Hey all,

I met up with BrentSc at Sharon today, and torture tested his K100 with about 400 rounds of various types of 9mm ammo (115gr, 124gr, 147gr, FMJ, TMC, Remington factory, Winchester, Winchester WinClean, Wolf, etc).

I can consistently make it fail to feed the last round in the mag, during rapid fire. This seemed to be happening mostly to FMJ bullets, but it was not limited to any bullet weight or manufacturer.

I'm not saying there is anything wrong with the gun, it looks and feels great, but FOR ME it would require tinkering to try and make it work consistently. I'm sure it's just a function of how I hold it, or whatever, but as much as I liked shooting it, I'll stick to the NP22, since that works 100% of the time...

Haha, I thought that my NP had a short trigger reset. After shooting 300 rounds from the K100, I picked up the NP for few mags, and I was shocked to see how much longer its reset is from the K100!!! Haha, the K100's trigger spoiled me, totally!

How can you say that there is nothing wrong with the gun if it consistently fails to feed the last round? :? I don't think a quality gun should be that sensitive to grip (or to limp wristing). Doesn't marstar have an iron clad guarantee or something along those lines? Can't you send it back and request a replacement?
 
First, let me thank Omen for his hospitality at having me out to Sharon. I had a great time trying all his different 9mm's (sig, glock, cz, various norinco's, 9mm AR, etc.). I also was able to take advantage and sight in my hunting rig. Thanks again.. He is a fine gentlemen and great Gunnut.

All the testing was done with the original 2 mags. Before the testing, I took both of them apart to make sure the spring was seated properly (as Yaro recommended)... There was nothing out of place internally on them.

I can most definately say Omen does not limp wrist the gun. He is a fine shooter with an amazing speed and cadence to rapid firing...He can go through a 10 rd mag extremely quickly with all shots in the A zone. I am sure some other members can comment on his shooting stlye and competence... but bottom line, I highly doubt this last round failure to feed is due to him.

I am happy with the gun, and it shoots great for me. I am a casual shooter and do not (and cannot :oops: ) shoot as fast as Omen. If I was a serious IPSC shooter like Omen, yes, it would be a concern.

Am I going to call Marstar to send it (gun and or mags) back? No, not unless they want it back due to the various info posted. I like it... it has a great feel and ergonomics to me.

Regards, Brent

Haven't had any last round problems with my k100

can you post some pics of the magazines?


what colour is the follower? mine are orange.

does the mag have a small piece of metal welded inside to limit the capacity? or does it have indentations to prevent the follower from moving down too far
I have both types

what type of finish is used on the magazines? mine are blued, highly polished

does the last round hold open work?

what is happening on the rounds that fail to feed?

stove-pipe (sideways)
fail to strip from mag?
nose dive and lock the slide back?
get hung up entering chamber?

does the last round fail to feed for everyone? or just Omen?

I seem to be the only one for whom this happens, that's why I tend to think it's a problem with the K100+ME combination, rather than any problem with the gun. For example, I had feeding issues while shooting my CZ-85C which were not encountered by anyone else shooting identical guns, so, I donno...

Re what was happening, the last round was going in at a wrong angle, too steep, and what happened was that it would go in about 89% of the way in, but not all the way. THe slide would be ALMOST closed, but not quite - there was a little bit (maybe 5mm?) of the round still visible in the not-closer chamber...

The followers were black, and the mag had a dimple on the back, which I'm guessing is the 10-round limitation - I never saw the insides of the mags. It was happening across two factory mags, during rapid fire, when I was just trying to empty the gun as far as I could...

Just Omen, my gun does not like him... :D

I could not get it to jam, but the reality is I cannot shoot the same quick interval that Omen does, unless I want to put a round in the roof... :shock: :oops: .

They are the blued high gloss, black follower, dimpled 10 rd limit mags.

side note, was kind of funny to see ppl stick their head in the range door wondering what all the noise was...when Omen lets go with 10rds and the short trigger reset of the K100, sounds like a machine gun.. :D ..AND that is with all the rnds in A zone.

haha :lol: That's too kind! Nice gun makes that easy!
 
hey friends,

I would like to say something concerning the feeding problem of the K100,
The firts series of our gun have come to Canada with 15 rds magazines because we didn´t know about limitations in Canada. So that is possible you have got an not very well converted magazine from those of CZ, but to be sure I would like to have an picture of that. please make and send me the front view of the mag with the mag catch hole clearly visible as well as the pic of the pistol frame with the mag inserted in. these pics should help us to identify the problem...

Yaro, as requested.. PM me if you want me to email you the high-res pics, or more as needed.

Brent,
I sent you a PM,

I think that it is a problem with the magazine follower interfering with the slide stop for some reason. We did have a few sent to us that were out of 'spec'. I thought we had caught them all but maybe we missed yours.

Again - check your PM's and we'll get a good one sent out - hopefully that cures your trouble - or rather Omens :)

Hi, got your PM, Thanks for the offer. :D .. I will let Omen beat up on the new mag to his satisfaction... There is a tiny voice inside him wanting to buy two K100's for his IPSC needs... :twisted:

Ohhh, God, all the troubles I'm causing... :oops:

Haha, let me know when you want to take another trip up to re-sight in your deer rifle while I try to break the K100 again ;-)

Thanks, all!
 
Hi. Sorry , but I think problem is no the mags. problem i see at steel insert, strictly speaking at leading manger. this one homing cartridge into barrel.
top end of this are ending by sharp angle. ( its at steel inserts from begining of our production now we made it with radius R3) this sharp angle, with combination anything situation (speed fire, braked spring, mud in mag) sometime caused this "F2F". Solution : take you hardening (diamant)smooth cut file, and making donw this sharp angle. or you may use the grinding machine.
Please accept my deep apologize for this. with standart 17 ronds mags it was caused only when springs in mags was very weaking, or when mags was internal dirty(with combination of sharp angle of end of leading manger).probably this 10rounds blocking overpress caused braking of mag spring and with combination this sharp angle end caused problem.
Thans for yours uderstanding.
and sorry for my terrible english
Yours
Yaro
 
Yaro,

You, and your excellent responses to your product, have definately sold me on the K100. As soon as I have the funds I will be picking one up. Top notch customer service!

Cheers to Yaro! :mrgreen:
