Finally took my P220ST out! Gave it a good cleaning last night after finally picking it up, and took it to the range today. Man the gun was dirty coming from the factory. I know they test the guns at Sigarms for QA, and the inspectors QA signature was attached to it, so I had to clean it, but no problem. It gave us time to bond, lol! The dirt was much more noticable due to the silver stainless finish. The slide was very smooth as it glides against the frames rails. Very very smooth if i say so myself. Cleaned it down with MPro7 and then lubed it well with Militec and CLP. Shot 300 rounds without a single jam. And the extra weight on this ST is very noticable compared to my blued P220. About 12 ounces heavier to be exact. But very well balanced, and has a good hold and feel to my hand. I have to say that this P220ST is much more accurate than my blued P220. My groupings were much better, esp at longer distances up to 50 feet more or less. And not to be surprised, but I actually was able to shoot the gun off pretty well with one hand. At about 30 feet, I was getting all shots at a 2-3 inch grouping precisely and consistently. The recoil is still good like all P220's and all .45's, but the recoil is a bit more straight back instead of "muzzle up" and a bit more dampened. The front of the barrel or muzzle did not recoil as much due to the extra heft. I have to admit that the weight took a bit of getting used to, but after a few rounds, it all fades out and you get really used to it and enjoy the shots. Very very smooth, very very accurate, and very very nice! I must say that this is the best big bore handgun I have ever shot and held. This is one sweet shooting machine!!!
