I have a Glock 22, 23 and 27. Got them in the mid '90s. At that time the articles I read said the Winchester 155 grain Silvertip had a 96% one shot stop rating. Had about 500 ft. lbs. of energy. I startedusing them exclusively and still do. Kinda hard to find, but I bought several boxes and feel ready for anything.

My duty weapon is loaded with 165 grain Federal HST's and my Sig 239 is loaded with 165 grain Federal Tacticals. IMHO, Federal is THE premier ammunition manufacturer. I've had the fewest issues with rounds while shooting their stuff.
