The stainless slide makes it a little top heavy (more noticeable when empty mag), however I love both my standard 229 and 229ST in 40/357Sig, there is something to be said about a .40 that I can shoot as accurately with as any 9mm including my 228. I practice often with my 229s and balance has never been an issue for me, in fact I would say that the extra slide weight is what helps contribute to its easy handling/accuracy with hotter rounds such as the .40/357Sig. I love my 228, but if I had to choose one then personally I would stick with my 229 (also my daily carry). You definitely need to shoot one for yourself before forming an opinion as to whether you’d like it or not, for me it was my answer to the perfect handgun, 12+1 of .40 S&W in an incredibly accurate firearm that was specifically designed for that caliber.
