I've searched (x d s is too short to register), and I've read the thread on the XD "hate." I find the rental range reports of failures disturbing. The grip safety locking the slide is a huge problem.
However, the X D S design fixes that second flaw. I find the grip safety quite okay and helpful for an occasion when it could be handy to drop the pistol in a pocket.
I have only 400 rds through mine, so I can't say much about reliability, except that mine's perfect so far.
I also shoot it incredibly well (9mm version), much better than M&P and almost as well as my G19.
I stayed away from Kahr due to reliability reports.
Has anyone here spent enough time with one to know if this newer design has improved the XD series significantly? Thanks.
