Since the LWD slide is solid top, ie: heavy, I wanted to bring the weight down to what a factory G35 weighs. But I also wanted to add some weight to the nose of the gun for recoil reduction.
I went with the G24 slide for a longer sight radius and to gain a small bit of velocity as I intend to use 170gr bullets.
eta: I have spoken to a few GM, M in USPSA Limited division, as well as gunsmiths who build Limited guns, they all like the slides to be around the 11-12oz range. Granted, that is for STI/SVI type guns, but the principle is still sound for any gun that will be shooting the loads that make major PF in our sport.
And lets face it, I wanted something a little different and I prefer to stay with the Glock platform as that is what I carry daily. I could have easily had an STI/SVI 2011 gun built by anyone of the big name gunsmiths, hell, I have one of the best here locally. Hell he is the one that did the machine work on the slide.
