Again, note that these are strictly for full wadcutters and not for standard .38 Special ammunition. The full wadcutter is seated flush with the case mouth, so the maximum length, even with a small rounded tip sticking out is under 1.15" long. That is within the 1.275" maximum of .45 ACP hardball, so it can fit in a magazine that fits in the magazine well of a 1911 frame. A round nose .38 Special at 1.55" would not.

The old Colt National Match pistols preceded the series 70 and had more hand work in them. Many are well fit guns.
