I've always been a Glock fan. Fate has taken away my beloved G21 in a millisecond. Kaboomed it a couple of weeks ago due to a double charge. **** happens when you get too trustworthy and let your guard down. So to get to the point I just discovered inadvertently that the Sigs are fine pistols. I picked up a sig 229r nitron and like the feel and ergonomics of it. I've yet to shoot it. Just wondering if anyone here experienced any issues with different ammo types? For example problems with cast SWC or others. Thanks in advance to any useful replies.
