How are you "letting the slide go forward?" Reach over the slide, thumb to the rear, and aggressively cycle the slide. The old "Flying Ashtrays" may not cycle but I think those were 200g.

Ammo issue???
So I was loading my USP .45 today with a full mag of Speer Gold Dot 230gr and as i let the slide go forward JAM. Thats the first time that has EVER happened
Tried it a few more times. Hand cycling the slide and trying my best to let the slide go forward untouched as to not slow it down but out of maybe 60-70 more times cycling by hand it jammed probably another 6-8 times.
I have 750 rounds through this USP. Its my baby and it's never failed. But those 750 rounds were FMJ.
Anyone else have trouble with hollow-points or this brand specifically? Is it just cause I'm cycling it by hand which slows down the normal operation?
Just a somewhat troubling thought and I needed to ask

I recently picked up my 1st HK pistol, a used 45 USP. I shot it with PMC ball ammo & it was perfect. For home use I loaded in some "Flying Ashtrays" and dropped the slide forward. The gun fed fine. These were the older 230 grain rounds with the bigger opening than what is available today. GARY N4KVE
Have you ever shot this ammo through your pistol? I would becareful letting the slide cycle and feed these bullets over and over again-the risk being bullet setback on an already hot round. The best way to function test your defensive rounds is to shoot it, not hand cycle!
Have shot a great deal of Speer 230 grain Gold Dot through my USP 45 with never a problem.
When you hand cycle pull the slide all the way back and let go all in one motion. That slide should have plenty of force and should never have a problem chambering a JHP.
EDIT: Also make sure your rounds are seated all the way to the rear of the magazine..

I had a box corner crushed on a box of +9+ and did have some that were set-back. 9mm is a high pressure rd so i decided to get rid of that box. Thank's to someone who mentioned crushed boxes on this Great Forum.
The above advice is as usual spot on....
2 Corinthians 12:9
King James Version (KJV)
9And he said unto me, My grace is sufficient for thee: for my strength is made perfect in weakness. Most gladly therefore will I rather glory in my infirmities, that the power of Christ may rest upon me.
Make sure your pistol is clear and unloaded. Then field-strip and remove the barrel from the pistol. Take a few of the Speer rounds that you have NOT TRIED IN THE GUN YET, and place them into the chamber one by one, and check to see if they stick out past the barrel hood. If they do, they are TOO LONG and SHOULD NOT BE USED IN THAT PISTOL. The bases of the cartirdges should be just slightly less than flush with the end of the barrel hood. 230 grain Hornady TAP 45 acp cartridges are known to be too long in that weapon, so this is not unheard of.
The cartridges you have already tried are not a reliable guage because they may have already been "set back" (made shorter from pushing the projectile deeper into the case) by your attempts to chamber them.
HK is the way!
