Marcus, I received my order a few weeks back and decided the pistol I was going to try these three products on was my older Series 70 Colt 1911. First thing I did was completely clean the pistol with the Modern Spartan Systems Carbon Destroyer and it did a fantastic job. The only place I used the Modern Spartan Systems Accuracy Oil was on the hammer pivot and the inside of the barrel, everything else got the Accuracy Grease. I knew I would not get to the range for a few days, so for the barrel I applied the oil then heated it with a hair dryer for about 20 minutes, let it cool and applied again. I did this for 5 applications. Once I got to the range I applied the oil after every magazine for five magazines. I can tell a difference in the groupings from every distance I fired the pistol and the more I used it, the tighter the groupings got. But, the main thing I noticed is the overall smoothness of the pistol. The way the slide racks, the way it recycles, and the accuracy. I am very pleased with your product and plan to use it on all of my pistols and revolvers. Thanks for the excellent product.
