I like Silvertips and Gold Dots, and have plenty of both in many calibers.
You may want to pass on the Critical Defense ammo, they had some issues with hard primers that caused failure to fire.
It was apparently limited to certain lot numbers.
I agree that in your initial testing the recommended STs and GDs are a good starting point, but don't limit you options, you never know when product will no longer be available. Just a short time ago finding Silvertips was all but impossible, my thought is there are many other very good carry choices available and the only way you will ever know if they work in your pup is to try them.
