Update to this thread, I received the Cebo large safety and it worked great coupled with a set of LOK palm swell grips. Thanks again for all the suggestions.
Just a heads up if you order from Cebo and pay extra for the UPS shipping it only takes a few days to be delivered to the US once shipped, well worth the few extra $$. Also Cebo sells TSO 20 round magazines for $30 per so if you are already ordering it does not hurt to add a few extra magazines since its almost half the price when ordering from CZ
