Re: .45 full size can suggestions
Cans with booster devices can be disassembled to a point. My Ti-RANT 45 and Evo-9 both allow you to remove the booster device to clean it and also clean the blast chamber. This is a necessity, as the booster/blast chamber area will crud up and stop working before too long. Shooting the can wet will speed up the fouling process. Also, your chamber will get dirty on the host much quicker with the can and you may have FTF after a while.
Some people complain that they can't see the sights as the can blocks their sight picture. This never bothered me. My HK tactical has tall sights, and you can purchase tall aftermarket sights for just about any suitable host firearm. That said, I do not have tall sights on my Glocks or Berettas, and I can hit with them no problem with the can on.
Some people complain about my little G26 when I shoot it with the flush 10 round mags - there's no place to put their pinky. This does not bother me either. I don't shoot with my pinky. People can always find something to complain about.
