To be honest I’m mostly familar with Makarov and TT. I also used Stechkin, PB and MP-443 but I like TT best though.
Was the Makarov standard issue in your unit?
I've owned a couple of East German Makarovs, which use 9x18mm "Kurz" ammunition. They carry a good bit more "pop" than a .380, and I've found them to be very reliable with respect feeding a wide range of 9x18mm ammunition variants.
As a backup weapon, I highly recommend the Makarov, especially when manufacture in the "right" countries.
Obviously not as much stopping power as a 9mm para., but these standard blowback pistols strike an excellent balance between stopping power, reliability, concealability and size/weight. It's been a while, but last I checked, very nice specimens could be had for $250-$350 or so.
