The 158 gr. advantage
More likely a comparison is the .380 autos to the M36, than a small 40. The 40 round outclasses the smaller rounds, but I would see how it handles in a mini gun before buying! The 38 has a wider range of bullet options than the .380. And I don't think I ever have to worry about my 60 or 640 going bang or jamming. Probably don't have to prove each load with a boxful to be confident of how it shoots. THey recommend a large testfire expenditure of a chosen load with the autos, for self defense reliability. With the rev., if one cylinder full plays OK, I figure any more rounds fired are just for checking groups, not worrying about future malfunctions! These small guns work great with Uncle Mikes boot grips or some other rubber grips, and the 158gr. hollowpoint. I don't know about the Winchester load that the other post said was hard to find, but any gunshow sells the Win. X38SPD plus P LHP which may be the current version of what he mentions. And it groups right on top of the front sights at 15 yds. with my guns. Well centered, if not a tight target wadcutter group!
