Great video- thanks for posting.
I'd had issues shooting my G43 when it was brand new. Practice fatigue caused limp wristing, which in turn caused FTF and FTE. I've now corrected my grip. Plus, I don't need to shoot 100 rounds per trip to the range with my G43, but rather just enough to stay current with it. I'll shoot my G17 mostly.
Interestingly, I've never had a limp wrist issue with my G17 or G19, probably because of the thicker grip (compared to the G43).
Excellent video and instruction. Have recently traded in my Kimber Pro-Carry II/SS 9mm for the new Glock 43. We've been getting our usual seasonally cold temperatures so I was on here to do what I call "homework" to improve my shooting. The G43 is definitely much easier for me to rack the slide compared to the Kimber and, it's a nearly a no-brainer to clean and oil when also comparing it to my former Kimber.
I really enjoyed this video! Several years ago (pre-internet) I purchased a Commander sized .45ACP. After several magazines of FTF and FTE I sold the gun and went back to a .44 mag revolver! I later discovered that it was ME and not the gun. Coming from a revolver shooting environment and not used to the semi-auto pistol I was limp wristing a steel frame weapon. I now have several Glocks and other brands and don't have the limp wristing issue. I do still transition from semi-auto pistol to revolver back and forth and do notice a slight grip modification need going to the revolver (DA or SA) but no longer have an issue with the semi-autos. Practice does work!
