Gen 4 9mm - ammo recommendations?

    As I continue researching Gen4 Glocks for my first Glock purchase, I'm finding there are brands / types of ammo to avoid in the Gen4 9mm pistols to avoid getting hit in the face with brass, namely Federal Champion 115 gr FMJ from Walmart.

    Now I've run a thousand rounds or so of this ammo through my SIGs and have not had any problems. But I guess a Gen 4 Glock may not be on the same level of reliability/durability as a SIG? I don't know.

    Are there specific brands of practice/FMJ ammo that are generally recommended to minimize brass to the face?

    Other than the Federal Champion stuff, I've mostly shot Federal American Eagle 124 gr, Sellier & Bellot 115 gr, WWB 115 gr. I rely on Federal 124 HST or Speer 124 gr GD (both sometimes +p) for carry. Are these brands ok? What are you guys running through your Gen4s to avoid BTF issues?

    My Gen 4 G19 brass to the face problem was not ammo related. After trying a few different things, I finally resolved the problem by replacing the stock extractor with an old style 9mm extractor from Lone Wolf. I've run 500-600 rounds of different grains and quality since then with no problems. Hope this helped.:wavey:

    I have shot walmart ammo through my gen4 17 and had no problems, the first 400 rounds I put through it when I bought it were from walmart, just because I was in a hurry, and walmart was close. Had zero issues with brass to the face.

    Was this the extractor that you bought?

    Some here who know far more about Glocks than do I seem to suggest that the first couple hundred rounds be Lawman 124 grain. I am going to go way out on a limb here and guess that some of the 124 grain NATO ammunition might be a marginal substitute if the Lawman were not available.

    For practice ammo---Silver Bear and Brown Bear. All my 9mm Glocks eat them up no problem.

    For HD--I generally stick with GDs and HSTs; never had a problem.

    The 124 NATO ammunition is slightly hotter than the 124 Lawman or 124 American Eagle and they all work very well.

    With regard to the brass to the face, it seems that some of the Gen 4s have the problem and some don't. Rather than attempt to correct the issue via ammunition, you may find it easier to simply replace the extractor. It's warrenty work and won't cost you anything. With regard to the ammo, 124gr seems to be the middle of the road choice. Following suggestions from knowledgeable folks here, I've tried 115, 124 and 147gr. I really like the heavier ammo but until and unless I start reloading, I won't use it much at nearly $5 more per box of 50. The 115gr is the hottest of the bunch leaving the 124 as the most managable and cost effective. Best of luck. :fishing:

    The Federal AE and S&B ammo seems to be pretty consistent (almost boring) stuff regardless of the gun I put it through.

    There is no practice ammo to avoid other than AMERC cartridges. The rest will be practice or carry ammo.

    All the lower pressure/price point ammo is not ejecting strongly out of new oversprung glocks.

    The real carry ammo is shooting good.

    We have a mix of Gen3 and 4 running now.I see them on the line a bit.

    If you want to fire lower power ammo a change of recoil spring is a good idea. Use the stock one for self defense loads. But only if it doesnt work with the low power stuff.

    Fed Champion 115 gr seems to be OK. BUT, I will get an occasional 'over the head' ejection.

    Aguila 124 gr. which is a bit more stout ejects very nicely at the 4-5 o-clock position.

    Note that as in my oen posting on Gen 4s, when I eject WITHOUT a mag, the 115 gr stovepipes, and the 124 is perfect.

    Gen 4's were definitely setup for stouter ammo.
