Mine is a bit of an oddball, I bought it way back when they had slide cracking issues on the "wonderfinish" (plain DA/SA) guns on the .45/ 10mm slides. I bought it knowing that and when it cracked out, sent it in for the free "upgrade" in which they just tossed on an older style match slide and barrel which was thicker in the slide (wonderfinish guns had the slides kind of machined down super thin, they don't do it anymore). It was perfectly ok minus that known problem.
After getting it back with the new slide? I kicked myself in the ass HARD for not buying either the 9mm or 10mm Match Elite (SA only, really nice trigger for the price). Even so, the think as is is stupid accurate, runs reliably, and super hard to beat for the cost associated. 3-4" groups at 25 yards were almost easy, and at the time I wasn't even that great with handguns. With the match barrel and sights it definitely made it easier to show off.
Glock 10's are great if you're going to shoot a ton of hot 10mm, I've seen them take CRAZY abuse and my gut says I would trust them more for handloading really high pressure stuff. But the Witness guns especially the E. Match level and higher are factory competition guns and shoot like it. The factory recoil springs on them are on the light side, mine wore out pretty quick. Replaced with IIRC a wolff 22# and it's been great for factory ammo, and the occasional full speed stuff. I'd probably go a tad higher if all I was shooting was big boy ammo.
Don't have any experiance with thier polymer versions, but I've sold many when I worked at a range and no one ever had issues.
