He mistakenly purchased .380 cartridges for it.
He later sold it to me, along with the cartridges he had for it, which is how I discovered his error.
He said it was reliable. I often wondered what sort of accuracy he achieved with the mismatch.
The Makarov pistols have a reputation for reliability and accuracy.
I haven’t played with my pistols for a long, long time. So, the details are getting vague as to which 9mm ammo doesn’t work in which pistol. I have purchased from lots of manufacturers and some of the ammo is fractionally longer than the ammo from the other manufacturers. A few of my (cheaper) guns fire both lengths with ease. But I have one pistol which I finally stopped carrying because I kept hitting the magazine release by accident. But that gun would only chamber and fire the slightly shorter 9mm rounds. Have you ever come across this issue? If so, how do I avoid buying the wrong ammo?
