I have a Bond Arms Ranger ll...
It was totally disassembled.. all wear points polished.. sear engagement checked.. hammer spring shorten 10%.. and lubricated with a special oil I use. This gun is the later version that has the wider hammer spur and improved trigger. The pistol now has a hammer that is about 40% easier to cock and the trigger pull is set at 3 3/4 pounds.. which is light for a pistol of this type!
The lubricant is a blend of synthetic oil and TS-70 moly grease. It's hard to lube a stainless firearm because stainless is prone to metal galling, the moly grease is a paste and contains 70% molybdenum disulfide.
The ammo I use after many rounds of testing is a hot .45 Colt and lighter bullet than normal. This gives better speed from the 4 1/4" barrel and better bullet expansion from the short barrel. Hornady Critical Defense has proven to be a good factory load and a few of my hand loads has performed well in my test too.
