Well, 158 +P "treasurey loads" are far more proven than mak ammo. With only 95 grains, I'll worry a little about adequate penetration. I KNOW the .38 will work. It did end the Miami shoot out, after all.
I do agree, don't sell the east German mak, just buy the Taurus. You trade that gun away, especially if it's a good shooter as most maks are, you'll kick yourself some day. When you get that Taurus, you will likely find yourself carrying it a lot more than the mak, but hey, they're not in short supply. Just save, as mentioned, and get it.
I'd like to get a mak, actually, been thinkin' about it. I kinda would like an LCP first, though. Then there's this desire for a PT145. Too many guns, not enough money. I could have gotten a comercial mak in .380 acp for 260 not long ago, thought about it, but I think I want it in 9x18 even though I do have dies, a bulllet mold, and loads for .380 already. 9x18, at least before the election, was pretty cheap off the shelf. Not even sure it's worth handloading for, though I have dies for everything I own that goes bang.
