Hi Op,
Others have already said this - my view would be get a G34 or a CZ shadow 2.
- Glock 34 - AKA plastic fantastic... cheap, easy to maintain, lots of "how to" video's, parts a plenty etc and you can always become a member of the GSSF and do the armorers course... good way to improve your learning. You mentioned you were not a fan of Glock triggers, I ended up putting in a Vanek custom trigger in mine (think it was the GM??) and swapped out the sights, still not a 1911 trigger but good enough for competition. I have put 1,000s of rounds through my G34 and never had an issue- its like a Toyota! Word of warning, once you add sights, trigger jobs etc, the price can get up there!!
- CZ Shadow 2 - I loved the SP-01 - better out the box than a Glock (just my opinion) but will blow your budget. If you can get the funds, based on the SP-01 it might be hard to beat. Whenever I shot my friends Shadows I was always envious. Shot really well and it felt like all the top production shooters at the time had shadows
- G17 - Honorable mention - seen plenty a A/B grade shooters do very well (much better than me!!) with a 17 and just a -2 disconnector (and swapping out the front sight as the factory one looks as big as a dinner plate once you shoot distance). The reason this gets an honorable mention is that when you add up the firearm, belt, holster, mag pouches, ear-pro, eyes, spare mags, range bag, staple gun etc etc, you will chew through your budget in no time and might be glad you have an extra 200usd in your pocket. Warning I started with a 17 then went to a 34, so this advice may not be the best - buy once cry once
In all honesty, I agree with the comments above, any of the striker fired pistols will do the job. Albeit 8 years ago, when I was shooting competition, the majority of production shooters at the time shot either a CZ or a Glock in 9mm. Not sure if this is still the case but others can comment if this has changed any. If it hasn't - it says a lot
My advice - Once Covid has subsided, if they carry the models I would go to an indoor range and shoot all of them back to back. choose which feels best in YOUR hand
Good luck
