Words from the author: Please field strip your pistol often (every 100-200 rounds) to look for the initial crack before it's too late. The crack could be drilled. Or if you're the original owner, send it in for a warranty exchange. Look for cracks on the slide, hammer, and frame.
Please wear your safety goggles. The grip or the safety switch may come at you during a catastrophic failure. Other items that may come at you are:
A broken hammer,
brass shrapnel from a case blow-out
recoil spring during a field strip or
flying objects from your target area.
When there are no eye protection present, shoot horizontal (the practical, standard way) at eye level and squint then anticipate any problems by being aware of anything out of the ordinary.
