interesting day at the range

[fernpatch]

Went to my favorite shooting spot today with a buddy and had a blast. I introduced a new commer to the joy of 10mm and he loved it. The only dark spot is my witness had its first malfunction today. I had 4 out of 14 fail to feed in my first mag shooting underwood 180 Gold Dots. I switched to my cheap blasting ammo (180gr lax fmj) and had no further problems. Tomorrow I intend to break my witness down to see if  I can figure out why it suddenly decided to choke on the Underwood ammo.

What model? It could be the spring, magazine or shooter technique.

New shooters always have ftf's with my witness with full power ammo.  I never do.  Stronger springs seem to make this worse.

Thanks for the replies gentleman.

A little more information for you:

the witness i have is a full size steel. I am using the henning cone fit guide rod and either a 20 or 22 pound wolff recoil spring. For what it is worth I also installed a houge wrap around grip.

I was the one that had the malfunctions. I was burning the ammo that was in my carry mag as is my SOP for range time. I am hoping that problem was just me and not the gun. Thankfully it was running fine when I switched to the lower power ammo and when I let my friend run a couple mags in it it performed flawlessly for him.

I don't think I was limp wristing the gun but I did injure my elbow a while back and my dominant arm still has not fully recovered.

all of the jams that happened were exactly the same. The corner of the bullet itself was caught on the corner of the barrel hood.

Sitting here and thinking through the sequence of events leads me to hope that I am the problem and not the gun because all of the jams happened when I was focusing on trigger squeeze trying to shoot a nice tight group. when I shifted my focus to making sure I had a extremely solid grip and and picked up the rate of fire the problems went away.

I guess the fact that I normally only care about "combat" accuracy caused me to have a hiccup when I suddenly was focused on trying to wring out the smallest possible group I could.

On a side note. I have noticed that ever since I changed the grips out I cannot seat a full 14 round mag on a closed slide. I never remember having that problem with the stock grips. could the rubber grips be causing some drag or pressure some how on the mag body?

Regarding the magazine seating issue.

Could be.  Easy to test by removing the grips and trying to seat a magazine.

If that works then it is your grip.  Next question is if it interference in squeeze or height.  I had interference issues using some mags with Elite.  Same mags worked fine in my full size.  Turns out the Elite frame is just about 1/16" longer.  Some sandpaper on the top of the mag bases fixed the issue.

Here is a magazine in the Elite, fully seated:



Here is the same magazine in the full size:



The gap shows the difference between the mag release and the bottom of the frame.

Here are the base pads of three magazines.  The middle one is the factory mag for the Elite, the other two came with the full size.  This picture is after I sanded the tops.  That is why they are "hazy" looking.

thanks for the feed back. I will take a closer look tonight when get home. looking forward to some tinkering time

Finally had a chance to get my witness back on the firing line. I ran a box of target load through it with no issues and and even better was a couple of mags of underwood without fail. I attribute my issues last time to me and not the gun.

The best part was a gentleman about 6 lanes over who narrowly missed getting tagged by flying brass was wondering what the hell I was shooting that was so loud and throwing brass so far. I showed him my witness and he just about started drooling on it. I let him run a mag through it and he started grumbling about how I just cost him a bunch of money because he needs one now. I smiled and recommended he check this forum out.

The range is so fun. Thanks for sharing. Love moments like that.
