As someone else mentioned, hopefully this problem will disappear as the mag spring loosens over time.īut my main concern is still the chewing up of the recoil spring assembly base. But I guess that’s better than 7+1 round stuck on. If carried this way the capacity is reduced to 6+1. Of course this isn’t good as the pistol only holds 7+1 to begin with. It just seems to happen when the mag is full. round from the magazine none of the rounds catch on the feeding ramp. As someone else mentioned, If I remove the 7th. All the rounds I mentioned earlier (Gold Dot and CorBon) cycle fine most of the time if I rack the slide very hard as it would probably act when firing. I’ve noticed something since my last post. I suspect that the 135gr Hornady Critical Defense cartridge should be a little longer, and it may mitigate the issue completely. If you are having this issue, I’d recommend trying a cartridge with a little longer overall length. I’m also going to attempt to rule out the bullet profile, as I really like how the Hornady projectile performs. I think Springfield Armory tried to mitigate this issue by relieving a small portion of the locking block under the feed ramp, but when you add the short cartridge to this small pistol it becomes a perfect storm, and things don’t work quite as nicely as we would like them to. Here’s where this all gets even more interesting: I’ve fired exactly 50 rounds of the Hornady TAP FTP through this pistol, and all of them have fed, and fired just fine while on the range, the feeding issue only occurred when loading the pistol at home. The more rounded shape of the HST closely mimics the shape of ball ammo which has been 100% in this pistol. I also suspect that bullet profile may be playing into this a little bit. I turned my garage upside down looking for my calipers so I could give you an exact OAL for each of these rounds, but they are still missing…īeing that the HST’s are longer, this allows the bullet to contact the feed ramp and start traveling up toward the chamber before the case rim passes the bottom of the feed ramp/locking block. The Federal HST rounds (left) are a good bit longer than the Hornady TAP FTP rounds (right). To confirm, I scrounged up 7 rounds of Federal HST 124gr +p, loaded them into the magazine, and chambered and unchambered them over 100 times. I noticed that the Hornady rounds were quite a bit shorter than the snap caps were, and I think this is actually the issue. I even tried applying pressure on the top round (with a small piece of wood so I didn’t smash my finger…), pushing it toward the bottom of the feed ramp, and I still couldn’t make it jam. I proceeded to rack the slide, chambering and unchambering the snap-caps a whole bunch of times, and not once did the pistol jam. I shucked the 7 rounds of Hornady TAP FTP out of the magazine and loaded it with 5 A-Zoom snap caps. You can see how far the round traveled forward before it jammed the slide open. In the next picture below, I’ve pulled the slide rear and locked it. When I looked in the breech, I could see that the round was caught up either on the bottom of the feed ramp, or on the ramped part of the locking block below the feed ramp. I tried giving it a tap on the rear with my palm, and it would not go into battery. You can see in the below picture that the slide is not locked to the rear, but it has slid forward, and is being held open by the round that is jammed inside. The slide traveled forward about 3/8″ then stopped. I’m pretty good about not riding the slide forward, or short stroking it, and I let it go. Here’s what happened: when loading the pistol, I inserted the magazine and pulled the slide rear. Last week Brandon over at Monderno mentioned that Rob Pincus was having some failure to feed issues with his XDs 9mm, and I came out and said that mine had did it once, but after I ran a few rounds through the pistol, it never did it again.
