I am not an authority nor am I a member of an elite military unit or LEO agency. I do like guns and have owned Sigs, Berettas and Glocks as well as numerous other makes of lesser stature. The Ruger P-Series does not have the refinements found with the high-dollar Euroweapons or Custom Yankee 1911's. They are a good value for the money and are built like Sherman Tanks.
I previously owned a P90 that was well-balanced, fairly accurate and totally reliable. I was not in love with the green anodized frame but it grows on you.
I currently own the polymer-framed P97 chambered in the venerable .45ACP caliber and have noticed several enhancements. To begin with, it is thinner than its predecessors. The slide has serrations which aid in its manipulation and it bears a more streamlined appearance in this layman's humble opinion. The P97 has more slide to frame contact area which may account for my consistent 10-yard, five-shot groups of .75" The lock-up system is new resulting in a felt recoil that is suprisingly mild for a polymer-framed, big bore semi-auto.
The SS investment-cast slide will rust if not taken care of. I witnessed this first-hand with the P90. However, being the type of guy who will tinker, I have come up with a solution for this. I take Breakfree LP, not CLP and thoroughly coat the slide in it and allow it to soak into the surface area for two to three hours. Then after that, a cursory wipe-down every quarter and you are good to go if you are not a frequent shooter. If you shoot alot and clean your weapon after every trip, the problem is takne care of. Always avoid long-term sotrage in a leather holster as the leather will retain moisture leading to corrosion on a Ruger P-series. The trigger will be stout for the first thousand rounds but then it will smooth out. The tendency for the SA Pull to have an excessive amount of take-up has been improved with the P97. To me, Rugers have always had one of the smoothest DA pulls in the industry.
A Ruger P-Series will shoot ANY, ANY factory loaded ammo and it says so in the manual. Standard Pressure, +P,+P+ or whatever. For the money and durability, they can't be beaten IMMHO.
