Oh I don't know. Detroit Police issued them to my grandfather in the 20s, 30s, 40s, according to him they worked pretty well. Granted we have better choices.
Not this again........
Well my grandad was a cop in Milwaukee during the same time and gave them back the 38 and carried a 45 Colt.
The 38 LRN is and always was a dismal round for self defense. Just because cops use something does not make it effective-think politics.
