Msg73: I'm still considering frame or slide mount. I want to find someone with a slide mount of some type to see how it shoot because obviously it is a cheaper approach. I have the esp magwell but still haven't ordered the tf baseplates. I've looked at the slc products and they look promising. You also bring up a valid question, how big of a difference will the average shooter see between the different platforms.
Joe4D: I have a feeling that this project may end the same. However, I enjoy this type of project and worst case I end up with a giggle worthy m&p open gun and a 2011 down the road. But who knows, maybe I'll be perfectly happy toying around with the m&p.
Kneelingatlas: I know exactly what you mean, I sometimes wounder if I prefer working on the guns or shooting them more. Why not enjoy the challenge of the build and just shoot for fun. Even if you finish last every match I doubt anyone would complain about spending the day st the range.
Wes77: I have definitely thought about just running minor in open. My current thought is to initially build for major and worst case have minor as a fall back. Luckily I enjoy playing with loads so even playing around with trial major loads will be enjoyable. Even if this project waste 5 years, I can still switch to a 2011 before I'm 30 and have plenty of years of fun shooting ahead if me.
Again, thanks everyone.
