Great info gentlemen...tks. Any problems noticed with you G26 Gen4?. Just purchased mine and shot over 175 rds of white box 115 gr and Gold Dot 124gr with no problems. I love my first Glock but am highly disappointed with all the (reported FTE and BTF) problems with the Gen 4's.. Mine has the 30274 ejector and 018 RSA. I am thinking about replacing sights and have an extended Glock slide stop on the way. Any recommendations will be greatly appreciated.
