Shot Out?
Maks have crome lined barrels,.....I doubt it would be possible to shoot one out.
.22>.45 I would just go practice some more.
Maks are not going to print dime sized groups but they will keep everything in the "coke bottle" on a siluette at 25 feet which is Waaaayyy acceptable combat accuracy.
I can keep a group in side a 8 inch circle if I am trying hard.
I would go get about 300 rounds (six boxes) and go fire them up.
wait a coupla weeks and do that again.
your proficiency and familuarization with your pistol will improve dramatically.
Your makerov Pistol is only half of the weapon system
You are the other half.
with Practice I know you will suprise your self.
Try this excercise.
Go and get a 2 standard bullseye targets
fire 8 rounds in to the first one.
stop, score it date it and put it away.
shoot up the rest of the 300 rounds.
Go home and Clean the !!!! out of your pistola.
next month with another 300 rounds on hand.
Go again, take the second target fire 8 rounds again at the same range
score again date again, put it away and fire up the rest of the 300 rounds again.
by the third or fourth time you do this your scores will get better.
see the true test of how good you are is those first shots when you are cold with no practice
that skill is called "muscle memory"
after so many years I Still need to practice because accurately shooting a firearm is a perishable skill. It is NOT like rideing a bike
in order for me to be able to KNOW I can hit my target under stress at a moments notice I have to practice.
once a month is ok but the more the better.
getting good with your makerov is easy and a good confidence builder.
you have the tool now you need to get good at useing it.

Good Luck
