Easy on the assumptions. I said it generally wasn't necessary ... I didn't say it was hard to figure out or I didn't know how to do it.
Function checks and changes in trigger pull will highlight wear areas.
Do you really detail strip all of your firearms every time you clean? If so, good on ya.
I don't usually have that sort of time and the weapons don't require it.
And have no manual safety and don't fit my hand and don't conceal well for me.
I have several 1911's (including Kimbers) and I shoot on average almost 1000 rounds per month.
Yeah, WWI, WWII, Korea, Vietnam, etc. was a cakewalk for sidearms I'm sure
Regardless of your views on handguns ... get something in a caliber that starts with "4," shoot it often, and learn to shoot it well.
