On Tuesday I was at the range trying to use Federal American Eagle 230gr .45GAP FMJ in my G39; however, I was getting so many failures to return to battery, that I gave up and switched to my G26 that fires everything I've ever fed it. Just eyeballing the rtb failures, I'd say the slide was about 3/8" short.

I had no problems with Double Tap 185gr or 230gr .45 GAP HP's.

Has anyone had similar experiences? If so, what was the solution?

Thanks!

ps I did a search with the terms "Federal Eagle G39" but found nothing.

You could have a box of out-of-spec ammo. It happens. Take the barrel out of your G39 and drop every round into it. They should drop in freely, all the way, and drop back out freely.

Danny,

I did as you suggested and discovered the Federal rounds dropped in and out freely, but protruded about the width of the rim above the ramp. The DT rounds, however, fit flush. Could that tiny difference be the problem, or do I need to look to some other cause? The reason I ask is because the rtb failures left the slide about 3/8" short of battery, and I can't account for the difference, but I'm not at all an expert.

Thanks for your help,

m

Sounds like you have some .45ACP packed in a .45GAP box, or the ammo is really out of spec.

Thanks again for your help, Danny. I tried the same test you recommended with another box of the Federal, and sure enough, the fit was flush just like the DT rounds.

I shoot about 10,000 rounds per year through my Glocks. Although most are my reloads, I barrel check or gauge check every reload and factory new round. It eliminates problems like the one you experienced.

I went thru a 50 rd. box of 230g. federal eagles the other day and had 1 failure to return. :whistling:

Do failures occur with the G39 often or is it just this ammo that contributes to this problem?

Could it be that it is a sub-compact that makes it more susceptible to limp writsting which can result in jamming?

The problem was ammo specific--out of spec rounds. The problem experienced with this batch of ammo would have been repeated with any pistol chambered for .45GAP. Out of spec is out of spec and is no reflection on the pistol using it. I have experienced out of spec factory new ammo in .380, 9mm, .40S&W, .45ACP and .45GAP. It happens.
