I had a gen 1 M&P 40 full size. About 2 or 3 times a box, I would get a dead trigger. The sear spring was not strong enough to hold, and under recoil, the sear would bounce out of place. I called smith, and they knew exactly what the problem was, and fixed it for free. My only concern is, how many of those gen 1s are floating around that will experience “sear bounce”, and the prior owner never shot it enough to experience it. Probably not a major issue, but I thought I would mention it.
Oh, a factory 9mm barrel will drop right in a 40 and run pretty well. So cheap practice ammo. I got 9mm barrel for $85 back when I had the gen1 40.
I also found the gen 1 trigger to be mush, with a mush reset. Traded it off. Not a bad pistol, but not my favorite.
Then a year or so ago, I shot a 2.0. Miles better trigger, miles better grip texture, so I grabbed one in 9mm. The 2.0 cost more, but I like it better. By the time you find a 1.0 and drop an apex trigger in, you are in the price range of a new 2.0....

I'll admit that I picked up few 40 cal 229's when they were cheap. I remember people paying in the $800 - $900 range for these while I was in the police academy. I couldn't pass on them at 350ish.
Whatever you do buy used.
When things calm down people will dump their forties again.
A year ago local gun shops wouldn't even take a 40 in trade.
One other nice thing about the P229/P226 in 40 is that if you want to change to 357Sig, all you need is a barrel for $123.00 . . . bought some of the CDNN CPO's myself before thing went insane . . . they we "Like new CPO" as described fkr $499.00 . . . gone now though, but a good source.
