Chip McCormick easy fit 1911 sear

I just bought a Chip McCormick Easy fit 1911 sear Sunday at a swap meet.
So the guy who sold it to me said he installed one & took it to a Local Gun Smith who
said it was good to go. Gun smiths like Mechanics come in all flavors so who knows if he knows what he is talking about. This is why am asking for some knowledgeable answers.

So installing is easy but how do I safety check it? Is it just this sear or do all brand 1911 sears need a safety check? I have put a bunch of sears in the Ruger 10/22 & they all work fine. What is different about a 1911 sear?

I got it for $5.00 & do not need a sear unless it is somehow better than the ones in my Colts.
Just curious as how to safety check a new sear. You never know when you may need to replace one. Thanks in advance.

 

Thanks Bender all good tests to live by.
This should be a sticky post.

While safety checks are an important part of any work done on a firearm. As I said there is no drop in part that can be expected
to perform perfectly. So every job must be done right or take it to a competent Gun Smith!

So for the above question, I posted the answer I found & must be done right.

Every job has a right & a wrong way to get it done. I only understand the right way. That's why I have both my eyes & all ten fingers at age 66.
