Breaking In A New Mark III

[0x80884]

I just purchased a Mark III and it's out of jail this Tuesday. I've heard mixed posts all over the internet about break-in time, types of rounds, etc.

This is a first handgun for me, so I'd like to do it right. I've got bulk federal hp, cci mini-mag hp, remington gold bullet, and some cci stingers.

What should I be shooting for the break-in period? I'm picking it up Tuesday and hitting the range this weekend due to work. It'll be disassembled per the manual, cleaned up right, and properly reassembled. Then what do I grab to go with me to the range?

After taking it home, are there any little known spots to triple-check during cleaning, or little known facts I should be aware of?

Thanks Calguns!

i might have made a mistake in so doing but i just took my new mark iii to the range and fired 50 rounds of winchester something and 50 of federal game-shok and it went well. no jams and when i came home to clean it it was effortless.

It should shoot any .22LR ammo with no problem.Neither my MKII or MKIII required any sort of break in.Now that my MKIII has had a couple thousand rounds thru it,I've ordered a MKII hammer bushing to eliminate the magazine disconnect and an LCI filler plate to eliminate the LCI.This should improve the trigger and enhance reliability.Have had zero problems so far.

With any new firearm, you should clean and lubricate it before starting to shoot. The manufacturers usually put rust preventatives and grease for long term storage that should be removed. Some heavier than others.

Yes, and yes. I cleaned mine before I took it out but today, after 500+ rounds I took it completely apart except for the one spring that goes down by the mag release. I found that nasty, sticky brown grease in everything including inside the mags. I noticed one of the mags springs was rough and when I took them apart it was in there too.

I ended up cleaning the stripped frame with dish soap and water, then blow out with air. Perfectly cleaned and oiled now.

As far as break in, just shoot it.

If it were myself I'd just take along any type of "high velocity" ammo. I usually prefer CCI "blazer".

Breaking in one of these (as with any pistol IMO) is just take it to the range and shoot it 500 times. Enjoy your purchase, you made a nice choice!
