I am sure that,18DAI was instrumental in my acquisition of a 4513,457,CS45 and my 4506. Several others on this forum fanned the 3rd gen flames as well and I do love them all even the 9's and 40's. Please don't hold it against me but due to rebate I purchased a Shield .45 about a month ago.It is also a nice EDC. I have several more S&W pistols and revolvers, but not a single Glock.
