My latest and greatest .45acp is a used Sig P220 SSS, stainless frame, no beavertail, fancy aluminum grips, night sights, trigger job?
$750 on Gunbroker. Sold the grips for $75, selling the night sights for $50, gets my price down to $625. Helluva pistol for that price.
The P220 has my favorite grip, really locks in to my hand better than anything else, slim like a 1911, but a better shape for me.
Accuracy has been outstanding, as good as my old USP .45, which would be another .45acp I highly recommend.
The Glock 21 is a good pistol, just harder to wring accuracy out of it. Mine shot like a match pistol with Federal Eagle 230 ball, but not so good with my plated handloads, which the Sig and the USP shoot to match accuracy.
