I think after a 100 rounds or so my trigger got a little smoother and the gun was smoother/easier to rack. But it has worked without issue from the word go.
A critic could argue that I just got use to the trigger and it didn't change just my perception of it, they might be right...
I use 115...
Looks like lots of rabbit holes around here to run down...
As far as YOUR question;
My EDC is a 9mm shield. I feel like it is the biggest gun I can CC everyday. Fits my hand pretty well.
I like the 9mm because I can shoot it better than a 45.
Perhaps because 9mm is cheaper and I shoot it...
My shield has a thumb safety. Its my EDC, I like it that way.
For me operating the safety is as automatic as pulling the trigger.
If I was buying new and was unsure if I wanted it, I would buy with. You can always choose to not use it.
