My 2 cents: the magazine safety doesn’t really matter to me. I find it slightly annoying because it requires me to put an empty mag in for dry fire practice. I have 4 S&W DA/SA pistols. I haven’t removed the mag disconnect on any of them. If I bought one with the mag disconnect already removed, I wouldn’t change it as long as everything worked fine. This feature is not important enough for me to remove the rear sight either way.

TL;DR - Pistol is fine. Do not !@#$
