I am now excited to compete with my new Browning Hi Power. I have some questions regarding modifications:

1. I am going to remove the mag disconnect, but would like to improve the trigger beyond that if possible. I have noticed that C&S make a wide combat trigger and Garthwaite makes a competition trigger has anyone installed these in your Hi Power?
2. When I take the gun into a gunsmith for a trigger job what should I ask for as far as #trigger pull?
3. Has anyone replaced the thumb safety on the Hi Power? I noticed that C&S make a wide and extented version, and a ambi saftey. Would you recommend a ambi safety for IDPA?

I hope all of this is within the rules of play.

Thanks,

Kevin
