Hello. I am building a 9mm bull barrel w/n 1911. I have both brand barrels on hand and can't help but notice the feed ramps are very different. The Bar-Sto ramp runs half as deep and is less steep. The Schuemann ramp runs the full depth of the lug and is much more steep. The Bar-Sto seems more than deep enough and looks like it would feed more smoothly. What are your opinions on the matter? The Bar-Sto looks like a better setup to me. Any advice is appreciated. Thank you.
