    G3 - Need to Polish Feed Ramp

    After finally digging in to my occasional FTF on a new G3, it appears that the feed ramp is rough. In fact, the very end corners of the ramp are almost sharp enough to cut skin. There was also a large amount of carbon after only 80 rounds. Blazer Brass is not typically filthy. I'm going to break out the dremel, felt cones, and some Flitz to see if I can smooth some of the sharp points. Any advice?

    I wonder if the corners of the feed ramp actually come into contact with the bullet being fed into the chamber. Was there indication of abrasion there? I usually polish feed ramps but do so sparingly as it is one of those things where too much can be as bad as too little. My Sig P320 in 45 ACP came to me as a reconditioned Red Box gun from the factory. The ramp is coated with a rough oxide type finish yet feeds ammo just fine. Owners have cautioned against polishing them as they are sent out just the way Sig likes them.

    Before you do any polishing, use a dry, Teflon type lubricant to see if the situation improves. If you must polish, use your finger, a soft cloth, and jeweler's rouge. Metal removed cannot be replaced.

    ok, now my range report.

    50 rds of 115 gr Remington range ammo, and 50 rds of Blazer 124 gr ammo. both were FMJ

    Not ONE jam, failure to fire, nor stove pipe. Not ONE failure to eject.

    i had 2 RSO's look at this G3c, as each one had experience (and ownership) of previous models. BOTH LOVE this new updated G3c. the trigger is super good, to them. the shooting is spot on.

    what we have found is that we need to get a good grip on the trigger, (cover completely with the finger) as many shots by me and the RSO's had found that, you're gonna shoot to the left.

    once a better hold/grip on the trigger? bullseye every time.

    it is a bit snappy, which is to be expected for a compact, over my collection of full sized guns.

    the feed ramp on mine, was as smooth as a baby's butt.

    when i got home, i field stripped it, the usual amount of carbon was there, and cleaned up with Hoppe's and i lubed it (as all my guns now) with Weapons Shield.

    so that's about it, i might post pics of my targets, but they are not really grouped well, so i attribute that to not gripping the trigger properly.

    funny too, as the RSO said, "each gun, we have to learn which way to grip that trigger, as each fires differently with different grips on the triggers"

    that couldn't be any more truer today.

    i like this gun, glad that for $300 (including sales tax), that i bought it.
