Picked up a M&P Shield. May change the trigger.

I really like the Shield, but the trigger I'm iffy on. Maybe because I am used to a larger handgun and not a compact yet, but at times it seems stressful to shoot.I've only put about 150 rounds into it though. I'm thinking of putting the Apex trigger in it, but is changing the trigger of a conceal carry weapon recommended? Is it worth the $150? Thanks. via /r/CCW http://ift.tt/2rNwpvP
