I recently acquired a used Ruger P-345 .45 ACP semi-auto pistol that was very dirty and missing magazines. As the slide and rail showed no adverse wear and it was the de-cock model without the problematic external safety, I put money down and began the California mandated 10-day wait.
After taking delivery, first step was a complete and detailed cleaning.
After field stripping the pistol, the stainless upper parts (slide, barrel rod and spring) received a deep cleaning in my Lyman Ultrasonic Cleaner; two cycles of eight minutes each.The poly frame received a liberal dousing with SimpleGreen (I prefer the purple commercial). After cleaning, I used distilled water to rinse the poly frame to remove the SimpleGreen followed by drying with compressed air. Next, I applied a liberal spray with Kano Sili Kroil. I set that aside while I worked on barrel and slide.
The barrel received a soaking in Hoppe’s #9 and bronze brush to clean the inside. Stubborn deposits on the feed ramp and around the chamber opening received attention from solvent applied by nylon brush. A couple solvent-soaked patches through the barrel were required before a final wipe with a dry patch and light coating of MilTec-1 oil.
Last on the list was the slide. The slide went through two more ultrasonic cycles with manually moving the ejector and Loaded Cartridge Indicator between cycles before carbon residue quit appearing. A rinse in distiller water, compressed air dry, soak in Hoppes #9, followed liberal spray of Rem gun oil and it was clean.
I considered stripping down and completely cleaning the the ejector and firing pin channels. But, after the extended ultrasonic, followed by wipe-down with Hoppe’s #9 and Rem gun oil, carbon residue quit surfacing.
After a final blow out with compressed air, I did a wipe down and reassembled the gun, added oil to a couple judicious points, began working the slide and wiping off excess oil.
What was interesting, I loaded a magazine and began working the action. The first two magazine cycles I had some failure to load. After cycling about 100 rounds, I had no feed or ejection issues.
Next was a trip to the range to see if there were any issues with the neglected P-345.
In double-action, there is a long trigger pull. However, once a round is racked and hammer cocked, trigger action is clean and crisp. The grip and trigger feel was a good fit for my hand. In other words, the grip natural and comfortable in my hand.
I shot 64 rounds and was pleased with my groupings. Noted, my first 8 round group was within an 8 inch diameter. Subsequent rounds brought the grouping diameter within a 6 inch diameter based on a 10 yard target distance.
As a comparison, I shot with four pistols that trip. With the P-345, my groupings were consistent center and high. With my Para Commander Elite and Rugar P-89, my groupings were consistent high and right. The outlier was my Ruger SR9C. My grouping were more than 10 inches in diameter and low left.
I am still working with the SR9C and am considering the XS sights to replace the stock three dot sights. But, that is another story.
Overall, I am very pleased with the feel and response of the P-345. It is a keeper.
