Re: High Power (Browning and clones) trigger
I have some twenty handguns and on almost all I have done some degree of trigger work. The Browning clone (CD) was easier than most but the magazine safety has to removed before the trigger assembly can be removed from the frame. I have all the right tools to do the work so it is no big deal for me. This gun was easy. A Ruger: I have not done any Ruger other than the Ruger MK II 22. For that I used a jig to reshape the trigger/sear surfaces. Today you can buy drop in trigger kits from people like Volquartsen. Still some of these handguns require tricky techniques to take them apart and put them back together. I have had to make assembly pins (short pins to hold parts together while being installed into frame) for some of these guns. Every gun is different. It takes mechanical skills and help from a manual, sometimes.
On this gun knocking out a single little pin moved the trigger from a heavy creepy lawyer safe trigger to an absolutely excellent trigger. Not all guns are anywhere near as easy!
I don't carry this gun or any other gun so liability is not a problem. Having a trigger than is light and crisp is most important for maximum enjoyment at the range. My defense gun for home is an un-molested Sig 225.
