Cz 75bd Break In?

[rjk2475]

could'nt pass up a great deal on a new cz. my only issue is the very heavy DA pull. will dry firing/shooting lighten it up?thank you

Put about 5000 trigger pulls (rounds down range and dry fire) and that trigger will sweaten up very nicely. I have a 75B that is smooth as silk in DA. If you have the $$, invest in a Kadet Kit. You won't regret it.

The easiest way to make the trigger pull better is to switch out the 16 lb hammer (main) spring with a 15 or a 13 lb main spring.

You can also send the gun to Mike Mink (czshooters.com) or Angus (czcustom.com) and they can do a trigger job that will include replacing the main spring and polishing the various fire control components. Also often they will replace the hammer with the competition hammer.

As Calhoun said, dry fire it and work the decocker while you are watching TV or something and the trigger and decocker will smooth out nicely. Also, be sure to use snap caps when dry firing. A-Zooms are nice. Just be sure to always load a chamber by inserting a magazine and cycle the action.

NEVER lock open the action with no magazine, manually insert a round into the chamber, and release the slide so that it slams down on the cartridge to chamber a round. This will likely break an extractor.

A bit of polish on the sear and hammer with a corning stone and cutting back the hammer over cam cant hurt too.

Something of note about the decocker models is that the hammer starts from about a "one-third-cock" position, shortening the trigger stroke (i.e., length of stroke or pull) by that amount. I find the trigger action on my 75D Compact PCR to have a short and smooth - but not light - DA stroke, while the SA pull is still a little rough and scratchy. But there has been considerable improvement after some 700 rounds fired.

My P-01 smoothed up nicely after shooting some rounds and dryfiring.

I'll second the lighter hammer spring. I have 15lb. hammer springs in my czs and they work fine and lighten the pull. I wouldn't go as light as 13lb. because you might start getting light hammer strikes. Mark

just took my new BD to a really good 'smith for an action tune(reduce creep, lighten DA). anxious to shoot it.

At one time, CZ would have their 75's in a machine that dry fired them while being bathed in an oil bath. I think they got cycled at least 1K times. At least that's what I read years ago.

Anything except Federal Primers will have a 1-2% failure rate with the 13lb main spring. But Federal primers are fairly rare out side of ammo made by companies owned by Federal. Winchester primers seem much more common.
