And it seems I'm not the only one.
I like nice, consistant trigger pulls, never had anything but trouble with da/sa pulls. Either there's a silky smooth, perfect double action pull, and then the single action pulls have a mile of slack and only break in the last half of a millimeter of pull, or the double action pull is unbelievably terrible, but single action is nice and clean.
Only gun I've ever used that played nice with both was a rented .357 magnum revolver. I've used significantly more DA/SA guns than one, so that's not a very good record.
Basically, if you use something DA/SA, practice for it. Me? I'll stick with my Glock Brand Glock Safe Action Trigger.
