My makarov is one of my favorite guns. Extremely dependable and accurate, but its heavy and only holds 8 rounds, so not my go to gun.
I carry a keltec P11 daily. I'm not usually a big fan of the small guns but the double stack gives it a nice fat grip and it disappears iwb. But, I too had a lot of problems out of the box with it. Problems loading, cycling, and forget about using hollow points. Luckily I have a friend who's dad is a retired gunsmith. So I let him take a look before I traded it off. He said keltecs are some of the roughest machined guns he has ever seen. But after he got done smoothing everything out and going over the trigger it is a really nice piece.
