Knight still sells the 175gr RedHot and Barnes still sells the 195gr. Ive shot both and they both shot great for me. I still shoot the 195gr in my smokeless 45.

Knight now offers a 150gr too. All are made by Barnes. Personally i would waste my time with the 150gr unless you are very recoil sensitive. Even then you can buy the Barnes 40cal 155gr TAC XP pistol bullets cheaper.
