I have an older BHP and it's got a good trigger and I've added an inexpensive after-market safety lever (still small, but larger than the original T-series safety). This safety on this slightly upgraded BHP is much easier to use (i.e., access) than the safeties on the SIGs. The only thing done to the BHP was to remove the mag safety and polish things up a bit.
I had a P-210-6 for several years, but financial needs led to its sale (along with a S&W 52-2). I'd like to get another P-210, maybe a Legend, some day, but other guns keep calling my name. The P210 was a superb SA gun.
I've had two other SIG SAO guns, as well. A
P-226 X-Five "Competition" in .40, and currently, a
SIG P220 Super Match. I never could shoot the .40 X-Five well,
but others could -- so it was me, not the gun that was the problem. It also wasn't the trigger. The X-Five SAO Competiton trigger was fine. Sig also offers user-tuneable triggers in other models. My problems were with the slide stop and safety lever, which I found more awkward to use than other SA guns. They were both was stiffer than I liked (and I'm sure that COULD have been made better), and not ideally placed. The P-220 Super Match has a very good trigger, but using its slide release and safety is awkward for me, too -- it seems to be basically the same design as those on the P226 X-Five.
Sending the X-Five to Gray Guns would have been the next step for X-Five, but I wasn't sure that gun and I a good match. (I have a P228 with GG enhancements and can only say Gray Guns does outstanding work!) I ended up trading the X-Five for two guns and cash (well-tuned and set up for competition to a guy who wanted a second X-five in .40), so I feel I did well in that exchange. (He probably feels the same.
)
These SIGs, unlike the P-210, weren't conceived as SA guns, so I suspect SIG has had to build in "adaptations" that may not be ideal. SIG makes great guns, but I'm not sure that their SA versions based on the P-series DA/SA guns are their best offerings. Many others seem happy with them, however.
