My agency uses Ruger DAO P89, 93's and 95's as well as a couple different Beretta's. The key to shooting them accurate at range (20-25 yrds) is stage the trigger just like they did back in the DA revolver days. They can be shot as fast and well as a Glock it's all in prior programming and if someone wants to learn that particular trigger. Without trying to get myself in trouble here just an observation with 28 years of Governmant sevrice and most of that as an instructor starting out on wheelguns. Most of the shooters starting today are better served by a glock. They don't want to, can't or don't have the attention span to learn the DAO trigger. Glocks and M&P's and the like are great guns and not saying that just there isn't much to learning on them.
The difference between an instructor and a real instructor is your a real instructor if you can teach/instruct a novice and make them a marksman with a DAO. LOL
