I took my new GrandPower to the range today, and I had so much fun shooting it I forgot to shoot some decent groups and test for accuracy.

The gun felt great, but it stovepiped/failed to feed a number of rounds.

I was shooting light 117grain regular round nose Remington 9mm, and then 124 grain as well. I noticed that it appeared to jam a bit more with the lighter rounds.

I don't think I was 'limp wristing' as I have been shooting a .40 the past few weeks.

Anyone else have any feed problems with their K100? Maybe it just needs to be broken in...
 
My girlfriend bought one,she has never had an issue with it feeding 124gr or 147 gr,or for that matter a single stoppage yet in 2 yrs. maybe you were just limp wristing it,then again there are a dozen things that could be wrong.
 
Is it used/old? I bought one a couple years ago used and it acted a little like what you describe. I upgraded the extractor (the newer style is on all the recent ones) and now it's 100%.

The old extractor was a piece of sheet metal that looked like a hairpin shape.

The new style (again, "new" is a relative term) is a beefy piece that is spring loaded and looks nothing at all like sheet metal or a hairpin.
 
its a brand new K100 Patrol, D series serial number

I hope that this was just first day jitters. The gun seemed to fire better when I shot it single handed. It could be my grip technique, but I had stovepipes AND fail to feed. I will provide a full range report on a warmer day.
 
I've had two stove pipes in about 600 rounds fired. I was using light 115g winchester. I've bought heavier grain for the next shoot to see if it fixes the problem. It wasn't a limp wrist problem. I tried to get it to jam that way, and only managed to jam it when I held it sideways and limp wristed. I hope it's just a 'need to break it in' problem. Good luck.
 
My K100 is also D series serial number, Mk. 6 model. The first day out I have quite a few stovepipes, and failiures to feed. Went home, took it apart, cleaned it up again, and lubed it up more than I thought was necessary, and the next day went shooting again. It shot very well. Shot it a few more times since then, working fine. Try lubing it up more than you think is necessary, lol, might do the trick.
 
I have a 2006 built K100 as well and have had no stoppages to date {700 assorted rounds} but I've noticed that it seems to like to run wetter and is more lube thirsty than any other pistol I've known.

Don't really see the point in your post.

I have been on the wall about getting a K100. It is always noice to get feed back and reviews from owners.
 
Dear friends,
the problems you are describing is caused because we tried to produce pistols with manufacturing tolerance and accuracy of PETERS STAHL guns which are priced from 2500 EUR and more,at prices who are suitable for all.
The gun with minimum tolerance of the slide it is necessary to count with better cleaning servise which should be more frequent.
When we produced pistols with tolerance common for services guns,it was no problem-have a look
here :http://www.grandpower.eu/_EN_Gallery_K100_112470.htm
this gun fired 112 000 rounds,it was not cleaned at all,after each 400-500 shots was sprayed with the bit of gun oil.During those 112 000 shots had some 48 stovepipis/ftf and that was because of using the ammo which was not a good quality.
it had a larger production tolerance and it "rattled"Some peolpe /they were Czech who still look at us from above/on the exhibition in year 2005 told me that our pistols rattle.So to show what we can do I thourugly check the production parametres and people are delighted that they can afford such accurate gun for so little money,but if they do not look after it they are dissapointed.
So we will make pistols with bigger tolerance for basic used and the pistols with minimum tolerance will be delivered as model "K100 ULTRA" for more money on special request.
Regards,
Jaroslav
 
I own an HK USP, which are known for their relaibilty and accuracy, and I was getting stovepipes occasionally during the first 1000 rounds. My dad got a CZ SP-01 and the same thing happened to him. I've heard of the same thing happening to SiG owners. It's a new gun, stiff spring, give it a little time and it will eat anything.

Keep in mind 9mm pistols were DESIGNED to shoot 115 grain bullets.
