I have been a fan of Maglula for many years. Hands and fingers are achy, so a loader is a must for me.

 

The Maglula UpLULA pistol magazine loader for 9mm on up works fine for the Security-380 magazines.

 

When I purchased my first Sig p-365...I went crazy trying to deal with loading those super tight mags.
Looked online and everyone said get a maglula...........I did and WOW! what a difference. It stays in my range bag and I don't leave home without it.

They are about $28 at Gun/mag warehouse.....you may can find it cheaper?? Most gun stores will be higher.
