I've used 3D Reloaded Ammo in two of my Sigs a P220 and a P229 .40. I shot steel plates with my P220, 100 rounds with no problems. The next week without any cleaning, I went to shoot paper and I couldn't drop the slide on a fully-loaded 7 round mag. The top round in the mag nosedived and the soft lead of the bullet hanged up on the front lip of the mag.
It worked with 6 rounds in the mag and was unbelievably inaccurate. I only had about 10 misses when I shot steel and I don't know how I managed that because this stuff would not group at all on paper. It's extremely dirty as well. I had no problems at all shooting it in my P229 but it too was very inaccurate. Both .45 and .40 I shot were underpowered and noticeably so.
I never ever had a jam in my P220 before except for a POS Promag 10 round mag. All other ammo and factory mags it is flawless. I now almost always use Blazer aluminum cased stuff as it's so much cleaner; makes cleaning easier. I'll go many many rounds without cleaning and the gun is still pretty clean and functions fine with the Blazer stuff.
If the 3D stuff is cheap enough, it can't hurt to try some. Just remember, it's dirty as hell and cleaning your gun will be a chore. Plus, it spews a lot of "smoke" that I'm sure isn't too good to breathe, especially in an indoor range.
