I recently picked up a LH CZ 550 in 375 and intend to change it over to 458 Win mag (already have the barrel). It's quite a hefty rifle in 375 (9.5lbs bare weight) with stock dimensions that would please the Hulk. Having said that there seems to be more than enough timber in the right places to turn it into something a bit more handy but that will be a job for a pro and I want the metal work sorted first.

My questions are about the trigger and safety. I'm not sure what CZ were thinking when they fitted a set trigger on these large cals, but it seems to be an unnecessarily complicated option on such a rifle. Some seem to really like it and some don't. The trigger also sits quite a ways forward of the rear of the trigger guard. Should I persevere with the factory set trigger or swap it out for something simpler and that hopefully sits further to the rear of guard? Any other options, maybe from a local smith ?

There are a few 3 position safeties available for the RH version, but so far I have drawn a blank on one for the LH version. I know AHR have one but they will only fit it themselves and that's not feasible. Any ideas here ?

Any tips, comments or advice are welcome.
