I have to say it's not an SP89 but I'm very impressed with the quality and functioning of my MKE pistol. I've already ran 350 rounds flawlessly without a hickup. The exterior and interior quality of mine is darn close I think to HK. The welds look nice and finish is great. I can't wait to get my stamp and throw a B&T folder and pistol grip HG on it.

I too think that MKE manufactures a great pistol.
One thing I felt a need to do was place a bevel on the bolt carrier where it contacts the hammer while cocking. The carrier was being marred from the 90 degree edge of the carrier. The bevel made a huge difference in cocking ease.
Might want to check yours.

You made me want to break mine out to take a look at the bolt carrier. Mine doesn't have a bevel on the rear edge, but it is worn slightly round from firing. I've never noticed a problem cocking the carrier back manually and everything functions as it should on range days. I wonder if maybe you had a stronger hammer spring that made the friction too much between the hammer and carrier which is what gave you so many failures?

I never had any failures.
I didn't think the marks on the hammer from the carrier were appropriate. If you look at the firing pin retaining plate on a 1911, you will see that it is rounded/beveled to ease the cocking of the hammer.
I could imagine that a squared off carrier might slow the inertia of the carrier assembly to cause FTE issues. Check out images of other bolt carriers and you will see many have a bevel.

Good grief! That makes all the sense in the world. I have a Z5-P I bought recently and while I love the gun, it is damn hard to charge. My wife can't even charge it. I just check and my bolt carrier has a 90 degree edge, looks like I need to fix that right away.

How would you recommend beveling the edge? Stones and/or fine files? Of course I would start slow and only take a little off at a time.

I did my friends with a diamond hone to break the edge and finished with buffing wheel on my bench grinder. It polished to a mirror finish and made a huge improvement.

The carrier is hard material. I used a die grinder to establish the initial profile then a honing stone to polish. I use Brownell's action lube on the carrier and hammer contact face.

Mine's tight as hell too, but it's much easier if you push while pulling the charging handle. Hopefully it will break in with use.

Please provide a pick of where you did the bevel. Curious to see it. Thanks

I use Brownell's Action lube, on carriers, slides and trigger sears. Works great and stays put.

I got my z5rs about a week ago and the overall quality is very good. I pulled it apart to clean it because they did not clean it after test firing it, I noticed the back of the carrier is very slightly rounded and there is a contact mark on the hammer but could not feel it with a fingernail- also it is easy to pull back the charging handle all seems ok.
