Went to a gun shop last night and looked at a Tarus PT140, P100, and a Ruger P95, P89. All are double action triggers for every shot. I only looked at these due to wanting the DAO for concealed carry, not sport. All triggers pulled like my S&W 586 double action revolver. It'll be bad enough being forced to pull a gun in Michigan. An accidental discharge after pulling it would be VERY bad.
The PT140 is small, easy to carry, has a well placed safety. I liked it till I dry fired it. I personally don't like the trigger. Pulling it back slowly for a controlled fire (like a double action revolver) the trigger has a small amount of binding. I could hear the trigger mechanism as I pulled it back. Sounds like plastic squeaking together (like a squeak in an old car's dashboard). This caused a slight jerking motion of the trigger as it was pulled slowly. Other posts decribed it as "spongy". The trigger guard is also too small for my liking. My finger rubbed the botton of the guard the whole time the trigger was pulled. I pop off a 100 rounds at a time while practicing. I can see the blister now.
The P100 was a different story. The trigger was smooth and consistant till just before it broke over. The gun as pretty good balance, but the barrel is a little longer than what I want for carrying.
The Ruger P89 - manual safety and P95 - manual safety are the same trigger. The P89 is a full size model, so I put it down. The P95 is 27 oz., with a shorter barrel. The safety wasn't as easy to release as the Tarus. But it can be left off if needed because it's the same as their dao model, but with a manual safety which disengages the trigger. The trigger pull was about the same as the P100. But was smooth and consistant all the way back. Pulling it slowly back, it was like butter. I'm thinking of getting the dao model which has the same trigger, but doesn't have a safety, so it would be the same as carrying a double action revolver. The price I got was $390 for the Stainless P95 or $410 for the Stainless P97 (.45 ACP). Their's also a $40 Ruger rebate going on till the end of the year.
