I prefer the SIG P245 for a compact .45 though I do like the ergonomics of the Kahr. I would speculate that between the two guns you listed, the Glock will be running long after the Kahr is in a recycle bin somewhere.

Every Kahr I've seen in even moderate round count training exercises has gone down for the count. I expect that the Glock would outlast even my P245 though that gun has gone through several high round count classes without a burp or bobble.
