But carry guns arent competition guns. I have a carry gun thats flush fit and has an extended mag for capacity both from the factory by design. Magwells and basepads add bulk and increase printing. The thing about the original drill is it still applies to all pistols regardless. The new technique is faster, has merit based on the design of the gun. Its good to see the evolution in training but it may depend on the individual preference if they want to train pistol specific or in general if they own different guns that they for self defense. I think that would be an important distinction for a student to be aware of.Harder to seat a fully loaded magazine with the slide forward without a base pad...again 1911 comes to mind.
Competition drove that modification.
