Cleaning P-01

[MMH]

I put 300 to 400 rounds through my P-01 since it's las cleaning and at the last shooting session the slide would not lock back reliably on the last shot so I figured that it was time to clean again.  Otherwise function was 100%.  I was shooting fairly low power ammo and figure this was a fairly benign failure.  This is my primary carry gun.  I'll start cleaning it after 200 to 300 rounds from now on.  Does this seem about right for a carry gun?  Do any of you guys clean after each firing session?

Also, I generally oil every thing and then grease sliding contacts.  This 'waters' down the grease (I use TW25) a little.  Should I keep the oil off of the parts that are greased?

I clean anything I shoot after each range session no matter how many rounds I fire. I oil anything that moves and I don't use grease ever. Others may do as they wish and will but this is my routine. Guns I carry get shot regularly and cleaned regularly. Even if I don't fire my primary defensive pistol for a few weeks it still gets a weekly wipe down and a patch run down the bore to remove any accumulated dust/dirt.

i also clean after every shooting session regardless of round count. your issue could be the magazine followers/springs getting dirty and not engaging the slide catch when empty.

• P01's are considered a self defense weapon and as such they expect you to be firing fairly potent SD ammo.

• It's the ammunition that creates the energy, which ends up moving the slide to the "lock back" position.

• The slide's return spring and gun's hammer spring are what resist the rearward movement of the slide, ultimately slowing the slide before it arrives at the "lock back" position.

• From what you have posted, it seems you have 2 co-existing issues going on here...
1) IMHO you have created some of the issue yourself by using low-power ammunition in a gun that is sprung with high-force springs. If that's the way you prefer to practice, then order something like a 14# slide return spring from Wolff Gun Springs and slip that in at practice time. Click Here.Fitting of a full-time reduced weight hammer spring might also be considered.

2) As noted in the FAQ section, new CZ pistols can require a break-in period which is generally considered to be 500 rounds minimum. Click Here. Additionally, I recommend 1 drop of clean, light-weight, synthetic motor oil on each of the slide rails for metal handguns.

Hope this helps.

If I shoot it, I clean it.  There are days (frustrating days) at the range where I'm trying to get a different brand of pistol or ammo to shoot good groups and need to know if it's me or the new gun/ammo.  I pull my concealed carry P07 .40 out of the IWB holster and shoot 5 shots and I know if it's me or the new gun/ammo.  When I go home the P07 gets unloaded, field stripped and cleaned/lubed before being reloaded to make it ready for the next trip out of the house.  And yes, I pull a spare mag out of the mag. pouch and insert it into the P07 before getting in the car to go home.

As for oil/grease, I don't use grease on a handgun.  Just on the M1 Garand, M1A and the SIG 556R.  Not telling you to stop greasing, just saying I don't.

As for not locking back after that last round I wouldn't think 4 or 5 hundred rounds would cause that problem.  Have you cleaned the magazines?  I start of wiping the outsides of the mags. down with the same oily rag I use on the gun but eventually will disassemble the mags, degrease/clean them inside and out and then use some car wax (like Nufinish) on the inside and outside to protect the metal from corrosion, make them work slicker (you can feel the difference when loading rounds in the mag.) and help them repel some of the dirt/dust they pick up being carried around all the time.

What about new/stronger springs for the mags?  I've replaced springs in some S&W mags. that wouldn't lock the slide back.  Bought stronger springs (+10% strength) from Wolff Springs.  Zero issues since.

I quit using grease on pistols.  I use Wilson Lube II in real hot weather and the rest of the time use Mobil 1.  I have a P01 omega.  It quickly became my main range gun.  The other day when I was cleaning it was really nasty inside and the trigger a little gritty feeling.  I flushed it with gun scrubber.  Then cleaned it with a toothbrush.  And then another shot of gun scrubber and blow out with air hose.  Then a few drops of oil in the hammer area and a drop on the trigger spring and mag release.  A few drops on the slide rail.  I don't think it's ever been that smooth before.  I probably have 2500 through it and using the 13# spring.  Double action is 8# and single is 3.5#.
