Thank you all for your kind input. It is an easy thing to reduce the drop at heel; I can always make it a bit deeper if I don't care for it. I am leaning to keeping the comb drop at 1 1/4". This too is easy to increase if needed. Most of the guns I find most comfortable have a drop at comb of 1 3/8-1 5/8". The 1 1/4" is a roughed out measurement, and I can easily increase it.
I make my drawings in either Qcad or TurboCAD. I am always happy to help someone out if I can.
Thanks,
Marc
