I teach a tactical class to civilan ccw holders, I have never seen a Ruger P model that has not jamed up when condtions are just not right for the gun, Every Ruger P model has had mulitble jams durring the course, Hope this helps,
P.S I am not running anyones gun down and do not wish to get is a Pissin match with anyone that owns one, Just passing along what I have seen with my own eyes.
LE agencies don't use Ruger pistols, by and large, because most agencies have moved to striker fired or DAO pistols. Until recently (SR9), Ruger didn't offer a good striker fired or DAO pistol like a Glock, M&P or the Sig DAK/HK LEM pistols. There were some limited DAO metal frame Rugers, but polymer is the overwhelming choice of agencies today.
There is nothing wrong with certain Ruger P series pistols for defense or general use. Only the P345 has had some problems with the ill-designed magazine disconnect. P95 9mm pistols in particular have a very good reputation for reliability.
I'm not sure what the shooter's stress level has to do with anything, regarding pistol reliability. Either they function or they don't, no matter whether the shooter is chilled out at the range or puckered up with bullets whizzing by his head. If shooters are accidentally hitting the safety during malfunction drills, that's a weakness of DA/SA pistols in general, not just Rugers. A good self-defense pistol will have a minimum of potential failure points.
The only DA/SA pistols that I care for are "decock only" models, and Ruger makes these. I used to have a P94DC in .40, and never had a problem out of it with several hundred rounds fired. Foolishly sold it, but I'm keeping my eye out for another. They are a bit heavy, but reasonable in price and make a good home defense weapon. Rugers actually have a good reputation for being solidly built and reliable, despite not being the prettiest girls at the dance.
By the way, the Federal Bureau of Prisons issues the Ruger P95 9mm.
If you think for one minite that there is no diferance between a fight for your life and poking holes in paper at the range you are living in an unreal world, I do not meen this as an attack against you, but there is a world of diff, poking holes in paper at the range you have the chance to get a perfict grip, stance, site alignment site picture, In a fight for your life you are trying not to get holes punched in you, You cant dictate when and where it will happen, the bad guy does, and he will attack when things look the best for him, not you, Your heart will be beating above 200 beats a minite, Minor motor fuction will no longer work for you, you will not have the perfict grip, stance, shooting postion, If you have not trained you will not react in a manor in wich you think you will! at 200 beats a min the only part of your brain that is fuctioning is the amegliea it only knows three things fight, flight, or freeze. What happens if you take a hit in your dominant hand? and have to respond with a shot from your offhand and have never shot a gun with it before are things going to be the same, I think not, It is not a perfect world and you need to train for an imperfect fight! again I am not attacking anyones gun as for me and mine I will carry a true combat gun, as you stated " A good self-defense pistol will have a minimum of potential failure points. " H&K, Sig, Glock, does that for me and have been battle tested. Gary
Hmm.., that's like the exact opposite of what I've heard (there are two Ruger forums on the Internet), and what I've experienced (owned P89 and P95 twice, owned P944 and P97 once. Still have a P89). Rugers are not known for accuracy...They have a name of "built like a tank". Heavy but solid, lacks a bit of refinement, makes up by overbuilt reliability and longevity...
