The feed ramp on a stock G40 10mm will still put a smile on your brass. More a concern for reloaders. After market barrels like the lone wolf are a little more snug and will only take certain grains/pressure configs or will stovepipe/ftf - require polishing of feed ramp and extensive testing to get a reliable feed in order to keep your brass.
