Took my STI Spartan V .45 and Kimber Ultra Raptor out for a joy ride today. The Raptor is on its second treatment of 100% FrogLube and the STI was cleaned and treated with both Combat Wilson oil and grease. 50 rounds each and both flawless. The STI was it maiden range trip and the Raptor maybe up to 300 rounds total now. Target was at 15 yards. switching from and ultra to full size keep having to adjust my grip, but I was happy with the results. See for yourselves.
