I have a 92SB and had a 92FS and they both have a really nice single action trigger. The reset is very short and the pull is light and crisp. I prefer the SA to a Glock, Sig and most DA/SA pistols. Now the DA trigger ion Beretta's is heavy, long and inconsistant , definately one of the worst I have shot.
I also found that they need to be kept clean to maintain a good trigger which involves a complete stripping every 1K rounds or so. Anyone that has disassembled a Beretta knows its a bit of a pain for regular maintenance. If you want to improve a Beretta trigger a G model main-springmakes a huge difference in the DA/SA models.
