Please be aware that you shouldn't use .380 +P ammo in a Glock 42. Why?

• Unlike many other rounds, there is no standards around .380 +p pressures and I'm not aware of any manufacturers that endorse the use of .380 +p.
• Glock does not endorse the use of .380 +p rounds. It may not cause any damage to your firearm, but it also may not work properly.

Since the .380 is considered a marginal self-defense round, there has been a long-standing debate about using FMJ (solid) vs. using HP (hollow point) bullets. Unfortunately, .380 FMJs tend to over penetrate, while most .380 HPs tend to under-penetrate. ShootingTheBull410 has done an excellent series of YouTube video's providing detailed analysis of .380 HP rounds. I understand if you aren't enough of an ammo geek to want to view all of the details, but the OP should at least view his "best of" selections.

The original .380 tests were done in 2013 with a micro pistol, but ShootingTheBull410 did an update for the G42 in 2014 that didn't change the results significantly.

Thanks for the post, very informative.

welcome to ingo. I have never heard that before and i think its a myth. i geneally shoot fmj for practice and then carry jhp that have proven to be reliable and shoot to point of aim in that particular gun. The only guns i have put a lot of hollowpoint rounds through were my .22lr pistols and rifle and it never hurt anything in thise guns. I think you were given bad info.

Welcome to INGO! While this doesn't speak directly to your question you may find it useful: Handgun Self-Defense Ammunition - Ballistic Testing Data

The tests don't cover anything but HPs but should you decide that you want to change which HP you use this would be a good place to start.

There are some +P+ Hollow points that can and will destroy some polymer guns. Possible it's what he's referring to?
