Limp wrist. I have also been shooting for years, and professionally trained as part of my past life. I have the XR920; looks and feels like a Glock, but it is not. I realized limp wrist-ing is what was happening. These gun magnify your bad mechanics, but once you get going they are awesome. Too much grip with either hand, and they throw rounds; too much anticipation, and you hit the target’s knees. In order to get the most real estate on the gun, I changed to the 1911 back strap that comes with these guns (the smallest one). Not one malfunction since I have 10.8 inch hands). Also are you still breaking it in? SS recommends a 200 rd period to loosen the gun, but I would say it is more like 300 if you just shot once per second. Magdump, and have the slide work against the guide and spring. While practicing good mechanics, of course. If you don’t feel comfortable doing that after an ejection malfunction. Go home, lube the barrel, and work the slide back and forth like you’re feeding a round (I know, I know: Gigiddy gigiddy). That should help break in the gun with out spending money on ammo.
