowing when it will be back in stock. I suggest that you use the notify me button. Buds will email you when they are back in stock This in no way obligates you to purchase the item. We are not buds employees we are volunteers that answer questions

Jeff, no more imports in the foreseeable future Sir. You may be able to find either large gun and accessory sites like (6)un (8)roker or Armslisy as discontinued and hard to find firearms and accessories show up for sale by private individuals and small shops. Just replace (6) & (8) with G & B.

Check the manufacturers web sights to see if they are current production. When is a question that is hard to answer.
