AZRat, Looks like you got a good deal on the P95. There have been several variations of the P-95. DC is a decocker model ... probably the most desirable for a carry gun. It doesn't have a manual safety, just a lever to decock the hammer. The current model P-95 and has a manual safety that also functions as a decocker. The DAO model is double action only and has the long heavy trigger pull for each shot. All the models were available with both blue and stainless slides. Anything stainless will start with "K". Yours should be a KP95DC.
In my opinion $250 for any reliable, functioning gun is good.
Safety - Manual Safety
DC - Decock
DAO - Double Action Only
Here is what happens after you cycle the slide and put a round is in the chamber.
Manual Safety - Rotating the lever on the slide drops hammer safely, stays in "Safe" position. Gun cannot be fired until lever is manually place back into "Fire" position and trigger is squeezed. First trigger squeeze cocks the hammer & fires, giving you 2 actions in 1 pull, or Double Action. Slide cycles, ejects empty shell casing and cocks hammer. Next trigger squeeze only fires, 1 action 1 pull, Single Action. This is also known as DA/SA Double Action/Single Action or TDA Traditional Double Action
Decock - Similar to Manual Safety where rotating the lever on the slide drops the hammer safely, but the lever then springs back and returns to "Fire" position when released. Firing is then DA/SA action as described above. No need to rotate "safety" lever before firing.
DAO - There is no lever on the slide. Trigger squeeze cocks the hammer & fires, giving you 2 actions in 1 pull, or Double Action. Slide cycles, ejects empty shell casing but does not cock the hammer. Next trigger squeeze cocks and fires. Each trigger squeeze is only Double Action, hence Double Action Only.
Congrats on your P95DC purchase! $250 (in good used condition) is a fair price. I've put over 1500 rounds in mine and have found it to be a great firearm (You will eventually get comfortable with the decocker feature .... but the first few times you drop the hammer with one in the chamber, it does feel a little odd)
