I was informed by the folks at Sevigny Performance the sights for the G17 and G19 will work on the G43. Once they developed sights for the G43 the ones for the G17 and G19 were the same. This is in regards to the Warren Tactical and Sevigny sights.
This is interesting. I have not had any issues with the AE 147gr ammo in my G17 and G34 with 13# recoil springs or a G19 that is bone stock. I just ordered more of this ammo so I will keep my eye on it. Thanks.
